Abstract

Abstract

  • 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 do main without decryption preserves the confidentiality of the content.In addition, it is more efficient without decryption followed by data hiding and re-encryption.

  • In this paper, a novel scheme of data hiding directly in the encrypted version of H.264/AVC video stream is proposed, which includes the following three parts, i.e., H.264/AVC video encryption, data embedding, and data extraction.

  • By analyzing the property of H.264/AVC codec, the codewords of intraprediction modes, the codewords of motion vector differences, and the codewords of residual coefficients are encrypted with stream ciphers. Then, a data hider may embed additional data in the encrypted domain by using codeword substitution technique, without knowing the original video content.


Existing system

Existing System

  • A digital watermarking algorithm for copyright protection based on the concept of embed digital watermark and modifying frequency coefficients in discrete wavelet transform(DWT) domain is presented.

  • We embed the watermark into the detail wavelet coefficients of the original image with the use of a key.

  • This key is randomly generated and is used to select the exact locations in the wavelet domain in which to embed the watermark.

  • Original unmarked image is not required for watermark extraction.

  • The performance of proposed watermarking algorithm is robust to variety of signal distortions and noises.


Proposed system

Proposed System

  • Sender sends an information in the form of video using mp4 files to the receiver.

  • Sender also wants to send secret information along with this video source.

  • Receiver only able to view this secret information in the form of decompressed content.

  • Rivest Block based Ciphering Algorithm and Data Hiding in Encrypted H.264/AVC Video ,codeword substitution techniques involved together and hide the secret content in this video source.

  • Encoded format of this content is compressed and the compressed source send to the receiver.
