Verification application, method, electronic device and computer program

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,

• wherein the verification application is further 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;
• wherein the verification data comprises a biometric sample and the verification reference comprises a biometric reference;
• wherein the verification application is arranged to be paired with at least one of the other applications by mutually exchanging at least one of
• an application signature,
• a cryptographic key or keys,
• a password, and
• a shared secret;
• and
• wherein the provision of the trust token is only performed when the verification application and the one of the other applications providing a call to the verification application are properly paired.
