TRANSMISSION OF ENCRYPTED IMAGE OVER A NETWORK WITH HIGH SECURITY
Mohammad Sajid Qamruddin Khizrai · 2014
The security of and information is being used from an ancient age. In an ancient age the information was also hiding using different methods called steganography. It is the process of securing information behind any one or many of the other images. Now a day’s steganography is also using for image security, but most widely used method is encryption and decryption. Image Encryption is a process of hiding image from unauthorized access with the help of secret key that key can be private or public .It is used in many areas where the security risk is very high. The encryption and decryption mechanisms will improve the security. Information security is a very important issue in this world, when the information is transfer from one geographically location to another geographically location through network there is chance of steal of information through network. Generally information is encrypted and decryption using one encryption key and one decryption key for information such as image. In our proposed work an image is encrypted in various parts using different keys, for each part of the image. Now a day’s parameters (like Bandwidth, Storage, and time etc.) are not the problem when security is matter.
