Picture encryption method and apparatus, computer device, storage medium and program product

A device for picture encryption, the device comprising a memory for storing computer instructions and a processor in communication with the memory, wherein, when the processor executes the computer instructions, the processor is configured to cause the device to:

• acquire N pictures having a time sequence, N being an integer equal to or greater than 2;
• perform feature extraction on the N pictures to acquire a picture feature of each of the N pictures;
• successively perform 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
• encrypt the N pictures based on the prediction information of the each of the N pictures.

A non-transitory storage medium for storing computer readable instructions, the computer readable instructions, when executed by a processor, causing the processor to:
