Study on generating a Cryptography Algorithm for image transmission with no losses

In this research work an effective algorithm is proposed for Digital Image Transmission to happen without any losses. Proposed work provides a new symmetric key generation method for colour images. The encrypted image is obtained with the help of three OTP (One Time Password) which provide two public key of matrix size 4*4 and 8*8 along the image. To obtain original image from encrypted data, a decryption process (reverse process of encryption) was used. Through this, the original image was retrieved successfully at receiving end. To make transmission lossless, a perfect divisible matrix approach has been followed; encrypted image was transmitted by changing the pixel value of original image The experimental result has been shown by implementing proposed algorithm in MATLAB simulator software. Mean square error represents that proposed algorithm is lossless for image transmission.
