ABSTRACT:
Internet based communications are evolving at a tremendous rate. Encryption of data has become an important way to protect data resources especially on the Internet, intranet sand extranets. Encryption involves applying special mathematical algorithms and keys to transform digital data into cipher code before they are transmitted and decryption involves the application of mathematical algorithms and keys to get back the original data from cipher code. The goal of security management is to provide authentication of users, and integrity, accuracy and safety of data resources. Moreover, an image-based data requires more effort during encryption and decryption. The model for encryption and decryption of an image using auto generated key which is generated by image. The Internet has facilitated the development of a worldwide ‘Virtual Community’ free from the constraints of time and geography. Due to the Internet there is no distance between a person located in one place and experts around the globe. Through electronic mail / voice mail / video mail it is possible to solicit the opinion of experts. Moreover, Telemedicine is becoming popular in the specialties of radiology, pathology, critical care and psychiatry, where data is in the form of image. It is required to ensure confidentiality and security for transmitting certain image-based data over the Internet. The aim of security management is to provide authentication of users and integrity, accuracy and safety of data resources. The model for encryption and decryption of an image is designed with the same purposes
