A COMPARISON OF SECRET IMAGE HIDE METHODS OF STEGANOGRAPHY AND VISUAL CRYPTOGRAPHY

Abstract

During the clandestine data transmission, to protect a secret data from the hackers or intruders is one of the difficult task. In this era, when technology grows, simultaneously the challenges of the technologies also increasing rapidly. In connection with that, while selecting any technology for the particular process, we are in position to check strengthen of the technology towards to the attackers or hackers. In this paper, we have been presenting a comparison statements of different secret image hide methods. To prepare this comparison, we have chosen two popular image hide methods of steganography and visual cryptography. The steganography is a secret image encode method, which will encode a secret image into non-secret cover image. On other hand, visual cryptography is an image hide method. In this method, the original secret image is split into different shares. A single share will not be described the original information. However, the original information can be retained when combining all shares together. In this proposed work, both methods are differentiated based on the different parameters of reconstruction quality, execution time, method strength and complexity.
