Harpreet Singh

Abstract: In order to secure delicate data, frequent and intensive internet transmission of data needs security methods. Steganography is one of many safety methods consisting of concealing data within a suitable multimedia (e. g. picture, video, audio. Steganography technologies such as capability (information size integrated) and imperceptibility (detectability level) face many difficulties. These two elements are inversely proportional to each other, resulting in a dilemma of data hiding. This article provides a review of the steganography techniques used in latest years and a critical assessment based primarily on measuring ability and, secondly, measuring imperceptibility and steganography.
