Big Data Biometrics Processing

A Case Study of an Iris Matching Algorithm on Intel Xeon Phi

Xueyan Li and Chen Liu

Abstract

With the rapidly expanded biometric data collected by various sources for identification and verification purposes, how to manage and process such Big Data draws great concern. On one hand, biometric applications normally involve comparing a huge amount of samples and templates, which has strict requirements on the computational capability of the underlying hardware platform. On the other hand, the number of cores and associated threads that hardware can support has increased greatly; an example is the newly released Intel Xeon Phi coprocessor. Hence, Big Data biometrics processing demands the execution of the ...
