The components of multimedia such as text, image, and audio and video are integrated and transmitted over a network. The protection of information from the unauthorized access is of high concern in the digital era. The advanced cryptographic techniques are employed in order to secure the multimedia information to preserve the data confidentiality and to share the information only with the intended users. The paper proposes encryption and decryption of an image based on the points on the elliptic curve. The pixels of the image are taken in the binary form and linked to a point say, (Xi, Yi) on the elliptic curve. An image is encrypted using the elliptic curve points and successfully decrypted by utilizing the same elliptic curve in Python 2.7 version operating on the Ubuntu operating system.
