Problems solved by technology

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 compromised on all other systems and when the biometric data is used
Simply encrypting the biometric data will not solve this problem as the original biometric data must be available at the remote location during verification

Abstract

In a first aspect of the invention there is provided a method performed by a client device (100) of enrolling biometric data of a user (200) of the client device with a network node (300) over a secure communication channel. The method includes capturing (S101) biometric data of a user (200), transforming the biometric data using a first feature transformation key shared with any other client device (500) at which the user (200) is to be authenticated Converting (S102) into a first set of converted biometric data, generating (S103) a second feature conversion key, and converting (S104) the biometric data into a second set of converted biometric data using the second feature conversion key . The method further comprises encrypting (S105) the first set of transformed biometric data and the second set of transformed biometrics using an encryption key shared with the biometric data verification node (400) on which the user (200) is to be authenticated data, encrypting (S106) the second feature transformation key using an encryption key shared with the network node (300) at which the first set of transformed biometric data and the second set of transformed biometric data are to be registered, and sending to The network node (300) submits (S107) an enrollment request comprising the encrypted first set of converted biometric data, the second set of converted biometric data, the encrypted second feature conversion key and user profile data.

Description

technical field [0001] The invention relates to a method and a device for registering biometric data of a user with a network node through a secure communication channel. The invention further relates to a method and a device enabling authentication of a user based on registered biometric data. Background technique [0002] Biometric-based identification is a user-friendly way to securely authenticate human users. A major problem with biometric data when using it for identification purposes in a distributed system is that the template biometric data must be available at a node in the computer system that identifies 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...
