Audio steganography using bit modification
نویسنده
چکیده
A method of embedding a covert audio message in a cover utterance for secure communication is presented. The covert message is represented in a compressed form with possibly encryption and/or encoding for added security. One bit in each of the samples of a given cover utterance is altered in accordance with the data bits and a key. The same key is used to retrieve the embedded bits at the receiver. The results, based on cover signals from a clean TIMIT utterance and a noisy aircraft cockpit utterance, show that the technique meets several major criteria for successful covert communication.

Steganography is the science that deals with conveying secret information by embedding into the cover object invisibly. In steganography, only the authorized party is aware of the existence of the hidden message to achieve secret communication. The image file is mostly used cover medium amongst various digital files such as image, text, audio and video. The proposed idea of this research work i...

Security of the digital information is becoming primary concern prior to transmitting the information itself via some media. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification or destruction. In this proposed method, the carrier file and the secret message are taken into audio format and a pattern matchin...

In this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (Steganography). Data is encrypted bytwo methods before embedding to increase reliability. Then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.

This paper is devoted to VLSI technology for high security purpose. Textual information is embedded in to an audio using LSB coding and it is encrypted and decrypted by Steganography algorithm. Low bit encoding or Least Significant Bit (LSB) encoding technique is proposed to encode the least significant bit of a host file with a bit of the Steganography data. This method assumes that this alter...

Digital Steganography is used to protect digital content or data such as text, images, audio and videos that have been tampered maliciously. In this paper we maintain the quality of audio and image and to ensure the ownership, we propose a new LSB (least significant bit) using edge detection in digital steganography. We apply a 2-level steganography on images and audio which make the data which...
