Abstract: Nowadays everywhere we are facing problem of copyright through online or any other sites so to avoid copyright for specially video here is new method by using codeword mapping algorithm. 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 this algorithm we are defined three different phases to protect from copyright , first one is we need to take AVI video then encrypted using H.264/AVC encrypted scheme then second phase is we need to hide secret key to that encrypted video ,this will be done by authority person he will be not aware of the original video itself so here we can say video is secured ,after once secret key is inserted to encrypted video at receiver he can extract video by two method ,next comes in third phase first user can extract video then get back hidden key or first get hidden key then extract original video .This module will give very low encoding bit rate compare to other format and video quality will remain same at the receiver .we can apply this for any real time application where we need video security purpose like patient personal information can be secured in video and military purpose to send secret information through video.
