Abstract: The present disclosure relates to a mobile payment method and device based on a near field communication function, which can seamlessly switch between a fingerprint verification mode and a non-fingerprint verification mode. The mobile payment method according to the present disclosure includes the following steps: executing a non-contact protocol initialization process between a mobile payment terminal and an external device by the mobile payment terminal; receiving a selection command from the external device by the mobile payment terminal, the selection command designating a non-contact application; determining, by the mobile payment terminal, whether the designated non-contact application supports a fingerprint verification mode; determining, by the mobile payment terminal, whether the designated non-contact application has passed the fingerprint verification, if the fingerprint verification mode is supported; and running the designated non-contact application by the mobile payment terminal to execute a payment operation, if the designated non-contact application has passed fingerprint verification or does not support the fingerprint verification mode, wherein the execution of the non-contact protocol initialization process is independent of the execution of the fingerprint verification process.

Abstract: A method for authorizing a blockchain data access on a blockchain platform includes: obtaining from a third-party institution a data access request containing a user ID of data access, a data scope, and a random number of a signature, which is generated by the third-party institution after receiving a random number sent by a client terminal and signing on the received random number; performing a verification on the random number of the signature and the data scope; and after the verification is passed, sending data ciphertext corresponding to the user ID to the third-party institution, such that the third-party institution decrypts the data ciphertext using a data secret key sent by the client terminal.

Abstract: Embodiments of the present invention disclose an application management method for terminals, including: after receiving the application download request sent by the terminal, the application server sends the corresponding application installation package to the terminal. Then, the first verification message sent by the terminal is received, and the first verification message is generated by the terminal according to the content of the received application installation package. After determining that the first verification message is consistent with a stored second verification message, the application server sends an permit-to-install message to the terminal, so that the terminal installs the application according to the received application installation package. Because the application server determines the legitimacy of the application package, it does not need the terminal to verify by using the certificate, thereby reducing the certificate work management for the terminal and improving the efficiency of application installation.

Abstract: The present invention relates to a method for access control of a multimedia system to a secure operating system and a mobile terminal for implementing the method. The method includes the steps of: initiating an application access request for selecting a trusted application from a client application of a multimedia system to a secure operating system; making a decision as to whether the client application is a malicious application, and if not, proceeding to a next step, if yes, returning Selection Failure to the client application and performing an interrupt handling; sending the application access request from the multimedia system to the secure system; and acquiring, at the secure operating system, the trusted application based on the application access request and returning the trusted application to the multimedia system. The malicious accesses initiated by a malicious application to a trusted application in a securing operating system can be prevented without switching between systems, and the problem that a trusted application cannot be accessed due to malicious access can be avoided.
