Application and Analysis of Unified Data Embedding and Scrambling Method

Reversible data hiding is a type of data hiding techniques whereby the host image can be recovered exactly. Being lossless makes this technique suitable for medical and military applications. Recently, as a new trend, some researchers exploited reversible data embedding techniques to deliberately degrade image quality to a desirable level of distortion. In this paper, a unified data embedding-scrambling technique called UES is proposed. This technique received more attention because of its high payload and adaptive scalable quality degradation. The aim of this paper is to present a review of USE data hiding techniques proposed so far in order apply and analyze this technique on the 7 images (each of dimension 512×512 pixels) from the USC-SIPI standard test image dataset. Validation of proposed USE technique is considered by two parameters such as image quality i.e is measured in terms of SSIM value and by visual inspection. Along with that, USE technique is functionally compared with other various exiting data hiding techniques.
