Image Encryption Technique Using Lagrange Interpolation

A new proposed technique used to encrypt the private image for secure transfer information. The proposed technique was designed using the Lagrange interpolation polynomial calculation in key generation and in encryption. A three stage for encryption and coding was proposed to complete the encryption of private image. RC6, Quadtree and Xor techniques were used in building the proposed technique. A short time in operation with a good visual encryption view encryption was got from implementing the proposed technique.
