Abstract: The key objective of image steganography is to hide the secret data in different embedding medium called as carriers. These carriers can be images, video files, audio files and text files. This paper discussed recent steganographic techniques for image files. Imperceptibility, embedding capacity and robustness are the key issues of image steganography. These recent techniques are analysed the key issues of steganography and discussed the merits and demerits of these techniques, to identify the suitability for data hiding method which will provide guidance to the people working in this field. Steganalysis was also discussed separately.

Keywords: digital images; image steganography; spatial domain; frequency domain; steganalysis; data hiding.
