The model for encryption & decryption of an image is designed with the same purposes no needed to send public or private key, first input image then generate auto generated key for image encryption using stream cipher , encrypted image will be divide into four parts then algorithms provided auto sequence number to image, transmit four segmented image, In other end first takes segmented image then all segments merge together then generate auto generated key and using this key decrypt image and analysis quality of image.
