  The aim of this study is to review the strength and weakness for the possible multimedia cover for the steganography approaches. In addition, the security level of each approach and how is probable to combine the steganography and cryptography. Steganography is an art on which the data can be hide in other data as cover, the multimedia files is the commonly used for hiding data. The main aspects of the steganography is the capacity and security, where the capacity refer to how much data can be hidden in the cover carrier, while the security concern with the ability of disclose or altering the data by unauthorized party. The multimedia files, such as, image, video, audio and text are the possible covers for hiding secure information or data. Each of these covers has advantages and disadvantages; as a result of this study we will discuss the possibility to use these files as a cover. In the last part of this study, we suggest a further direction to improve the capacity and security aspects.

  In the last few years, we have seen many new and powerful steganography techniques reported in the literature. Steganography is the art of communicating a message by embedding it into multimedia data. It is desired to maximize the amount of hidden information (embedding rate) while preserving security against detection by unauthorized parties. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. In this study intends to offer a state of the art overview of the hiding information technique using image file as a cover carrier to illustrate the possibility of using the image for hiding secure information for business and personal use.
