Problems solved by technology

When biometric data is used for identification purposes in a distributed system, one of the main problems associated with biometric data is that template biometric data must be available at nodes in the computer system that are supposed to identify the end user
Such a solution is highly susceptible to compromise of the original biometric data, and compromised data on one system can lead to a situation where the same biometric data is also compromised on all other systems using the biometric data
Simply encrypting the biometric data will not solve the problem since the raw biometric data must be available at the remote location during authentication

Abstract

The invention relates to methods and devices for enabling authentication of a user based on biometric data. In an aspect of the invention, a method performed by a client device (100) of enabling authentication of user (200) of the client device (100) with a network node over a secure communication channel based on biometric data is provided. Further, an enrollment set is provided by the client device, which is used for the authentication, where said enrollment set comprises a fuzzy vault, which contains registered biometric data and a first secret key. The enrollment set also comprises transformed non-invertible biometric data, a second secret key and a secret random number.

Description

technical field [0001] The present invention relates to methods and devices capable of authenticating a user of a client device over a secure communication channel based on biometric data. Background technique [0002] Biometric-based identification is a user-friendly way of securely authenticating human users. When using biometric data for identification purposes in a distributed system, a major problem with biometric data is that template biometric data must be available at nodes in the computer system that are supposed to identify the end user. This poses a major security design challenge in distributed computer systems, as this typically requires raw, clear-text biometric data to be stored at a central node and distributed across the system. Such solutions are highly susceptible to compromise of the original biometric data, and compromised data on one system can lead to a situation where the same biometric data is also compromised on all other systems that use the biome...
