A Review on Image Stegnography with Its Technique

In the last few years communication technology has been improved, which increase the need of secure data communication. For this, several scientists have applied much of their time and also efforts in an attempt to the purpose of finding appropriate ways for information hiding. Hiding Capacity plays a vital role in efficient covert communication. This is achieved by Steganography. Steganography is the science of hiding information that involves all the techniques used to exchange the secret message with low distortion of the cover medium. It can be described as the unseen communication study of that generally deals with the ways of the hiding existence of the communicated information. The hidden message may be text, image, audio, video, etc. Steganography which overcome each other’s weaknesses and create challenging for the intruders to attack or steal important data is being suggested. This paper also defines the basic ideas of the steganography. In this paper, we survey on different steganography methods for data encrypting. Steganography is a method that permits the one to hide the information within an image while adding few noticeable modifications. and also The LSB (least significant bit) based method is a popular kind of steganographic algorithms in the spatial domain. The advantage of the LSB is its simplicity to embed the bits of the message directly into the LSB plane of cover-image and many applications use this method. In this paper we try to give an overview of different LSB methods and there advancements.
