An Overview of Digital Image Steganography
2013
International Journal of Computer Science & Engineering Survey
Preserved Fulltext
Hiding Capacity plays a vital role for efficient covert communication. This is achieved by Steganography. ...
In this paper, a highcapacity Image Steganography schemes are discussed for different file formats. Covert communication is taking place by encrypting the password for information to be protected. ...
The aim of the covert communication is to hide the fact that the communication is being occurred. Covert communication ensures privacy. ...
