Biological Recognition Technology-based Mobile Payment Device Method and Apparatus

摘要

The present invention relates to a mobile payment device, method and apparatus based on biometric technology and belongs to the field of mobile payment technology. The mobile payment device includes a biometric information identification app and a general payment TA operating in TEE; The general payment TA is provided so that it can be called from a number of third party payment apps, receives a call request of a third party payment app, determines a target content that needs to be encrypted based on the call request, Acquires the biometric information identification result in the biometric information identification app, encrypts the target content based on the encryption parameter and the biometric information identification result, and returns the encryption result to the third party payment application, So that the settlement-related operation can be executed based on the result of the encryption. Accordingly, a plurality of third party payment applications can realize a common payment TA to be shared, and on the other hand, it is advantageous to reduce the signing cost. On the other hand, a malicious TA of the third party payment application is installed The safety risk of TEE can be reduced.
