Information security is the key in the era of electronic data exchange.Images constitute a large portion of the electronic data.Confidentiality of color images is a difficult process.Most of the image encryption algorithms are complex and compromise on the quality of the image.This paper proposes a new image encryption based on random pixel permutation with the motivation to maintain the quality of the image.The values used in the encryption process are preserved in the form of a 64 bit key and sent to the receivers.The receivers jointly use the key and the shares to see the secret.
