Abstract:
Steganography aims to hide secret messages into a cover media, such as text, audio, image and video, without drawing suspicious. In many applications, the most important requirement for steganography is the security, which means that the stegos should be visually and statistically similar to their corresponding covers. Usually, there are several factors to influence the security performances significantly, such as the hiding scheme, the length of the secret message to be embedded, and the selection of the cover medias. On the other side, steganalysis firstly tries to differentiate stego medias from covers, then further estimate the length of the secret message, and finally extract and decipher the secret message as the ultimate goal. Integrity of the election process will determine the integrity of democracy itself. So the election system must be secure and robust against a variety of fraudulent behaviors, should be transparent and comprehensible that voters and candidates can accept the results of an election.
Existing Methods:
LSB Embedding in Spatial Domain
The basic idea in LSB is the direct replacement of LSBs of noisy or unused bits of the cover image with the secret message bits.
Till now LSB is the most preferred technique used for data hiding because it is simple to implement offers high hiding capacity, and provides a very easy way to control stego-image quality
