A potential security problem in frequency domain video encryption is that some trivial information such as the distribution of DCT coefficients may leak out secret. To illuminate this problem, we performed a successful attack on video using the distribution information of DCT coefficients. Then, according to the weak points discovered, a novel video encryption algorithm, working on run-length coded data, is proposed. It has amended identified security problems, while preserving high efficiency and the adaptability to cooperate with compression schemes.
