Steganography: simple implementation in c# the least significant bit (lsb) is the bit that when flipped from 0 to 1 or from 1 to 0, then no significant change will . The least significant bit (lsb) algorithm and the most significant bit (msb) textual information from the image, the image created by the application must be .
Abstract—steganography is the process of hiding one file inside another such that one of the most common methods of implementation is least significant bit. Linked pixel steganography (lps) technique is a variant of the well-known lsb 1 bare bones implementation of least significant bit steganography. Sort of lsb hiding, namely the lsb+ algorithm to prevent the sample pair analysis attack, the lsb+ algorithm is implemented on the selected subsets of pixels.
