INTRODUCTION

Data hiding and watermarking in digital images and raw video have wide literature.

This paper targets the internal dynamics of video compression, specifically the motion estimation stage.

The method is implemented and tested for hiding data in natural sequences of multiple groups of pictures and the results are evaluated.

EXISTING SYSTEM

We find that in most existing approaches, the choice of embedding positions within a cover image.

DISADVANTAGES: It requires lot of overhead to hide few bits of information.

The entire data sometimes doesn’t fit in the image. .

PROPOSED SYSTEM

We expand the LSB matching revisited image Steganography and propose an edge adaptive scheme .

Which can select the embedding regions according to the size of secret message and the difference between two consecutive pixels in the cover image.

ADVANTAGES

The proposed method is found to have lower distortion to the quality of the video and lower data size increase.

When the embedding rate increases, more edge regions can be released adaptively for data hiding by adjusting just a few parameters.

ARCHITECTURE

MODULES

Image Steganography Analysis the image Data hiding through image

Video Compression

Motion Vector of Video

IMAGE STEGNOGRAPHY

Analysis the image

We have chosen this stage because its contents are processed internally during the image encoding/ decoding.

Admin choose the image and has to be entered the text, image or shape, the admin has the permission to alter the image as he like; this is the first process of analyzing.

Data hiding through image

Admin encrypt the key and embed in the image and

later on that will be embeded in a video file.

Video CompressionAdmin has to be choose one video file along with one key,

both will be compression and create one encoding key send to the member.

Motion Vector of Video

Authenticated person after taking the privacy key he has only the authority what are the video which was sent by Admin.

The member can see the video in our application, in that video it can detect the motion vector.

CONCLUSION

We proposed a new data-hiding method in the motion vectors

of MPEG-2 compressed video.

This technique is very effective in security of a data and also

this technique hides large amount of data with the help of

Compression feature.
