Implementation of Invisible Digital Watermarking on Image Nonlinearly of Arithmetically Compressed Data
Sabyasachi Samanta, Saurabh Dutta · 2010
paper presents how long textual information are encrypted and compressed to a number of floating point numbers and it to binary equivalent; then to substitute that stream of bits some suitable nonlinear pixel and bit positions about the image depending upon the key; also to retrieve that hidden data bits from that pixels and to decompress into its original information.
