Secret credentials are indispensable in the Internet-driven life. Text passwords/PINs are still the most used form of secret credentials. Biometrics is being promoted for authenticating the digital identity of the humans with text passwords/PIN as a fallback system. Text passwords seem insufficient but are not harmful.

Biometrics is insufficient and appears to be harmful in terms of data breach/stealing and spoofing. What can be a viable solution in this crisis situation?

Debesh Choudhury rejoins me on the Tech Talks Daly Podcast.

Debesh is a hardcore researcher and innovator with 24+ years of hands-on experience in defense research and information security. He also got 16+ years of experience in teaching electronics and communication engineering in the higher education arena.

Besides having a Ph.D. from Indian Institute of Technology, Bombay, India, he also enjoyed his two years postdoctoral stint at the University of Electro-Communications, Tokyo, Japan. Debesh was fortunate to have collaborated with celebrated American Scientist late Prof. H. John Caulfield. In 2011, they invented a new direction “Artificial Color Perception using Microwaves.”

Debesh worked on 3D shape sensing and recognition for quite some time. His method paved down a way for 3D human face recognition. He also developed an asymmetric cryptosystem for privacy protected biometric security.

Since leakage of biometric databases can cause permanent damage to the citizens' privacy and security, and also biometrics is less reliable than text passswords, Debesh and a group of researchers are proposing to have a sustainable digital identity platform using a non-text graphical password system.

Debesh has formed a LinkedIn group "Identity Crisis: The Future of Password Security" to critically explore the field and find a sustainable identity solution.
