We revisit the high-dimensional content identification with lossy recovery problem (Tuncel
and Gündüz, 2014) and establish an exponential strong converse theorem. As a corollary of …

Past works on remote lossy source coding studied the rate under average distortion and the
error exponent of excess distortion probability. In this work, we look into how fast the excess …

Abstract Robust Principal Component Analysis (RPCA) aims at recovering a low-rank
subspace from grossly corrupted high-dimensional (often visual) data and is a cornerstone …

In the digital authentication system, the emerging technology is fingerprint authentication,
which have been concentrated more attraction towards security and control. Existing …

In a system that performs both encryption and lossy compression, the conventional way is to
compress first and then encrypt the compressed data. This separation approach has been …

Speech is considered as one of the most efficient and effective way to communicate with
each other. However, a deception is a very common phenomenon in speech …

India being digitized through digital India, the most basic unique identity for each individual
is biometrics. Since India is the second most populous nation, the database that has to be …

The adoption of biometric-based authentication mechanism has been already initiated a
decade back but still in real-life we get to see usage of only unimodal biometrics. Out of all …
