An Efficient Data Steganography Using Adaptive Pixel Pair Matching With High Security

Abstract

Steganography is often outlined as the study of invisible communication that typically deals with the ways in which of hiding the existence of the communicated message.Steganography is nowadays extra vital due to demand of secure communication during this era of vulnerable computer users. The main concept of APPM is to use the pixel pair as a reference coordinate and find a coordinate inside the newly and specially projected compact area set of this pixel pair according to a given message digit.Then that pixel pair gets substituted by the searched coordinate to obscure the digit. It additionally provide adjustable payload and permits users to select digits in any notational arrangement for data embedding, and therefore achieves a larger picture quality. A good data-hiding method ought to be capable of evading discernible and statistical detection as bestowing an adjustable payload. APPM with high security has come to be straightforward, economical embedding method for the data obscuring by removing the assorted shortcomings discovered in the various previous methods established on PPM, such as low-payload problem in EMD. It additionally proposes very less MSE and good PSNR than the OPAP, DE and APPM. High security is provided in this paper by providing an external password along with the secured key. As well as this method is secure below the detection of some well- known steganalysis techniques.
