Kiran Bylappa Raja defended his thesis

Kiran Bylappa Raja defended his thesis titled “Robust Biometric Verification based on the Eye Region - Algorithms for Visible Spectrum Image Data”.

Popular mobile banking and e-commerce applications like Google Wallet, Apple Pay and Ali Pay have resulted in the use of smartphones for secure access of services via biometric data captured from an embedded sensor.

Now the improved optics on smartphones have been explored for biometric data capture in a contactless manner as well. This can be used for various secure authentication applications. Specifically, the applications are exploring face, periocular and iris characteristics for smartphone-based authentication using the embedded camera.

Raja presented a set of robust algorithms and techniques to use iris, periocular and face data for authentication applications when captured from smartphones in the visible spectrum. He has improved the biometric systems by detecting spoofing attacks and thereby making the authentication applications trustworthy on smartphones.

Raja’s Principal supervisor was Professor Christoph Busch, NTNU in Gjøvik and secondary supervisor was Dr. Raghavendra Ramachandra, NTNU in Gjøvik.
