Enhancement of Security of Digital Data with Steganography Technique

Abstract

In this era of Internet and Technology there is a need to secure digital data from unauthorized users. This can be done with the use steganography techniques. The selling of softwares in the form of digital images and video sequences is very much enhanced due to the cost effectiveness and improvement in technology. But this digital are also at risk to accidental attacks. Nowadays the most important concern is the protection of digital data and therefore it is gaining interest among researchers. The storing and transferring of digital data, needs many security concerns that are sensitive and if this data is lost, counterfeited, or hacked, it may be impossible to recover. The security of this transmitted data can be increased by the application of steganography techniques. In this the digital data can be hidden in the host image and this image is transferred to the receiving end instead of the actual software data. Then by using a secret key, the hidden data are extracted accurately from the carrier image. The data is hidden in such a way to minimize the degradation of actual data. In this paper a method is described to handle attacks on the carrier image.
