A Novel Approach of Bulk Data Hiding using Text Steganography

Abstract

Steganography enables individual to attain privacy by providing efficient techniques to hide data. The term steganography derives its existence from ‘Johannes Trithemus’ literary work titled “Steganographia”. It can be applied to several digital medium such as text, image, audio and video. Research work is going on to improve the performance metrics so that a large amount of data can be hidden by consuming less time and memory overhead. Text steganography can be achieved by using text file as a cover. Text file consume less storage space and can be accessed with low bandwidth. Zero Distortion Technique [14] is applied on text along with abbreviation method for achieving optimal results. For encryption Indexed Based Chaotic Sequence approach has been used [11]. The results obtained by the trio effect are evaluated on the basis of performance metrics like hiding capacity, time consumption and results compared with other text steganography techniques.
