2results about How to "Avoid illegal acquisition" patented technology

This application relates to a data encryption method, a risky data processing method, an apparatus, a computer device, and a storage medium. The method includes: acquiring application source code data; compiling the application source code data to obtain first application compiled data; replacing the signature encryption public key in the first application compiled data with a simulated public key to obtain second application compiled data. If a data encryption request is received, the method acquires the data to be processed corresponding to the data encryption request, restores the second application compiled data to the first application compiled data, and performs encryption and signature processing on the data to be processed based on the signature encryption public key in the first application compiled data to obtain encrypted signature data. This method can reduce the risk of leakage of the signature encryption public key, as well as information leakage and resource loss to the platform and users, and improve the efficiency of information security protection.

This invention discloses a digital key sharing method, apparatus, smart device, and medium. The method includes: a vehicle owner's device identifying a target friend's device based on an NFC channel and establishing a near-field secure communication channel with the target friend's device; detecting whether preset sharing confirmation conditions are met; and if the preset sharing confirmation conditions are met, sending shared key information to the target friend's device through the near-field secure communication channel; the shared key information carries application information for retrieving the shared key, and the target friend's device executes a preset shared key retrieval process according to the application information. This invention achieves digital key sharing through near-field interaction, offering high security and convenient operation, and can also provide users with a refreshing sharing experience through animated feedback.
