ENCRYPTION AND DECRYPTION OF DIGITAL IMAGE

Abstract

This paper aims at improving the level of security and secrecy provided by the digital image encryption. The image encryption and decryption algorithm is designed and implemented to provide confidentiality and security in transmission of the image based data as well as in storage. This new proposed encryption algorithm can ensure the lossless of transmissions of images. The proposed encryption algorithm in this study has been tested on some images and showed good results.  
In present times, the protection of multimedia data is becoming very important. The protection of this multimedia data can be done with encryption. There are so many different techniques should be used to protect confidential image data from unauthorized access.  
Image encryption is one of the most important applications in transferring images through the Internet and cellular phones.. The algorithm encryption and decryption of an image transform an image into cipher code using the random keys, which allow users to have confidentiality and security in transmission of the image based data as well as in storage in the data warehouse.
