A Study of Image Hiding Techniques in The Spatial Domain

Abstract

Currently, information hiding has become an effective technique and has increased interest due to the rapid growth of Internet use. Many techniques can hide and transmit private information. The science of hiding information within the carrier's body ensures secure communication over the Internet so that it can only be recognized and detected by the sender and recipient. Thus, we can use many forms of a carrier, such as images, video, protocol, and audio. However, digital images are most commonly used because of their frequency on the Internet. There are many techniques for hiding information, each with advantages and disadvantages. In this study, we reviewed the techniques used to investigate the term "hiding" by reviewing and collecting various studies related to this field published between 2015 and 2021. This study assessed several ways of addressing this problem. Four measures -image quality, message capacity, and securitywere used to assess the additional computational complexity of each method. Finally, the results presented and summarized as performance, security, and hidden image quality are essential for evaluating the approach.
