Brain shape as a biometric
TL;DR: In this paper, a method, system, and program product for identifying an individual using biometric data based on the individual's brain is presented, which includes constructing a biometric signature based on at least one of: features within a 2D scan of the individual brain and a difference in features between at least two 2D scans of brain.

PPDL - Privacy Preserving Deep Learning Using Homomorphic Encryption
TL;DR: This work explores a class of privacy preserving machine learning technique called Fully Homomorphic Encryption in enabling CNN inference on encrypted real-world dataset and achieves the end goal of enabling encrypted inference for binary classification on melanoma dataset using Cheon-Kim- Kim-Song (CKKS) encryption scheme available in the open-source HElib library.

Back to the future: A fully automatic method for robust age progression
TL;DR: This paper proposes a novel method for robust and automatic face progression in totally unconstrained conditions that outperforms state-of-the-art age progression methods and improves matching accuracy in a face verification protocol that includes age progression.

Fusing biographical and biometric classifiers for improved person identification
TL;DR: It is shown that a likelihood ratio based method for score level fusion of the biometric and biographical classifiers results in high accuracy identification as compared to using only theBiometric classifiers or the biographicalclassifiers.
