Cryptography is the science of converting confidential information into unintelligible format. To provide security and authentication to the data, many algorithms and techniques were evolved, in which the cryptographic techniques remains best. For the encryption process, Images were considered as the best source to maintain security. The usage of image is good solution for providing better communication. In this proposed method, a new image encryption method is placed. According to proposed methodology, the given image is encrypted as stream ciphers based on the threshold value computed. Two stages were being defined for proposed methodology, first one is the threshold computation, and second one is encryption. This method remains securable and quick access of data is taken place.
