Abstract
With the advancement of technology, the security of digital image is an important issue which is receiving considerable attention in the recent past. In the past few years, several encryption algorithms have been proposed as means to protect digital images against cryptographic attacks. The encryption process transforms the 2-D pixel array into a statistically uncorrelated data set. In this project, a number theory and image based encryption scheme is proposed for the security of data. This technique calculates the sum of matrix of image and the number of elements in an array. By using these two things we generate a random number which is used for decryption.
