Color Image Steganography Using Elliptic Curve Cryptographic Technique

S. Prabagar and S. Vasuki    

Abstract: In this research the widespread usage of ASCII art has been considered. Color image is converted into an ASCII Art by using NMF Algorithm. This art is stored as an art image. Inside this art, additional information (such as data file and mobile no or email id for sending key) is to be hidden. Both art image and hidden information are stored as stego image using 4 bit LSB Algorithm. This STEGO image is secured using Elliptic Curve Algorithm. In order to restore the original art image from stego image, the decryption key is required. This decrypting key is sent to the email id or mobile number specified during the creation of stego image. Users can decrypt the STEGO image only using the decryption key received in the mail or mobile specified. Convert the image into ASCII art, drawing the ASCII art photos is like drawing a picture in the paint application of Windows. All these processes are very easy, no experience is needed and also it is less overloaded.
