Abstract
In now a day, Image Steganography is one of the most popular and highly secured wireless communication technique. Digital authentication in image steganography is a special extension in twenty-first century. The approach “steganography” can be categorized into two major wings—spatial domain and frequency domain. Among them, the spatial domain is very common and easy to implement. In this paper, an image steganography scheme is developed in spatial domain with proper digital authentication. The basic idea of integer theory is used to develop this particular data hiding model. More specifically, the concept of triangular number and perfect number is used to develop the system with maintaining all the necessary requirements of information security, i.e., confidentiality, integrity, and availability of data among authorized users. The speciality of this approach is keyless transposition and freeness from different powerful attacks like PRNG (Pseudo Random Number Generator), visual attack, chi-square, and histogram. The efficacy of the proposed method is analyzed with different parameters of data hiding and digital authentication.
