Description:METHOD FOR AUDIO STEGANOGRAPHY USING COMBINED APPROACH OF COMPRESSION & CRYPTOGRAPHY
Field of the Invention
[0001] The present invention relates to the field of audio steganography, and more particularly, to a method for securely communicating data using a combined approach of compression and cryptography within an audio carrier signal.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Steganography is the art and science of hiding information in plain sight, without arousing suspicion from unintended recipients. Unlike encryption, which focuses on securing the message, steganography aims to conceal the fact that a message is being transmitted. The use of steganography can be traced back to ancient Greece and Rome, where secret messages were hidden beneath wax tablets, tattooed onto the scalps of slaves, or even encrypted in a loaf of bread. Today, steganography is widely used in digital communications, where it provides an additional layer of security to protect sensitive information.
[0004] The advent of digital media has made steganography a practical and effective tool for concealing information. In digital steganography, information is embedded in a host file such as an image, video, or audio file, without altering the perceptible properties of the file. For example, in image steganography, the data to be hidden is embedded in the least significant bits (LSBs) of the pixel values, which do not significantly affect the image quality. Similarly, in audio steganography, the data is embedded in the audio signal, which can be imperceptible to human hearing.
[0005] Steganography has a range of applications, including covert communication, digital watermarking, and copyright protection. In the context of covert communication, steganography can be used to conceal sensitive information such as military intelligence or corporate secrets from unintended recipients. Additionally, steganography can be used in digital watermarking to embed copyright information or other metadata into digital media. This can aid in identifying ownership or tracing illegal distribution of copyrighted material.
[0006] However, the use of steganography also poses a challenge for law enforcement and national security agencies, as it can be used by criminals and terrorists to communicate and plan activities. Therefore, it is important to develop effective steganalysis techniques to detect the presence of hidden information in digital media.
[0007] All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
[0008] It also shall be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. This invention can be achieved by means of hardware including several different elements or by means of a suitably programmed computer. In the unit claims that list several means, several ones among these means can be specifically embodied in the same hardware item. The use of such words as first, second, third does not represent any order, which can be simply explained as names.

The audio output module is used to transmit or store the steganographic audio signal.
[00013] The compression module utilizes a lossless compression algorithm selected from the group consisting of Huffman coding, arithmetic coding, Lempel-Ziv-Welch (LZW) coding, Burrows-Wheeler Transform (BWT) coding, and Run Length Encoding (RLE). The cryptography module utilizes an encryption algorithm selected from the group consisting of Advanced Encryption Standard (AES), Rivest-Shamir-Adleman (RSA), Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), and Elliptic Curve Cryptography (ECC).
[00014] The steganography module employs a steganographic technique selected from the group consisting of least significant bit (LSB) substitution, echo hiding, phase coding, spread spectrum coding, and frequency masking. The system also includes a data extraction module, which is configured to reverse the steganography, decryption, and decompression processes to recover the original data from the steganographic audio signal, enabling authorized recipients to access the concealed data.

The following sections elaborate on the key technical advancements of this method.
[00058] Integration of Compression and Cryptography:
[00059] One significant advancement of the method is the integration of compression and cryptography techniques. By combining these two processes, the method achieves efficient data size reduction while maintaining data integrity and security. This enables the concealed data to have a minimal impact on the audio quality of the carrier signal, which in turn makes the steganographic process more difficult to detect. The integration of compression and cryptography also allows for efficient use of bandwidth and storage resources while maintaining a high level of security.
[00060] Enhanced Covert Communication:
[00061] The method provides an enhanced level of covert communication by utilizing audio steganography. Audio steganography techniques, such as least significant bit (LSB) substitution, echo hiding, phase coding, spread spectrum coding, and frequency masking, allow the method to embed encrypted data within an audio carrier signal in a way that is difficult to detect and remove. This makes the method particularly effective for secure communication in scenarios where discretion is paramount, such as in military operations, intellectual property protection, or sensitive diplomatic communications.
[00062] Adaptable to Various Data Types and Audio Carrier Signals:
[00063] Another technical advancement of the method is its adaptability to various types of data and audio carrier signals. The method can accommodate different types of data, such as text, images, or other digital files, and can be applied to a wide range of audio carrier signals, such as music files, speech recordings, or ambient sounds. This flexibility allows the method to be used in diverse scenarios and applications, making it a versatile solution for secure data communication.
[00064] Robustness Against Detection and Removal:
[00065] The method is designed to provide robustness against detection and removal of the concealed data. By integrating compression, cryptography, and steganography techniques, the method minimizes the impact of the concealed data on the audio quality of the carrier signal, making it more challenging for potential eavesdroppers to detect or extract the hidden data. This robustness ensures that the data remains secure even if the audio carrier signal is intercepted or analyzed by unauthorized parties.

Method for Audio Steganography Using Combined Approach of Compression & Cryptography
Abstract
The present invention is a method for audio steganography using a combined approach of compression and cryptography. The method aims to provide a secure and efficient way to transmit confidential data using audio signals. The method involves compressing the data to be concealed using a lossless compression algorithm, encrypting the compressed data using a symmetric or asymmetric encryption algorithm, and embedding the encrypted data within the audio carrier signal using a least significant bit (LSB) or other steganographic technique, generating a steganographic audio signal that conceals the encrypted data. The steganographic audio signal can then be transmitted or stored for later use. , C , Claims:Claims
