Formant enhancement based speech watermarking for tampering detection
Unauthorized tampering in speech signals has brought serious problems when verifying the originality and integrity of speech signals. Digital watermarking can effectively check if the original signals have been tampered by embedding digital data into them. This paper proposes a tampering detection scheme for speech signals based on formant enhancement-based watermarking. Watermarks are embedded...
متن کاملTampering Detection Scheme for Speech Signals using Formant Enhancement Based Watermarking
Unauthorized tampering in speech signals has brought serious problems when verifying their originality and integrity. Digital watermarking can effectively check if the original speech signals have been tampered by embedding digital data into them. To be effective, watermarking method should be implemented according to four requirements of (1) inaudibility to human auditory system, (2) blindness...
متن کاملImage Tampering Detection Using Compressive Sensing Based Watermarking Scheme
In this paper, we describe an image watermarking scheme using compressive sensing for detection of image tampering. We exploit dimensionality reduction and inherent computational security offered by compressive sensing. The frequency band containing the high energy is used to compute the hash and then its pseudo-random projections are obtained. These projections are embedded as a watermark into...
متن کاملDetection of Tampering in Image Using Watermarking
In the last few years there is a tremendous development in the area of high quality digital camera technology. So our life is full of the use of these digital images. However now a days there are lot of software (for example Photoshop, Photoscape, Photoplus and Picasa etc.) that can be used to modify these digital image. Therefore we cannot use these images as a proof or evidence. Therefore det...
متن کاملA Novel Watermarking Technique for Tampering Detection in Digital Images
A novel fragile watermarking technique is proposed for hiding logo information into an image by tuning block pixels based on a bitmap parity checking approach. A secure key and a random number generator are used to hide the logo information in a secret, undetectable, and unambiguous way. The characteristics of the mean gray value and the bitmap in a block are exploited for performing the embedd...
