摘要：It is well-known that images are different from texts in many aspects, such as highly correlated, redundancy and the characteristics in 2D pixel matrix. Cryptography algorithm for image is not so easy. RES, AES, DES are not suitable for color images, which are 2D arrays of data. As a result, the methods of conventional encryption cannot be applied to images. The network is currently used for carrying personal information as well as financial data. Thus, it is necessary to secure the network, in order that unauthorized person cannot access personal information. Cryptography is used for p rotecting data during network communication. Encrypting information in transfer helps to secure it from hackers, because it is difficult to physically secure all access to network cannel. Standards cryptographic hardware and software are used to perform encryption and decryption. There are many cryptographic algorithms which are being used to secure data including images but all of them have some advantages and disadvantages. So there is need to develop a strong cryptography algorithm for securing the image while transferring. Graphical data is complicated in comparison with other data like text, so technique of securing them also will be difficult.
