Information security is a very important topic in fast growing communication technologies. Image security is also a part of this information security. In this paper we propose a novel technique for image encryption based on carrier image. Here, pixels of a carrier image are created by amplitude values of multiple sine waves generated by alphanumeric password. Finally this carrier image is added with original image to obtain encrypted image. Decryption process involves the same procedure to create carrier image and it is added with the encrypted image to get original (decrypted) image. Experiment is conducted for various combinations of multiple waves to generate various patterns in carrier image
