Abstract: A data encryption method includes: acquiring target data to be encrypted of a target object and object information corresponding to the target object, the object information including at least one of a face image or an audio signal of the target object; encrypting an object feature corresponding to the object information according to a reference public key, and determining the encrypted object feature as a safety factor of the target data; and encrypting the target data based on the safety factor, to obtain encrypted data corresponding to the target data.

Abstract: Disclosed are a picture encryption method and apparatus, a computer device, a storage medium and a program product. The method includes: acquiring N pictures having a time sequence, N being an integer equal to or greater than 2; performing feature extraction on the N pictures to acquire a picture feature of each of the N pictures; successively performing target prediction on the N pictures according to the time sequence to obtain prediction information of the each of the N pictures, the target prediction referring to a prediction on the each of the N pictures based on status information, and the status information being information which is updated based on picture features of pictures that have been predicted; and encrypting the N pictures based on the prediction information of the each of the N pictures.

Abstract: A speech recognition method and apparatus, and a storage medium are provided. The method includes: acquiring, by a digital signal processor (DSP), audio data; performing, by the DSP, fuzzy speech recognition on the audio data; waking up a central processing unit (CPU) in a dormant state if a fuzzy speech recognition result indicates that that a wakeup word exists in the audio data. The method also includes: reading, by the CPU, data corresponding to the wakeup word in the audio data from the DSP, to obtain wakeup data; determining, by the CPU, whether the wakeup word exists in the audio data by performing speech recognition on the wakeup data; if the wakeup word exists, performing, by the CPU, semantic analysis on the audio data; and if the wakeup word does not exist, determining, by the CPU, that the fuzzy speech recognition result is incorrect and entering the dormant state.
