Multimodal Biometrics for Enhanced Mobile Device Security

This post is a reference to a contributed article that I helped to co-author which was recently published in Communications of the ACM, Vol. 59 No. 4, Pages 58-65. The article, which I worked on while in graduate school, describes the advantages of using multimodal biometrics to secure mobile devices such as cell phones and tablets. An implementation for the Android OS of such a multimodal biometric system is presented along with results and a conclusion. Please find the article at this link, if you wish to read more.

Eigenfaces versus Fisherfaces on the Faces94 Database with Scikit-Learn

In this post, two basic facial recognition techniques will be compared on the Faces94 database. Images from the Faces94 database are 180 by 200 pixels in resolution and were taken as the subjects were speaking to induce variations in the images. In order to train a classifier with the images, the raw pixel information is extracted, converted to grayscale, and flattened into vectors of dimension . For this experiment, 12 subjects will be used from the database with 20 files will be used per subject. Each subject is confined to a unique directory that contains only 20 image files.
