What is Steganography

1.

It has many algorithms not just for having a secret message, but also to have a correct message. The way of embedding a confidential message in media (audio, text, image, video), without change in the host signal, and it is one of the essential ways to hide information.

2.

Associated to a data hiding technique for hiding an important message or secret data into digital media. The hidden data is not visible, and the image with the hidden data is called a stego-image. Learn more in: Digital Watermarking Techniques

3.

It is a technique to provide security to the secret information using data hiding technique. In steganography, a cover media is selected to hide the information. Depending on the place of data hiding it is mainly divided into two categories: Spatial domain- if information is embedded directly in the pixel values and Transform domain- if information is embedded in the coefficient values which are calculated from the pixel values of the cover image.

4.

Steganography is the art of concealed communication: the very existence of the message is a secret. Steganography is the study of techniques for hiding the existence of a secondary message in the presence of a primary message. Learn more in: Digital Watermarking

5.

The technique to hide the secret message into the cover object to realized the covert communication without being found by the third part, which can conceal the existence of the communication itself. Learn more in: Adaptive Image Steganography Based on Structural Similarity Metric

Steganography is a method to hide data in a cover media so that other persons will not notice that such data is there. Learn more in: A Survey of Information Hiding

9.

This is an area where a signal (any kind of data) can be inserted into host signal (generally Image) to hide. Only host signal is visible after the process. Learn more in: Utilizing Image Color Channels for High Payload Embedding

10.

The technology to realize secret communication by hiding secret information into such carrier as image, video, audio, text, computer program, and so forth. The carrier is public, while the existence of secret information is secret. Learn more in: Multimedia Content Protection Technology

11.

Covered writing; it is a study of concealing the existence of a message. Learn more in: Digital Watermarking and Steganography

12.

Watermarks may be for wide spread use. But a modification for that is steganography, where the transmitting end communicates a secret message embedded in the digital signal to the receiver. The main objective is to add owner descriptive information or any other form of authenticating information to the signal concerned, such that is difficult to remove. Moreover, to covert communication between individuals, some hidden embedded information could be used as well. Learn more in: Watermarking of Data Using Biometrics

The art of hiding secret data inside other innocent media file. Learn more in: Digital Steganography Based on Genetic Algorithm

15.

The art and science of writing hidden messages in such a way that no one apart from the sender and the intended recipient even realizes that there is a hidden message. Learn more in: Anonymous Communications in Computer Networks

16.

A practice of concealing a file, image, message, or video within another one of such. From Greek portmanteau steganographia (steganós (ste?a???) – “covered or concealed”, graphia (??af?) – “writing”). Learn more in: Universal Code of Movies and Influence of Traditional Media

Steganography is a class of information hiding that deals with concealing very the existence of the hidden message. Learn more in: Critical Analysis of Digital Steganography

18.

The art and science of encoding hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. It is a form of security through obscurity. Learn more in: Data Hiding Schemes Based on Singular Value Decomposition

19.

Techniques that allow secret communication, usually by embedding or hiding the secret information (called embedded data) in other, unsuspected data. Steganographic methods are based on the assumption that the existence of the covert communication is unknown and they are mainly used in secret point-to-point communication between trusting parties. As a result, steganographic methods are usually not robust, that is the hidden information cannot be recovered after data manipulation. Learn more in: Music Score Watermarking
