Using Bioacoustic signatures for Identification & Authentication

Filed under: Computer Security,Computer Software,Emerging Tech,My Thoughts,Tech Related — Suramya @ 9:35 PM

We have all heard about Biometric scanners that identify folks using their fingerprints, or Iris scan or even the shape of their ear. Then we have lower accuracy authenticating systems like Face recognition, voice recognition etc. Individually they might not be 100% accurate but combine one or more of these and we have the ability to create systems that are harder to fool. This is not to say that these systems are fool proof because there are ways around each of the examples I mentioned above, our photos are everywhere and given a pic of high enough quality it is possible to create a replica of the face or iris or even finger prints.

Due to the above mentioned shortcomings, scientists are always on lookout for more ways to authenticate and identify people. Researchers from South Korean have found that the signature created when sound waves pass through humans are unique enough to be used to identify individuals. Their work, described in a study published on 4 October in the IEEE Transactions on Cybernetics, suggests this technique can identify a person with 97 percent accuracy.

“Modeling allowed us to infer what structures or material features of the human body actually differentiated people,” explains Joo Yong Sim, one of the ETRI researchers who conducted the study. “For example, we could see how the structure, size, and weight of the bones, as well as the stiffness of the joints, affect the bioacoustics spectrum.”

[…]

Notably, the researchers were concerned that the accuracy of this approach could diminish with time, since the human body constantly changes its cells, matrices, and fluid content. To account for this, they acquired the acoustic data of participants at three separate intervals, each 30 days apart.

“We were very surprised that people’s bioacoustics spectral pattern maintained well over time, despite the concern that the pattern would change greatly,” says Sim. “These results suggest that the bioacoustics signature reflects more anatomical features than changes in water, body temperature, or biomolecule concentration in blood that change from day to day.”

Interestingly, while the setup is not as accurate as Fingerprints or Iris scans it is still accurate enough to differentiate between two fingers of the same hand. If the waves required to generate the Bioacoustic signatures are validated to be safe for humans over long term use, then it is possible that we will soon see a broader implementation of this technology in places like airports, buses, public area’s etc to identify people automatically without having to do anything. If it can be made portable then it could be used to monitor protests, rallies, etc which would make it a privacy risk.

The problem with this tech is that it would be harder to fool without taking steps that would make you stand out like wearing a vest filled with liquid that changes your acoustic signature. Which is great when we are just talking about authentication/identification for access control but becomes a nightmare when we consider the surveillance aspect of usage.

India has the cheapest Mobile Internet in the world

Filed under: Interesting Sites,My Thoughts,Tech Related — Suramya @ 2:58 PM

Internet services were launched in India on 15th August, 1995 by Videsh Sanchar Nigam Limited and in November, 1998, the Government opened up the sector for providing Internet services by private operators. This year marks the 25th anniversary of the Internet’s launch in India and its astounding how much the landscape has changed in the past 25 years. My first net connection in 1998 was a blazing 33.3kbps dial-up connection that cost Rs 15,000 for 250 hours, this allowed you to use graphical tools to browse the internet like Netscape (which was the precursor for Firefox). For students there was a discount pricing for Rs 5,000 for 250 hours but they only got access to text/shell based browsing.

Now, 25 years later the landscape is completely different. Internet connections costs in India are the cheapest in the world as per a recent study done for The Worldwide broadband speed league by Cable.co.uk in association with M-Lab.

Five cheapest packages in the world

The five cheapest countries in terms of the average cost of 1GB of mobile data are India ($0.09), Israel ($0.11), Kyrgyzstan ($0.21), Italy ($0.43), and Ukraine ($0.46).

Conversely to the most expensive, none of these countries are islands. Further, they all either contain excellent fibre broadband infrastructure (Italy, India, Ukraine, Israel), or in the case of Kyrgyzstan rely heavily on mobile data as the primary means to keep its populace connected to the rest of the world.

This is based on sampling done in Feb 2020

Rank Name Plans measured Average price of 1GB (local currency) Currency Conversion rate (USD) (Frozen 27/04/2020) Average price of 1GB (USD) Cheapest 1GB (Local currency) Cheapest 1GB for 30 days (USD) Most expensive 1GB (Local currency) Most expensive 1GB (USD) Sample date
1 India 60 6.66 INR 0.01 0.09 1.63 0.02 209.09 $2.75 14/02/2020

If you compare the costs to prices in the US, you will notice that Internet (data) is significantly more expensive in the US as opposed to India.

Rank Name Plans measured Average price of 1GB (local currency) Currency Conversion rate (USD) (Frozen 27/04/2020) Average price of 1GB (USD) Cheapest 1GB (Local currency) Cheapest 1GB for 30 days (USD) Most expensive 1GB (Local currency) Most expensive 1GB (USD) Sample date
188 United States 29 8.00 USD 1.00 8.00 2.20 2.20 2.20 $60.00 24/02/2020

The cheap internet data connections in India is completely due to Reliance Jio. Till Jio launched their services in September 2016 the cost for 1GB of data was Rs 249 for 1GB (Airtel/Idea) & Rs. 251 for 1GB (Vodaphone). After Jio launched all other ISP’s starting loosing customers to Jio at an astronomical rate and had to cut prices in order to stay in business. Now, 4 years later we have the cheapest data in the world at ~Rs 6 per GB. 🙂 This proves that healthy competition is the best way to get good service at a competitive pricing. If there was a monopoly then they can choose the pricing as per their desire and since folks don’t have an alternate option they have to use their services.

Mozilla Thunderbird has a ‘Link Mismatch Detection’ feature to protect from Phishing & Scams

Filed under: Computer Software,Tech Related — Suramya @ 10:03 PM

Yesterday I was trying to register for a new service and as always I had to share my email address and wait for the confirmation/validation email to verify that the email address I had provided was a valid one. Once I finally got the email it had a clickable link to validate my email address that looked like the screenshot below:


Clickable link for email address validation

Since this was an email I was expecting and wanted to create an account, I clicked on the link and got a surprise. Instead of immediately taking me to the link I had clicked on Thunderbird popped up the following pop-up telling me that the link was taking me to another website than what the link text was indicating. This is new behavior that I believe was implemented in Thunderbird 68 but haven’t found the release notes confirming it. (I didn’t really spend a lot of time searching to be honest)


Link Mismatch Detected

In this case it was a benign reason because the link was taking me to a tracking site before redirecting to the email confirmation page. But the benefits are immediately obvious as this would flag the links on the phishing/scam emails that pretend to come from a bank/email provider/facebook but redirect users to a Phishing site and prompt users to verify if they are going to the correct site.

Unfortunately the fix is not perfect and needs more work as this would include all links in newsletters etc that include tracking links (which is pretty much all of them). If users constantly get the popup then there is a high probability that they will get conditioned to click on the First button to go the site the link is taking you to without reading the text fully.

Some of the users will find this to be annoying and want to disable it, so below are the steps to disable the Phishing checks in Thunderbird (not recommended). Only make this changes if you are absolutely sure of what you are doing and take full responsibility of the fact that you disabled the Phishing checks. I will not be responsible if you disable the checks and then end up with an empty bank account after having your account Phished. Also, I found the instructions on the Mozilla Forum but haven’t tried them myself so like anything else you find on the internet please validate the steps and only follow if you are sure that they are safe :).

There are four phishing preferences.

* mail.phishing.detection.enabled

i.e. Tools > Options > Security > Email Scams > Tell me if the message I’m reading is a suspected email scam

* mail.phishing.detection.ipaddresses
* mail.phishing.detection.mismatched_hosts
* mail.phishing.detection.disallow_form_actions

Try setting the mail.phishing.detection.mismatched_hosts preference to false in the about:config window, then restart and test again.

It’s great that the Thunderbird team is adding more and more features to make email safer. Looking forward to more such features in TB.

Well this is all for now. Will post more later.

Emotion detection software for Pets using AI and some thoughts around it (and AI in general)

Filed under: Computer Software,Emerging Tech,Humor,My Thoughts,Tech Related — Suramya @ 5:32 PM

Pet owners are a special breed of people, they willingly take responsibility for another life and take care of them. I personally like pets as long as I can return them to the owner at the end of the day (or hour, depending on how annoying the pet is). I had to take care of a puppy for a week when Surabhi & Vinit were out of town and that experience was more than enough to confirm my belief in this matter. Others however feel differently and spend quite a lot of time and effort talking to the pets and some of them even pretend that the dog is talking back.

Now leveraging the power of AI there is a new app created that analyses & interprets the facial expressions of your pet. Folks over at the University of Melbourne decided to build an Convolutional Neural Networks based application called Happy Pets that you can download from the Android or Apple app stores to try on your pet. They claim to be able to identify the emotion the pet is feeling when the photo was taken.

While the science behind it is cool and a lot of pet owners who tried out the application over at Hacker News seem to like it, I feel its a bit frivolous and silly. Plus its hard enough for us to classify emotions in Humans reliably using AI so I would take the claims with a pinch of salt. The researchers themselves have also not given any numbers around the accuracy percentage of the model.

When I first saw the post about the app it reminded me of another article I had read a few days ago which postulated that ‘Too many AI researchers think real-world problems are not relevant’. At first I thought that this was an author trolling the AI developers but after reading the article I kind of agree with him. AI has a massive potential to advance our understanding of health, agriculture, scientific discovery, and more. However looking at the feedback AI papers have been getting it appears that AI researchers are allergic to practical applications (or in some cases useful applications). For example, below is a review received on a paper submitted to the NeurIPS (Neural Information Processing Systems) conference:

“The authors present a solution for an original and highly motivating problem, but it is an application and the significance seems limited for the machine-learning community.”

If I read this correctly then basically they are saying that this AI paper is for a particular application so its not interesting enough for the ML community. There is a similar bias in the theoretical physics/mathematics world where academics who talk about implementing the concepts/theories are looked down upon by the ‘purists’. I personally believe that while the theoretical sciences are all well & good and we do need people working on them to expand our understanding, at the end of the day if we are not applying these learnings/theorems practically they are of no use. There will be cases where we don’t have the know-how to implement or apply the learnings but we should not let that stand in the way of practical applications for things we can implement/use.

To quote a classic paper titled “Machine Learning that Matters” (pdf), by NASA computer scientist Kiri Wagstaff: “Much of current machine learning research has lost its connection to problems of import to the larger world of science and society.” The same year that Wagstaff published her paper, a convolutional neural network called AlexNet won a high-profile competition for image recognition centered on the popular ImageNet data set, leading to an explosion of interest in deep learning. Unfortunately, the disconnect she described appears to have grown even worse since then.

What do you think? Do you agree/disagree?

Transparent Solar Panels hit Record 8.1% Efficiency

Filed under: Emerging Tech,My Thoughts,Tech Related — Suramya @ 5:24 PM

Solar panels for electricity are awesome, however the major issue with deploying solar panels is that you need a lot of space for them. Although the efficiency of the panels has been going up reducing the space requirements but its still a non-trivial amount of space to generate enough power to be useful to power a house, Portable solar panels are well and good but they are slow and expensive. I tried to figure out a way to power my apartment via solar power but it wasn’t possible without having panels setup on the apartment roof.

Which is where the Transparent Solar panels come into play as they allow you to replace your existing windows for solar panel which would make them ideal for Apartments & office buildings. Because you don’t need extra space for the panels and just need to replace the windows. The transparent solar panels were created in 2014 by researchers at Michigan State University (MSU) however the efficiency of the panels was quite low compared to the traditional panels making it less productive and more expensive than the traditional panels so since then the race has been on to make the panels more efficient.

The researches from University of Michigan have made a significant break through in the manufacturing of color-neutral, transparent solar cells achieving 8.1% efficiency by using a carbon-based design rather than conventional silicon. The created cells do have a slight greenish tinge like sunglasses but for the most part appear to be usable as a window pane. More details are available in their release here.

The new material is a combination of organic molecules engineered to be transparent in the visible and absorbing in the near infrared, an invisible part of the spectrum that accounts for much of the energy in sunlight. In addition, the researchers developed optical coatings to boost both power generated from infrared light and transparency in the visible range—two qualities that are usually in competition with one another.

The color-neutral version of the device was made with an indium tin oxide electrode. A silver electrode improved the efficiency to 10.8%, with 45.8% transparency. However, that version’s slightly greenish tint may not be acceptable in some window applications.

Transparent solar cells are measured by their light utilization efficiency, which describes how much energy from the light hitting the window is available either as electricity or as transmitted light on the interior side. Previous transparent solar cells have light utilization efficiencies of roughly 2-3%, but the indium tin oxide cell is rated at 3.5% and the silver version has a light utilization efficiency of 5%.

The researchers are still working on improving the efficiency further and I am looking forward to the new breakthroughs in the field. Hopefully soon we will have panels efficient enough that I will be able to replace my apartment’s windows with Solar panel and break even in a reasonable amount of time. 🙂

Convert typed text to realistic handwriting

Filed under: Computer Related,Computer Software,Tech Related — Suramya @ 6:45 PM

There are some tools or projects that really don’t make any practical sense but are a lot of fun to use or just impressive in how they implement technology. The Handwritten.js project by ‘alias-rahil’ is one such project. Basically what it does is take any Plain Text document and convert it into a realistic looking handwritten page. I tried it out on a few sample documents (logs) and it worked great. The programs does coredump if you try converting a 5MB file, but other than that it worked as expected.

Below is a sample file with some quotes that I converted as a test :

* Mountain Dew and doughnuts… because breakfast is the most important meal of the day

* Some days you’re the dog; some days you’re the hydrant.

* He who smiles in a crisis has found someone to blame.

* Marriage is one of the chief causes of divorce

* Earth is 98% full…please delete anyone you can.

* I came, I saw, I decided to order take out.

* F U CN RD THS U CNT SPL WRTH A DM!

* Work hard for eight hours a day, and eventually you may become a
boss and be able to work twelve.

* Quitters never win, and winners never quit, but those who never quit AND never win are idiots.

* What’s the difference between a bad golfer and a bad skydiver?

A bad golfer goes, WHACK! “Damn.”
A bad skydiver goes, “Damn.” WHACK!

* Beware of the light at the end of the tunnel. It could be an oncoming train.

* A girl is like a road. The more curves she has the more dangerous she is!

* A woman who dresses to kill probably cooks the same.

The script is fast and didn’t take more than a few seconds to process the file and create a PDF file with the output. The output for my test run is as below:


Output generated by Handwritten.js

I did also try converting a word file with the software but it didn’t take the content of the file for the conversion, instead it converted the XML & Code from the file. One suggestion for improvement I have is to enhance the script to support word files. It would be awesome if it could also convert any of the diagrams, tables etc to look like they were drawn by hand.

Maybe if I have some time I will look into this and see how easy it is to enhance the script. But no promises as I have a ton of other things I need to take complete first. 🙂

Finally moved the Website & Blog to https

Filed under: Computer Tips,Tech Related,Website Updates — Suramya @ 12:02 PM

After spending way too much time avoiding the work due I finally configured both suramya.com & the Blog to be https by default. The setup was fairly simple, I added the certificate on the 1and1.com portal, then after a few mins I was able to access the site over https. In order to redirect http to https automatically I followed the following steps:

Auto Redirect to https in Apache

Configure .htaccess to force a redirect, you can also configure it in the Apache main configuration (under the virtualhosts directive) but since I don’t have root access and can’t modify it I updated the .htaccess config to do the same thing. Basically you need to add the following lines to .htaccess :

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.suramya.com/$1 [R,L]

Change www.suramya.com to your domain, else every visitor to your site will be sent to my site. Not that I will mind that, but you might. 🙂

Then I did the same thing for the blog with a small change, The .htaccess for the blog reads as the following:


RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.suramya.com/blog/$1 [R,L]

When updating the file, you need to ensure you put the changes outside the # BEGIN WordPress & # END WordPress as the content is dynamically generated and would be overwritten.

Updating all the urls in WordPress

After I made the changes above, I found that the site was being redirected to https but I was getting errors about mixed content on the page because all the URL’s/Images that I had uploaded to WP till now were saved as http and not https. So I had to change every URL in the blog from http to https and to be honest I wasn’t looking forward to doing this manually. I searched the web and found this site that had instructions on how to update the url’s using the WordPress commandline interface. From the blog directory you need to issue the following command:

wp search-replace http://www.suramya.com/blog/ https://www.suramya.com/blog/ --dry-run

This command does a dry run and tells you what all changes will be made and if everything looks ok, then you can run the above command again without the ‘dry-run’ call.

wp search-replace http://www.suramya.com/blog/ https://www.suramya.com/blog/

If all goes well you will get an output similar to the following:

Success: Made 3992 replacements.

That’s it. After running the command, the blog is completely on https and the security gods are happy :). Now I need to update all the URL’s on the main site to reference https instead of http and that is going to be painful. It will require a whole lot of script-fu to do it automatically as it will have to be a regex/awk or something similar. Maybe someone already did the work and posted the solution online. Alas that was not the case. I ended up manually updating the files since there were only about 20-25 of them. Opened all of them in the editor one-shot and then did a search & replace. Now both sites are coming up properly in https.

Updating the BIOS to address a AMD Ryzen bug

Filed under: Computer Related,Computer Software,Tech Related — Suramya @ 5:13 PM

Over the past few months I have been infrequently seeing the following warning message in the Terminal and had been ignoring it because apparently the fix was to update the BIOS and I didn’t have the patience/time to do the upgrade at that point in time:

WARNING: CPU random generator seem to be failing, disable hardware random number generation
WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffff 0xffffffff
WARNING: CPU random generator seem to be failing, disable hardware random number generation
WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffff 0xffffffff

Today I thought that I should fix the error, a bit of Google searching confirmed that I needed to update the BIOS because apparently there was a bug in the AMD Ryzen 3000 series processor that causes the onboard random number generator to always return 0xffffffff when asked to generate a Random number. Obviously getting the same number every time is not optimal even though Dilbert feels otherwise.


Random Number Generator in Accounting

AMD was notified about it last year and they released a BIOS update to fix the issue, however each Motherboard company had to validate and release the new BIOS which took time. The fix was to upgrade the BIOS and I really wasn’t looking forward to it as the last time I upgraded the BIOS it was a painful exercise involving floppy disks and cursing etc.

I looked up my BIOS version using the dmidecode command but that didn’t give me enough information to find the new BIOS version for my motherboard (‘ROG STRIX X570-E GAMING’). So I rebooted the computer and found the built in BIOS upgrade section under Tools. I decided to give it a try and see what options are available so I clicked on the Upgrade option and it gave me the option of connecting to the Internet and automatically downloading the latest version of the BIOS or installing it from a USB/Disk Drive. I selected the Network Install option and the system happily downloaded the latest version of the BIOS from the Internet and then gave me the option to Install the new version. I selected ‘Yes’ and the BIOS was upgraded.

The system had to reboot a few times for the upgrade to complete and there was a boot where the system played a bunch of beeps without anything coming up on the display which scared the life out of me but then it immediately rebooted and the display came back. After the upgrade completed I got a screen with a bunch of messages about BIOS settings needing to be reinitialized but when I went into the BIOS the settings were all there. So I rebooted and now all looks good and I don’t see any more weird error messages in the Console or the logs.

I am happy to see that the process to upgrade the BIOS is now so simple and I will be upgrading the BIOS more frequently going forward.

Thoughts on Cybercrime in the Covid world

Filed under: Computer Security,My Thoughts,Tech Related — Suramya @ 1:07 PM

The Cyber Security industry has seen a massive boost during the current pandemic, with users working remotely for the first time and permissions granted on the fly the Security teams in the enterprise have been working round the clock to ensure critical data and systems are secure. But due to the general chaos of Covid combined with the need to keep businesses running there are systems that have been less than optimally configured.

All this gives us the impression that the Cybercrime world must be thriving in the current environment. But apparently that is not always the case, the Cambridge Cybercrime Centre has released a series of reports on how the Pandemic has impacted cybercrime. The reports are a fascinating read as they show how even the criminals are facing hardships due to the pandemic. For example, below is an extract from the report on the impact on International drug trade due to the shipping disruptions caused by lockdowns.

“The initial wave of COVID lockdowns in China caused substantial disruption to international shipping,compounded by the subsequent lockdowns in the rest of the world. Despite their ‘online’ character, drugscryptomarkets (online markets for legal and illegal drugs which are accessed securely through anonymitynetworks such as Tor) are reliant on the postal and shipping services for the delivery of drugs and precursorsto suppliers and end users. We have observed, in our scraped datasets of illicit online forums and discussionboards, evidence of significant disruption of these pathways, and a range of effects on these illicit markets.At the initial peak of lockdown measures, shipping times (especially in international routes which passedthrough China) were being routinely delayed by up to three months (as reported in cryptomarket discussions).This caused significant friction to international orders for postal drug delivery, with many dealers reportingthat they were switching to orders within the same nation only, and others struggling to source supply.”

Brian Kerbs from Kerbs on Security wrote a comprehensive article on How Cybercriminals are Weathering COVID-19 and its worth a read as well.

But apparently a number of criminal reshipping services are reporting difficulties due to the increased wait time when calling FedEx or UPS (to divert carded goods that merchants end up shipping to the cardholder’s address instead of to the mule’s). In response, these operations are raising their prices and warning of longer shipping times, which in turn could hamper the activities of other actors who depend on those services.

That’s according to Intel 471, a cyber intelligence company that closely monitors hundreds of online crime forums. In a report published today, the company said since late March 2020 it has observed several crooks complaining about COVID-19 interfering with the daily activities of their various money mules (people hired to help launder the proceeds of cybercrime).

The same is happening for real world crime also, Jani was telling me about this article on Goa where the local drug dealers are out of job because no tourists are visiting so they all are now selling fish to survive.

Well this is all for now. Will write more later.

Interested in Coding using emoji’s? Check out emojicode

Filed under: Computer Software,My Thoughts,Tech Related — Suramya @ 12:12 PM

I am not the most fervent fan of emojis in the world and for the most part I have gone through the last 20+ years with about 3-4 emojis that I use on a regular basis. But I know people who communicate wholly using them and while I am ok with folks using them in personal communications I dislike them immensely in professional communications (except for the occasional smiley face). However not everyone agrees with me and there have been books published in the past using just Emoji’s and now there is a programming language that is written entirely in emoji.

Emojicode, which first appeared as a Github project back in 2016 has been around for a while now and has a fairly strong following in the tech world. I realize that I sound like one of the old men screaming ‘Get off my lawn’ but I really don’t understand why anyone would want to code in a language that uses emoji’s to define text as a serious programming language. As a joke it would be fun to learn but I can’t really imagine coming in to work one day and writing code using Emojocode for a work project.

Here’s an example of the “Hello World” program written using Emojicode.


Hello World using Emojicode

If you want to learn coding in Emojicode, you can check out their impressive documentation or do a Code Academy course on the language. Emojicode is open-source, so you can also contribute to the development via their GitHub repository.

Yes, learning new programming languages is cool, but I don’t think I will be spending the effort to learn Emojicode anytime in the near future.
