摘要

A biological recognition technology-based mobile payment device, a method and apparatus, a computer program and a recording medium are disclosed. The mobile payment device comprises a biological information recognition application and a general payment Trusted Application (TA) operating in a Trusted Execution Environment (TEE), wherein the general payment TA is configured to: be called by multiple third party payment applications; receive a call request from a third party payment application; based on the call request, determine target content to be encrypted and an encryption parameter for performing encryption; acquire a biological information recognition result from the biological information recognition application; encrypt the target content according to the encryption parameter and the biological information recognition resu and return an encryption result to the third party payment application, so that the third party payment application performs a payment-related operation based on the encryption result.
