Cryptography in the Web: The Case of Cryptographic Design.
A digital watermark and signature method for image authentication using cryptography analysis is proposed. The digital signature created for the original image and apply watermark. Images are resized before transmission in the network. After digital signature and water marking an image, apply the encryption and decryption process to an image for the authentication. The encryption is used to.
This course is a research seminar on selected topics in cryptography, both applied and theoretical. A tentative list of topics includes: Applied cryptography: public and private key encryption, digital signatures and authentication; applications Cryptographic security: random number generation; implementation and protocol issues; side-channel attacks Factoring and discrete log algorithms.
It is for this reason that most organizations prefer to use image hiding to protect the crucial information that they move in the network. Image encryption is the cryptographic process that involves the transformation of plaintext information, using the cipher algorithm so that it is made unreadable to anyone apart from the people who have the professional special knowledge about the.

In this paper the image which is considered to be in the form of a grid, is first transformed on an elliptic curve. These points or coordinates are then encrypted and send to the recipient. At the receiver end decryption algorithm is used to convert the encrypted image into the original image. Brute force attack is infeasible for ECC because of the discrete logarithmic nature of elliptic.
