“…Later, due to its anonymity and covert nature people adopted it in their personal communication i.e. to communicate privately and secretly with a person over Internet with security such that no intruder can inspect the invisible communication [17]. Sharing of top secret or high level documents between international governments is one of the legitimate use.…”

“…An attempt is made to overcome this issue through the random selection at the cover image for embedding. This mechanism is referred as Random or scattered LSB [17] and it offers more payload capacity [29]. Neil F. Johnson [20] proposed a method that sharp areas can hide large amount of data if it is applied at edge image and it cannot hide more data when it works at smooth images.…”

“…However they are also good for image steganography. It has two phases namely encoding phase and decoding phase [17]. In encoding phase, the sender marks changes in the cover image in order to get a stego image and in decoding phase, the receiver reconstruct cover image from stego image in order to get message and cover image.…”

“…Figure 2 illustrate this method. During World War I, the Germans communicated se-cretly using a sequence of characters and words referred as null cipher [11] In World War II microdot technique, which is very difficult to judge, used by German people and Invisible ink were used for hiding the data in invisible manner [17]. Linguistic Steganography were also used as a poem or stanza in which certain letters, generally the first in each line, build a motto, message or name when recite in sequence [26].…”

Word 'Steganography' is originated from Greekand has been used in several forms for 2500 years which is a art of hiding confidential data in any digital manner in such a way that no one can concealed it. It has found practise in various section like in military, government, diplomatic, medical, personal Interest) is highlighted. In addition, different types of Image file used in image steganography and performance parameter are discuss well. and intelligence agencies. This survey paper put the light on the basic of image steganography along with its different techniques and sub-techniques. Cover selection with recent trend ROI (region Of

“…The IWT uses a complete technique of DWT but maps integers to integers in the output. In discrete wavelet transform, the wavelet filter has the floating point coefficients [21]. When the secret information is stored, then data loss occurs because of the truncation of integer value due to floating point coefficient.…”

Steganography is the technique with which the confidential data is hidden under the cover medium such as image, without reflecting any clue on the cover image. Many algorithms are designed to provide the security for the communication of data over the Internet. The good steganographic algorithm is identified by the performance of the algorithm measured with the help of the parameters such as PSNR, MSE, robustness and capacity to hide the information in the cover image. This paper analyzed the Digital Image Steganographic algorithms in spatial and frequency domain.
