An improved scheme for data hiding in encrypted H.264/AVC videos

•The embedding is done on encrypted H.264/AVC data without knowing the decryption key.•The paired code-word substitution and multiple-base notational system are exploited.•Both encryption and data embedding keep the bit-rate intact.•Data extraction can be carried out either in encrypted or decrypted...
