	Integrated circuit devices with steganographic authentication and steganographic authentication methods - Patent # ...
		Steganographic communication is a method of communication that hides the existence of the communication.
		The steganographic communication constituting the authentication is embodied in the following aspectsof this communication: (1) the terminal knew to ask for a particular file ABC, and (2) the terminal knew to request one half of the available information about that particular file.
		Steganographic authentication is easier to administer and implement because it need not have any special dedicated cryptographic hardware or software.

	Associating data with images in imaging systems patent invention (Site not responding. Last check: 2007-11-02)
		In one embodiment, the steganographic data is embedded in the media signal as part of the process of uploading it to a network.
		Steganographic methods can encode data in an image, including identifiers and references that associate the image with additional data stored outside the image itself.
		In some applications, the capacity of the images to hold a steganographic signal, such as an imperceptible watermark, is sufficient to store the data associated with the image.

	Steganography...Forensico.com
		Generally a steganographic message will appear to be something else, like a shopping list, an article, a picture, or some other "cover" message.
		Steganographic messages are often first encrypted by some traditional means, and then a covertext is modified in some way to contain the encrypted message, resulting in stegotext.
		The payload is the data it is desirable to transport (and, therefore, to hide).

		One fact that most people forget is that having a utility on one's machine is a blatant clue that the user has steganographically encoded material within their files, and gives a starting point for forensic investigators.
		Pattern matching-visual analysis of patterns or artifacts left from steganographic applications, involving comparison of the original carrier or a discovered generalization in steganography to a carrier with an embedded message.
		Usually a balance between preserving the integrity of the carrier and removing or distorting the embeddedmessage is the desirable outcome of this attack.

	SoftwareShield Press Releases
		“Steganographic licensing technology” is SoftwareShield’s licensing and copy protection solution which gives developers the unique and interesting option of using encrypted data hidden in images to license and protect their applications.
		The SoftwareShield steganographic engine performs the task of hiding license data inside images so effectively that thousands of bytes of data can be hidden in a small image without it appearing altered to the human eye.
		To illustrate how effective the SoftwareShield steganographic algorithm is at hiding license data, we have embedded two paragraphs of text (about 150 words) inside the following logo.

	Linking of computers based on steganographically embedded digital data - Patent 6542927 (Site not responding. Last check: 2007-11-02)
		steganographically embedding the data object in a second object comprising at least one of audio and visual data, said embedding occurring in-band within said audio or visual data, rather than in a part of said second object not intended for presentation to a user;
		The method of claim 4 in which said second object is originally in digital form when steganographically embedded, but is thereafter rendered into human-perceptible form, converted back into digital form, and decoded, wherein said rendering into human-perceptible form, and subsequent conversion back into digital form, does not prevent decoding of the steganographically embedded data object.
		Conventional business cards can be steganographically encoded with Bedoop data, e.g., by texturing, watermark tinting, ink-jet splattering, text steganography, etc. As with many of the earlier-described embodiments, the steganographic encoding is tailored to facilitate decoding in the presence of arbitrary rotation or scale distortion of the card introduced during scanning.

	"Shake-speares Sonnets" Cryptogram.
		Given what is to follow, it is rather interesting that the example texts chosen by Bacon in the explication of his method of steganographic "bi-literarie" ciphering are associated with Caesar, "cypher'd staff", and delivery of a message by means of a Spear.
		The claim of a steganographically concealed cryptogram in the Sonnets frontmatter should be viewed and judged in the context of the popularity and availability of cryptographic information prior to (and after) the publication of the Sonnets.
		The headpiece is a steganographic pictorial cryptogram which contains (at least) two instances of the name "Bacon" in the form of rebuses.

	EasyBMP Cross-Platform Windows BMP Library: Steganography Code Sample
		The core of any steganographic method is how it encodes a single byte (8 bits) of information within the image.
		In practice, such methods are impossible to detect visually but easy to detect with a computer: if the file size is larger than the minimum size necessary for the image size and color depth (according to the file format specification), then it probably included hidden data.
		Other steganographic methods hide data by slightly modifying the pixels of the actual image by small amounts.

		This won't stop the technologically adept at scanning the image at home and altering it in Photoshop to remove the watermark by blurring or skewing the image, but it does help to protect Wal-mart and Kodak from legal backlash if a copyrighted image is duplicated.
		While they can test the file for known steganographic algorithms, there is no guarantee that the perpetrator didn't use a new or undetectable method of hiding data.
		Since the use of any program causes data to be written to the hard drive and into memory, it is possible to extract data from these sources, thus bypassing any and all security offered by the encryption and steganography process.

		The method the author discusses hinges upon a well known steganographic implementation, low-order bit flipping in graphic images.
		This allows one to use a picture or a sound file and hide data, resulting in a small bit of hopefully unnoticeable noise in the data and a safely hidden cache of data that can later be extracted.
		A message in which each byte has a bit which is significant to the steganographically hidden message can be extracted with ease relative to a message in which there are 10 possible bytes for each bit of each character.

	REU Summer 2002 Symposia, Aladdin Center
		A recent paper by Hopper, Langford and von Ahn gives the first steganographic protocols which have rigorous proofs of security.
		The authors show several constructions and prove that if certain cryptographic primitives exist, then these constructions can be instantiated by steganographically secure protocols.
		These protocols are also unusual in that they are the first known protocols (provably secure or not) that can hide information in unformatted, plain text.
