Abstract

Steganography is a part of information hiding in covering the hidden message in any medium such as text, image, audio, video and others. This paper concerns about the implementation of steganography in text domain called text steganography. It intends to concentrate on letter-based technique as one of the representative techniques in text steganography. This paper displays some techniques of letter-based that is integrated in one system technique displayeed in a logical and physical design. The integrated system is evaluated using some parameter that is used in order to discover the performance in term of capacity after embedding process and the time consuming in the development process. This paper is anticipated to contribute in describing the implementation of the techniques in one system and to display the performance some parameter evaluation.

Highlights

Steganography is best known as the knowledge of art and science in hiding messages of data that cannot be recognized by human vision
This paper introduces the letter-based technique of text steganography as the part of category of feature-based technique
These three techniques is integrated in one interface system which are displayed in use case and sequence diagram of logical design and physical design

Summary

INTRODUCTION

Steganography is best known as the knowledge of art and science in hiding messages of data that cannot be recognized by human vision. This paper intends to focus on text steganography category by looking at featurebased technique This technique covers hidden message based on pattern letter or length of the word that conceals and seem nothing changes happen in the text. Feature-based can define as a technique that altered unique feature characteristic in text based on code word [9] It covers hidden message based on pattern or length letter of the word that conceals and seem nothing changes happen in the text [10]. One of feature-based technique is letter-based that embed the technique the text in any language that use A-Z letters This this paper compare the three techniques on letter-based which are Changing Alphabet Letter Patterns (CALP) [11] Curve in Character Subheading (CURVES) and Vertical Straight Line (VERT) [12]. The letter that does not have a vertical straight line hide 0 bit and the letter that has vertical line character hides 1 bit
