The art of writing in cipher, or in characters which are not intelligible except to persons who have the key; cryptography.
The branch of cryptography in which messages are hidden inside other messages; -- used commonly for the process of hiding messages inside a computerized image file, as for example hiding the name and copyright notice of the owner of an image as protection against violation of the copyright.
Art and science of conveying information in such a way that its presence is unnoticed. It comes from the greek words steganós steganos (covered) and graptos graptos (writing), literally covered writing, in the sense of a hidden thing. In steganography the text or image in question is invisible although it resides in the interior of an apparently normal piece of other information, like a text an image or a soundtrack. Unlike cryptography where the message is clearly visible although you need the key to decipher it, in this case the information cannot be seen unless the correct procedure is applied to the text or image where it resides.
The science of hiding data in seemingly innocuous formats such as pictures, audio, or video.
A method of embedding electronic messages into a media file (for example, an image of audio file) by altering nonessential lines of code. The changes are imperceptible and the message remains undetected until unencrypted.
Encoding something so the fact that an encoded document exists is hidden. An example of this is software that allows hiding text within computer graphics.
Steganography makes it possible to hide secret data among other data. Graphics, for instance, can hide text messages, or images can be inserted in a sound file.
The science of hiding the existence of a message, as opposed to cryptography, which is the science of hiding the meaning of a message.
Hiding a secret message by concealing it within another medium, such that the secret message is undetectable unless you know to look for it. For example, a message might be hidden within an image by changing the least significant bits to be the message bits..tôp.
the hiding of information inside other information.
Steganography is basically hiding information in plain sight. Steganography, is used to hide information in computer files. Information can be generally hidden in various file formats, such as: images, audio files, text files and Word documents.
A technology that makes it possible to embed hidden information in documents, pictures, and music files ñ and send them undetected over the Internet.
the encoding of data to conceal the existence of a message. For example, steganographic watermarks may identify the owner of a digital image yet not impair its viewing. Learn more about software steganography here.
The concealment of the existence of messages. This can take the form of hiding text within a picture or within a word processing file the contents of part of which are concealed (and see footnote)
the process of hiding data inside other data. For example, within an image or a sound file. By looking at the image, or listening to the sound, you would not know that there is extra information present. Cryptographers may apply steganography to electronic communications. Computers have greatly opened this field by giving the ability to conceal information within picture files used on the Internet.
takes one piece of information and hides it within another. Computer files (images, sounds recordings, even disks) contain unused or insignificant areas of data. Steganography takes advantage of these areas, replacing them with information (encrypted mail, for instance). The files can then be sent or transported without anyone knowing what really lies inside of them. For more information go to http://security.tao.ca/stego.shtml
To hide data inside other data.
Hiding one kind of information inside a different medium - for example packing a text message inside a graphic file.
The practice of concealing the existence of a message. This differs from cryptography, which hides the meaning of a message rather than the message itself.
The art of concealing a message's existence. One example would be through the use of photographic microdots.
A technique for hiding data or program code within an image file by scattering fragments throughout the file. The image will open quite normally within programs such as Internet Explorer or Adobe Photoshop, but the hidden data can be extracted using special utilities.
The process of hiding data inside other data. For example, a text file could be hidden "inside" an image or a sound file. By looking at the image, or listening to the sound, you would not know that there is extra information present.
The science of communication in a way that hides the existence of the communication.
Methods of hiding the existence of a message or other data. This is different than cryptography, which hides the meaning of a message but does not hide the message itself. An example of a steganographic method is "invisible" ink.
Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message; this is in contrast to cryptography, where the existence of the message itself is not disguised, but the content is obscured.
