Abstract :
Easy and fast access to data and their exchange in various fields through social networks accessible to the public is increasing daily during the new era. Data hiding technique plays a critical role in telecommunication by providing security in data exchange and privacy protection of individuals or organizations utilizing social network channels. Reversible data hiding (RDH) technique based on image interpolation is among the methods welcomed by researchers in the field of data hiding in digital images in recent years. Here, high embedding capacity (EC) was obtained, as well as maintaining the visual quality of the stego image (SI) by applying some of the most critical interpolation techniques based on the proposed method employing n-bit division of the binary stream of secret data (SD) and their conversion into positive and negative decimal ones. Based on the results, high EC and more appropriate peak signal-to-noise ratio (PSNR) compared to the competitor method were achieved uniformly using some interpolation techniques on all of the standard tested images. On average, the EC and PSNR obtained on all tested images increased by 22.36 and 15.9% compared to the competitor method, respectively.
