Spectral Magnitude Adjusted Data Hiding in MCLT Domain of Audio Signal for Robust Acoustic Data Transmission
نویسندگان
چکیده
Data hiding in audio signal enables acoustic data transmission by playing back the data-embedded audio and by recording the signal and extracting the data at receiver like mobile devices. In our previous work, we proposed an audio data hiding system for acoustic data transmission, of which the audio quality and transmission performance are suitable, based on phase modification of the modulated complex lapped transform (MCLT) coefficients. In this paper, we propose the spectral magnitude adjustment (SMA) technique for this data hiding system which enhances both the quality of the dataembedded audio signal and the transmission performance.

Spectral Magnitude Adjustment for MCLT-Based Acoustic Data Transmission
Acoustic data transmission is a technique which embeds data in a sound wave imperceptibly and detects it at a receiver. The data are embedded in an original audio signal and transmitted through the air by playing back the data-embedded audio using a loudspeaker. At the receiver, the data are extracted from the received audio signal captured by a microphone. In our previous work, we proposed an ...

Data hiding systems have emerged as a solution against the piracy problem, particularly those based on quantization have been widely used for its simplicity and high performance. Several data hiding applications, such as broadcasting monitoring and live performance watermarking, require a real-time multichannel behavior.While Digital Signal Processors (DSP) have been used for implementing these...
متن کاملData hiding in audio signal using Rational Dither Modulation
A data hiding system in audio signals based on a Rational Dither Modulation is proposed, which hides information in the Modulated Complex Lapped Transform (MCLT) domain. The proposed system is able to hide around of 689 bits per second, while keeping a CD-quality audio signal. Objective and subjective evaluations show robustness to classical attacks and transparency to the Human Auditory System...

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
متن کاملA New Hybrid Method for Colored Image Steganography Based On DWT
Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...
