Steganography is to conceal information in a carrier file or cover file. This is done to make secure communications without attracting attention of any other person except the sender and the receiver. This paper deals with digital steganography. The carrier file used in this study is JPEG images. The hidden data is in various formats like audio, video, plain text, and pdf formats. The cover image with hidden data in it is called the steganography file. The files were steganographed using various applications like Quick Stego, Invisible secrets, Our secret and Steg. When data is incorporated to the original file there will be changes done to the integrity of the file that is not visible on viewing the file. This data added is hidden in the file. Therefore there is possibility that the metadata of the file changes and hence metadata analysis can be done to detect steganography..
