In this paper an efficient (2, 2) secret sharing scheme has been proposed where the generated shares are meaningful and the aspect ratio and image dimension of the shares remain constant with respect to the source image. In the CARVCMS, instead of generating new pixels for shares, the shares are generated by random inversion of the levels of the pixel values. The scheme is more secured and very easy...
In this paper a secret message/image transmission technique has been proposed through (2, 2) visual cryptographic shares which are covered by meaningful images so that a potential eavesdropper won't know there's a message to be read. A binary image is taken as cover image and authenticating message/image has been fabricated into it through a hash function where two bits in each pixel within four bits...
The importance of identifying a song from similar songs is increasing with the growing importance of high quality editing and processing of audio signals. In this paper a novel technique to protect piracy of quality songs has been derived using amplitude manipulation. A technique to identify a particular song by enforcing authentication via amplitude manipulation has been developed based on sampled...
