Confidentiality is major task for every sector, keeping things confidential among the organization is the most important factors. Providing security for information is also major concern for the fast growth of the digital exchange of data storage and transmission. As there is rapid growth of using images in many fields, so it is important to protect the private image data from intruders. In this paper, we propose Email authentication for encrypted and decrypted image. In our framework, first, the confidential image will be encrypted using a symmetric key algorithm, Advanced Encryption Standard (abbreviated as AES) by the sender and the encrypted image will be send via Email to receiver. The Cryptographic algorithms provides security to the image, as we proposed AES to our framework it will become more difficult to crack the original image for intruders. Moreover there are some other encryption algorithms to encrypt and decrypt the image but Advanced Encryption standard has its unique features like it protects from brute-force attack and image takes less rounds to encrypt,etc. that gives more security compare with other symmetric algorithms. And Email provides a secure transmission of encrypted image. The above results and analysis for crypto system based on AES algorithm give a high performance. So we have reason to believe that use of this method to encrypt and decrypt the image and sending via Email will have a very good prospect in the future.
