There is a verification application arranged to interact with other applications on an electronic device, the electronic device having a processor, a memory and an operating system controlling operation of the verification application and the other applications on the processor using arbitrary memory locations, where the other applications are enabled to call the verification application to securely determine authenticity of a user of the electronic device. The verification application is arranged to receive verification data for secure determination of authenticity of the user; and provide, upon a call from any of the other applications and a match between the verification data and a verification reference, a trust token to the calling application. A method, electronic device and computer program are also disclosed.

Verification application, method, electronic device and computer program

There is provided a method of storing a set of biometric data templates, which emanates from a biometric object, among a plurality of biometric data templates, wherein each biometric data template comprises biometric data from only a part of a biometric object. The method comprises aligning biometric data templates with each other in view of the biometric object of the plurality of biometric data templates which comprises partially overlapping biometric data with at least one other biometric data template; determining the set of biometric data templates to be stored; and storing the set of biometric data templates. The determining of the set of biometric data templates to be stored comprises assigning a matrix of cells covering at least partially the aligned biometric data templates; determining, for each of the aligned biometric data templates, cells comprising distinguishable biometric data; and determining a combination of biometric data templates which comprises an amount of cells comprising distinguishable biometric data which fulfil a predetermined criterion. A method of biometric matching is also disclosed, and also a biometric matching apparatus and a computer program.
