Abstract

The invention relates to methods and devices for updating encrypted biometric data of a user at a trusted network node. In an aspect of the invention a method performed by a first client device (100)is provided of updating encrypted biometric data of a user (200), the encrypted biometric data to be updated having been previously captured by the first client device (100)and registered at a trustednetwork node (300).

Description

technical field [0001] The present invention relates to a method and a device for updating encrypted biometric data of a user at a trusted network node. Background technique [0002] In prior art multi-user biometric authentication systems, biometric data needs to be captured at one client device to enable identification of a user based on biometric data such as fingerprint recognition, while making biometric data available for another biometric Authentication of certified devices. [0003] However, since raw biometric data templates are very sensitive from a security perspective, it is critical to ensure that raw biometric data is only available on trusted biometric reading devices and that biometric data never leaves such secure computing environments. important. [0004] Biometric technology allows for effective end-user identification without requiring end-users to remember usernames or passwords or to carry specialized hardware tokens. However, while the privacy impa...
