Comparison of various Edge Detection Techniques for maximum data hiding using LSB Algorithm

Abstract- Steganography is the art of hiding information. It is derived from the Greek word ‘’Steganos’ ’ which means covered writing, a science of secret communication. It is a tool for hiding information in a medium so that the information does not appear to exist. For hiding secret information in images there exists a large variety of steganographic techniques, some are more complex than others and all of them have respective strong and weak points. The edges of an image can be used very efficiently for hiding data. In this paper we performed a thorough investigation in comparing the different edge detection techniques and hence evaluate which technique is better for image steganograph
