Biometric Template Security Using Visual Cryptography

WitrynaVisual cryptography enables to derive from an image two shares that give separately no information on the original image while leading back to the image by superimposition of the shares. In this work, we apply this technique to fingerprint features for enabling an alignment of a reference and a fresh images. The idea is to use an encrypted share … Witryna13 kwi 2024 · Security of medical images over an unsecured channel is a challenging task, and for this, several methods have been designed recently.
