Steganography is not only the art of hiding information but also hiding the element of transmission of secret information. Steganography hides the secret information in another file in such a method that only the recipient understand the existence of message.
There are some requirement of steganography which are as follows :
Invisibility − The invisibility of a steganographic algorithm is the first and order condition, because the strength of steganography lies in its ability to be unseen by the human eye. The point is that one can view that an image has been tampered with, the algorithm is negotiated.
Payload capacity − Unlike watermarking, which required to embed only a small amount of copyright information, steganography objective at secret connection and thus needed adequate installing capacity.
Robustness against statistical attacks − Statistical steganalysis is the procedure of identifying secret data by utilizing statistical tests on image information. There are some steganographic algorithms leave a ‘signature’ when embedding data that can be simply identified through statistical analysis.
It can be able to pass by a warden without being identified, a steganographic algorithm should not leave such a mark in the image as be statistically important.
Robustness against image manipulation − In the connection of a stego image through trusted systems, the image can view transform by an active warden in an attempt to eliminate hidden information.
In Image manipulation, it includes cropping or rotating can be implemented on the image before it reaches its destination. It is based on the manner in which the message is embedded, these manipulations can demolish the hidden message.
It is desirable for steganographic algorithms to be powerful against either malicious or random changes to the image.
Independent of file format − With some different image file formats used on the Internet, it can seem suspicious that only one type of file format is always connected between two parties.
The strong steganographic algorithms thus acquire the ability to embed data in any type of file. This also solves the issue of not always being able to discover a proper image at the right moment, in the right format to help as a cover image.
Unsuspicious files − This condition include some characteristics of a steganographic algorithm that can result in images that are not used generally and can generate suspicion. Abnormal file size, for example, is one feature of an image that can result in more investigation of the image by a warden.
Hiding the data by taking the cover object as the image is known as image steganography. In digital steganography, images are widely used cover source because there are a huge number of bits present in the digital representation of an image. There are a lot of ways to hide information inside an image. Common approaches include:
In audio steganography, the secret message is embedded into an audio signal which alters the binary sequence of the corresponding audio file. Hiding secret messages in digital sound is a much more difficult process when compared to others, such as Image Steganography. Different methods of audio steganography include:
4: Video Steganography
In Video Steganography you can hide kind of data into digital video format. The advantage of this type is a large amount of data can be hidden inside and the fact that it is a moving stream of images and sounds. You can think of this as the combination of Image Steganography and Audio Steganography. Two main classes of Video Steganography include:
It is the technique of embedding information within network control protocols used in data transmission such TCP, UDP, ICMP etc. You can use steganography in some covert channels that you can find in the OSI model. For Example, you can hide information in the header of a TCP/IP packet in some fields that are either optional.

In digital steganography, images are widely used cover source because there are a huge number of bits present in the digital representation of an image. There are a lot of ways to hide information inside an image. Common approaches include:

In audio steganography, the secret message is embedded into an audio signal which alters the binary sequence of the corresponding audio file. Hiding secret messages in digital sound is a much more difficult process when compared to others, such as Image Steganography. Different methods of audio steganography include:

The advantage of this type is a large amount of data can be hidden inside and the fact that it is a moving stream of images and sounds. You can think of this as the combination of Image Steganography and Audio Steganography. Two main classes of Video Steganography include:

- Embedding data directly into the compressed data stream
It is the technique of embedding information within network control protocols used in data transmission such TCP, UDP, ICMP etc. You can use steganography in some covert channels that you can find in the OSI model. For Example, you can hide information in the header of a TCP/IP packet in some fields that are either optional.
