Data Hiding Using Block Based Mosaic Images in Video
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In today’s modern world the digital technologies have helped peoples to exchange data on large due to availability of fast internet connectivity it has become very easy to exchange data. The security, integrity and reliability of data are crucial aspect behind this exchange process. In this paper we purpose a new method for securely transmission of image over the medium using Block based image mosaicing in video technique, which transforms automatically a given large-volume secret image into a secret-fragment-visible mosaic image of the same dimension. The mosaic image (video) looks similar to the selected source image (Target image), which is one of the frame of the video, and may be used as camouflage of the secret image. This is yielded from secret image by dividing into blocks and transforming their color characteristics to those of corresponding blocks of target image (source video). The information required for recovering the secret image is embedded into the video, into the created mosaic image by lossless data hiding using a key.
