Abstract
One embodiment provides a system for efficiently and securely encrypting, transmitting, and decrypting video data, including selective encryption of image frames. During operation, the system obtains by a content-transmitting device, an image frame which is used to form a video stream. In response to determining that the image frame satisfies a predetermined condition for encryption, the system encrypts the image frame based on an encryption algorithm. The system encapsulates the encrypted image frame based on encapsulation information. The system includes encryption identification information for the image frame in the encapsulation information.
