Protection of Secret Textual Data Using Steganography Based System Khalid Buryk S Alqarni Bishah University, Faculty of computing and Information Technology, Department of Cybersecurity, Bishah City, Saudi Arabia ---------------------------------------------------------------------***---------------------------------------------------------------------

Abstract – Recently, capabilities of attackers have been

increased dramatically in terms of compromising secret data exchanged among users over the Internet. Using cryptographic approaches contribute to ensure confidentiality of data, but they do not provide secrecy of communication between the connected parties. Steganography can be used to strengthen cryptographic approaches by hiding secret data within innocent audios after passing an encryption stage. This adds second level of protection against attacks as well as hiding the communication itself between sender and receiver. This work proposed an enhanced steganography-based approach to protect secret data by embedding within audio files. Encryption using 3-DES is employed to create the first defense, while hiding in Least Significant Bit (LSB) creates the second defense with respect of ensuring high matching between cover file and stego file, high resistance against attacks, and high accuracy of retrieving the hidden data. The proposed approach achieves better performance in terms of PSNR, SSIM, and correlation.

Fig -1: General scenario of encryption-based system. Attackers can be located between the sender and receiver, where the malicious goal is obtaining cipher data through evadrosping the communication network. In this case, illegal modification can be applied easily, which in turn means losing of data integrity. Moreover, the communication between the sender and receiver is revealed. Research questions. The research questions can be listed as follows:

Key Words: Cover_object, Hidden_Data, Stego_key, Stego_object, LSB, Attacker.

1.INTRODUCTION Steganography and the logic behind it. Steganography is the technique of hiding secret data within an ordinary, nonsecret, file or message in order to avoid detection. The logic behind it is related to the fact that states "everything stored on the computer is converted into zeros and ones", and thus, it is possible to hide zeros and ones (secret data) within other zeros and ones (other files) [1].

How to hide the communication between the sender and receiver?



Proposing two-level of protection using 3-DES encryption and hiding within audio files.



Selection of hiding location based on ensuring lowest level of distortion caused by hiding process.



Providing extensive experiments to validate the proposed approach along with comparison with similar works.

Organization of paper. The paper is structured so that section 1 provides related work. Section 2 presents the proposed approach. Section 3 shows the experimental results. Finally, the paper is concluded in section 4.

Statement of problem. The problem is stated based on the general scenario of encryption, as shown in Figure-1.

How to ensure integrity of secret data?

Contribution. This paper provides the following contribution in the field of steganography:

Terms in steganography domain. Secret data, which is the data that requires protection against malicious actions, such as illegal modification and unauthorized access. CoverObject, which is the file that hosts the secret data. StegoObject, which is the file that is generated as an output of performing hiding process. Stego-Key, which is the key that is used for encrypting secret data [2].
