Abstract
In this paper, we have developed a software tool "Photopark" to enhance images and to provide security. The software developed provides filtering tools, volume adjustment, image resizing, converting and all other features provided by an image editing tool. Apart from the features provided by an image editing tool, PHOTOPARK provides image security for both text and images. When the image transmission is considered scrambling of images is done which provides the security. In the proposed paper the images are transmitted efficiently by the Feistal Cipher Algorithm where the image is broken in to equal parts and the text transmission is implemented through the text transmission algorithm. The software provides excellent security and has many desired cryptographic qualities. The encrypted information is hidden within the pixels of an unassuming cover image by slightly modifying the gray levels of the carrier image. The resulting innocent-looking picture can then be transmitted electronically without arousing suspicion, and will have the security of both the hidden message plus the encryption of the message.
