Reversible Image Authentication Based on Watermarking

Abstract

In this paper, we propose a new reversible image authentication technique based on watermarking where if the image is authentic, the distortion due to embedding can be completely removed from the watermarked image after the hidden data has been extracted. This technique utilizes histogram characteristics of the difference image and modifies pixel values slightly to embed more data than other lossless data hiding algorithm. We show that the lower bound of the PSNR (peaksignal-to-noise-ratio) values of watermarked images are 51.14 dB. Moreover, the proposed scheme is quite simple and the execution time is rather short. Experimental results demonstrate that the proposed scheme can detect any modifications of the watermarked image.

Athena: capacity enhancement of reversible data hiding with consideration of the adaptive embedding level

“…Lee et al [11] proposed a reversible image authentication technique which is based on histogram modification similar to Ni et al [5], and claims to provide lower distortion. In their work, they used the differencehistogram techniques which are not regular in shape and provide a much higher peak point.…”

“…According to [7,8], RDH techniques could be classified into the following categories: lossless compression-based scheme [9,10], histogram approach [5,6,11], difference expansion [12], prediction error expansion [13,14] and two-dimensional histogram approach [15]. The basic concept of lossless compression-based scheme is to compress a feature set of cover image to save the space for embedding data [9,10].…”

Practical Perceptually Adaptive Approach to Video Logo Placement in TV Broadcasts

“…For example, a corporate logo could be used to indicate ownership. Digital video and image watermarking can typically be divided into two categories: (i) Invisible watermarking [1]- [6], and (ii) Visible watermarking [7]- [12]. An overview of video watermarking techniques can be found in [13].…”

Contemporary Approaches to the Histogram Modification Based Data Hiding Techniques

“…It is fundamentally based on block−based. Lee et al (2006) also proposed a reversible data hiding scheme based on histogram modification of difference images. To increase data hiding ability, Chang et al (2008) presented an efficient extension of the histogram modification technique by considering the pixel difference instead of simple pixel value and Teng et al (2010) had some other similar proposals.…”
