With the fast progression of data exchange in an electronic way, information security is becoming more important in data storage and transmission. Because of widely usage of images in industrial process, it is important to protect the confidential image data from unauthorized access. Security of these images while transferring over the internet happens to be more critical, when they are confidential weapon photographs, clandestine military data, furtive architectural designs of financial buildings and top-secret war plan designs, etc. In this paper, the authors have proposed a new partial symmetric-key based block cipher to meet the special requirements of secure image transfer.
