Now a day’s information security is most wanted achievement, and its need in the communication. The intends of this entitle work is wished-for an image encryption and decryption. Image encryption is an effective approach for providing security and privacy protection for medical images. This feature is especially very useful for multi medical images where the images can be making as one. In this work applies rational operators in between two images at multi levels to make multi key image to improve security levels. This work mainly approaches two operations that are OR and XOR logical operations.
