摘要：Security of the confidential information has almost become a challenge now-a-days because of large amount data being exchanged on the internet. For the protection of these data from unauthorized access various methods have been developed and are in practice today.

For hiding secret data in digital images, large varieties of steganographic techniques are available, some are more complex than others, and all of them have their respective pros and cons. This paper tries to give thorough understanding of some recently developed image steganography algorithms. The study shows that steganography has played a very beneficial role in various applications. It would be very useful and will provide a better platform for the beginners who want to work in steganography.
