A Security System for a Digital Camera: Using Cryptographic Secrecy in Steganographic Embedding - Tapa blanda

Sinopsis

This book is mainly focus on hiding of text, image and audio in to an image. This steganography technique is important Technique, because even though the stegno image is filtered using LSB filter it cannot be detected i.e., to make it much difficult to automate. According to the steps of design, there are 16 main cases with their 6 sub cases that cover the aspects of the input data. The pixels are selected according to the segmentation of the cover image. Steganography algorithm provides high security by using the two theories but the new algorithm is designed with three layers which works individually and provide unbreakable security wall through the encryption of the input data and confuse steganalys is too. Two passwords are given one password is for encryption of data and the second password is for pixels selection. Here the password is not important but the length of the password is important. Depending on the password length the pixels are decided. The algorithm for cryptographic secrecy in steganographic embedding for hiding digital data (image or text or audio) into image is been designed and implemented using MATLAB.
