A Novel Approach of Amazigh Text Steganography based Elliptic Curve

Abstract

Techniques for information hiding are becoming increasingly more sophisticated and widespread. Steganography is the art and science of hiding information by embedding data into media. Over the years we have come across several steganographic techniques designed for hiding information inside digital media like image, audio and video files etc. Text steganographic is more difficult than others because there is a little redundant information in text file. In this paper, we attempt to provide a new steganographic method for hiding information inside Amazigh Unicode text documents. This approach combines schemes of cryptography with steganography for hiding secret messages. Therefore, the proposed method has a high hiding capacity because it inserts one character at each time instead of hiding one bit in the existing methods. Moreover, our algorithm can be applied in different size textual data.
