“…In our framework, we have followed the adaptation approach described in [1] where temporal adaptation of H.264 is performed dynamically and directly from the compressed H.264 bitstream applying the MPEG-21 gBSD. Here, we make use of the gBSD to identify the segments into which the authentication bits can be embedded.…”

“…In our previous works, we utilized MPEG-21 gBSD to perform temporal adaptation [1] and encryption [2] of the H.264 video stream in compressed domain. In this paper, we present an authentication technique which utilizes gBSD to select the marking space from a video content in the compressed domain.…”

“…In this paper, we present an authentication technique which utilizes gBSD to select the marking space from a video content in the compressed domain. The technique presented here requires low computational effort, low processing time and works on top of the adaptation framework [1] because no cascaded decompression-recompression operation is performed. The resulting video conforms to H.264 bitstream syntax structure and can be decoded by a standard decoder.…”

While trivial research has been conducted in watermarking and authentication of H.264 video in recent years, most techniques require cascaded operations within a video adaptation scenario. In this paper, we propose an authentication scheme for adapted H.264 video content to detect integrity at the receiver's side without the need for cascaded operations. The proposed scheme utilizes MPEG-21 gBSD for hard authentication of H.264 video in the compressed domain and does not necessitate any cascaded decompression and recompression. The design uses contentbased authentication which is derived from a hash value. The authentication data is embedded as a fragile watermark, and the marking space is selected during the adaptation process of the H.264 video by parsing the gBSD. The authentication information is embedded in already encoded videos during adaptation. Proof of concept and performance evaluation is also presented.

“…Users seek the ability to adapt multimedia content to suit each user's needs, thereby maximizing the user's experience. To deal with this changing role of users, and to ensure universal multimedia access (UMA), it is only feasible to adapt the multimedia content to fit the environment and not vice versa [5].…”

“…One of such solutions is instantaneous transcoding. This involves an intermediary node located between the multimedia provider and the user performing instant encoding/decoding operations based on each user's preference [5]. Needless to say, this solution is rather cumbersome, cost intensive and impractical.…”
