Digital video sometimes needs to be stored and
processed in an encrypted format to maintain security and
privacy. For the purpose of content notation and/or tampering
detection, it is necessary to perform data hiding in these
encrypted videos. In this way, data hiding in encrypted domain
without decryption preserves the confidentiality of the content.
In addition, it is more efficient without decryption followed by
data hiding and re-encryption.
