Review on Real Time Data Encryption in H.264/Avc Video Streams by Exploiting IPCM Microblocks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
In daily life, there is an increase in the use of multimedia applications such video conferencing, video telephony, stream video/audio online etc. For the purpose of highly secure data transmission safely, there is a requirement of encryption of digital data. In this paper, we studied the various methods of data encryption technique, and find out the best method for the secured data transmission. H.264 is well-known compression standard technique for original raw video. Data hiding using general techniques will not perform under this scheme. We present a data hiding approach in IPCM block. Where these IPCM encoded macroblocks are modified in order to hide the desired data. Generally in video encryption, the numbers of IPCM blocks generated are very less. A method is presented to increase the number of IPCM blocks generated in H.264/AVC algorithm, by which more data can be hidden. It is a blind data hiding approach, i.e. the message can be extracted directly from the encoded stream without the need of the original host video.
