We describe an efficient access control method for digital videos that controls access to video frames based on one-way hash functions. The method offers effective key management and delivery as well as conventional scalability-aware access control methods for coded still images. It uses hash chain-based key generation, thereby limiting the number of managed keys to one, and the user receives only one key as well. This method controls access to a video sequence based on frame rates, and it is applicable to access control of videos based on movie ratings. For access control with two controlled subjects, our method reduces the number of keys to the theoretical lower limit.
