【 摘 要 】

The proposed work has focused on the security of image in order to save it from external attacks. However there have been several existing steganography mechanisms to secure the graphical contents but there are still threats from external attacks. Moreover in case of bulky image it becomes difficult to shift content over network without any loss. Thus proposed work has been introduced to allow graphical splitter mechanism to break graphical content in multiple parts by splitting image matrix in two or multiple parts according to image size. If the image size is less bulky, it could be split into just two parts or if the image size is more bulky, it could be split into more than two or multiple parts. This would save the image from being hacked or read in unauthentic manner. The proposed work would apply a key to divide image matrix in two or more than two parts so that it could not be easily understood. The proposed work is also concentrated on Threats to security, Nature of attacks, and Delay in pre-processing. It also focused on Delay during the process of encryption and decryption, Image Quality. Moreover there are several compression techniques to compress the graphical contents to increase the transmission speed. The proposed work has compared traditional compression mechanism with present splitting mechanism that would reduce the size of image along with providing security.
