Indian Institute of Technology, Ropar and Monash University, Australia have developed a unique detector named ‘FakeBuster’

Researchers at the Indian Institute of Technology, Ropar in Punjab and Monash University, Australia have developed a unique detector named ‘FakeBuster’ to identify imposters attending a virtual conference without anybody’s knowledge. It can also find out faces manipulated on social media to defame or make a joke of someone.

In the present pandemic scenario when most of the official meetings and work is being done online, this standalone solution enables a user (organizer) to detect if another person’s video is manipulated or spoofed during a video conferencing. That means the technique will find out if some imposter is attending a Webinar or virtual meeting on behalf of one of your colleagues by morphing his image with his own. 

 “Sophisticated artificial intelligence techniques have spurred a dramatic increase in manipulation of media contents. Such techniques keep evolving and become more realistic. That makes detection difficult which could have far reaching security implications”, said Dr. Abhinav Dhall, one of the key members of a four-man team that developed the ‘FakeBuster’. “The tool has achieved over 90 per cent accuracy” assures Dr. Dhall. The other three members include Associate Prof. Ramanathan Subramanian and two students Vineet Mehta and Parul Gupta.

A paper on this technique – FakeBuster: A DeepFakes Detection Tool for Video Conferencing Scenarios – was presented in the 26th International Conference on Intelligent User Interfaces, in the USA, last month.  Dr. Dhall said that the usage of manipulated media content in spreading fake news, pornography and other such online content has been widely observed with major repercussions. He said such manipulations have recently found their way into video-calling platforms through spoofing tools based on transfer of facial expressions. These fake facial expressions are often convincing to the human eye and can have serious implications. These real time mimicked visuals (videos) known as ‘Deepfakes’ can even be used during online examinations and job interviews. 

This software platform is independent of video conferencing solutions and has been tested with Zoom and Skype applications. The Deepfake detection tool-‘FakeBuster’ works in both online and offline modes. Since the device can presently be attached with laptops and desktops only “we are aiming to make the network smaller and lighter to enable it to run on mobile phones/devices as well”, informed Associate Prof. Subramanian. He said the team is working on using the device to detect fake audios also.

The team claims that this software platform ‘FakeBuster’ is one of the first tools to detect imposters during live video conferencing using DeepFake detection technology. The device has already been tested and would hit the market soon.

 

IIT Ropar develops portable tech-traditional eco-friendly mobile cremation system

Indian Institute of Technology, Ropar has developed a prototype of a moveable electric cremation system which claims to be using first of its kind technology that involves smokeless cremation despite using wood. It uses half of the wood otherwise required for the cremation and still is eco-friendly because of the technology that uses the combustion air system.

It is based on wick-stove technology in which the wick when lighted glows yellow. This is converted into smokeless blue flame with the help of a combustion air system installed over the wicks. IIT Professor Dr Harpreet Singh, Dean, Industrial Consultancy and Sponsored Research and Industry Interaction (ICSR&II) who has developed the system said that the cremation system or incinerator heats up at 1044 degree Celsius which ensures complete sterilization.  

The cart-shaped incinerator has wheels and can be transported anywhere without much efforts. The cart is equipped with combustion air for primary and secondary hot air system. “The disposal of the body is completed within 12 hrs including cooling time as against 48 hours required in the normal wood-based cremation”, Prof. Harpreet added. Use of less wood can also reduce the carbon footprint by half. He said it requires less cooling time in the absence of refractory heat storage. It has stainless steel insulation on both sides of the cart for no heat loss and less wood consumption. It also has a tray beneath for easy removal of ashes.

He said that he has adopted a tech-traditional model for cremation as it also uses wood. That has been done keeping in view our beliefs and traditions of cremating on wood pyre. Keeping in view the present pandemic situation “if this system can be adopted, may provide respectable cremation to the near and dear ones of those who cannot afford the financial burden of arranging wood”, said Harjinder Singh Cheema, MD, Cheema Boilers Ltd. who has made the prototype. He said that since this is portable, it can be taken to any place with the permission of the concerned authorities. This will also help people to avoid space crunch in crematoriums as is the case in present context.
