Title : COLOUR IMAGE STEGANOGRAPHY BASED ON CHANNEL TRANSFORMATION APPROACH TO ENHANCE VISUAL QUALITY
Jyoti Neginal1, Dr.Ruksar Fatima2

Abstract :

The interest in information security strategies is expanding due the quick expansion in the use of media content and transmission over the web employments. Accordingly, there is a need of special embedding procedure for steganography. The creator presents an original reversible data hiding (RDH) algorithm for colour pictures that further develops the inserting execution by applying a channel transformation function and a versatile expectation blunder extension Prediction Error Expansion structure. The proposed calculation will bring the first colour picture with no information misfortune from the inserted picture (which is unique in addition to target picture). This calculation uses the zero or the base place of the histogram and marginally changes the pixel esteems for inserting the information. It can insert more information when contrasted with the majority of the current data hiding calculations. A hypothetical confirmation and various examinations show that the Embedding Capacity of the proposed model is consistently more noteworthy than the other reversible data hiding techniques. The calculation has been applied to a wide scope of various colour pictures effectively. Some exploratory outcomes are introduced to show the legitimacy of the calculation.
