The process of hiding an information in a carrier is referred to as data hiding and there are several methods for this process even though there are certain advantages and drawbacks of most of these methods.one or more data hiding methods can be deployed at the same time depending on the type and level of the intended application. Data information can be hidden in several forms of carriers such as audios, texts, video, protocol, image, and DAN. Some of the digital image data hiding methods pay more attention to image security while some focus on the robustness of the image hiding process and on the imperceptibility of the hidden image. One of the major concern in certain applications is the capacity of information to be hidden in the carrier; as such, the major aim of some previous studies has been to achieve two or more of hidden images’ security, imperceptibility, robustness, and capacity. However, some of these image parameters are sometimes complimentary as only one can be realized at the expense of the other. In this paper, some of the existing digital image hiding techniques were reviewed while a comparative study was conducted between 3 of these hiding techniques.
