Digital messages Image of a tree with a steganographically hidden image The hidden image is revealed by removing all but the two least significant bits of each color component and a subsequent normalization The hidden image is shown below Image of a cat extracted from the tree image above
- Steganography tools - Wikipedia
Steganography architecture example - OpenPuff A steganography software tool allows a user to embed hidden data inside a carrier file, such as an image or video, and later extract that data It is not necessary to conceal the message in the original file at all
- Bacons cipher - Wikipedia
Bacon's cipher Image of Bacon's cipher Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605 [1][2][3] In steganography, a message is concealed in the presentation of text, rather than its content
- Steganalysis - Wikipedia
Steganalysis is the study of detecting messages hidden using steganography; this is analogous to cryptanalysis applied to cryptography
- Steganographic file system - Wikipedia
Steganographic file systems are a kind of file system first proposed by Ross Anderson, Roger Needham, and Adi Shamir Their paper proposed two main methods of hiding data: in a series of fixed size files originally consisting of random bits on top of which 'vectors' could be superimposed in such a way as to allow levels of security to decrypt all lower levels but not even know of the existence
- BPCS-steganography - Wikipedia
BPCS-steganography (Bit-Plane Complexity Segmentation steganography) is a type of digital steganography Digital steganography can hide confidential data (i e secret files) very securely by embedding them into some media data called "vessel data " The vessel data is also referred to as "carrier, cover, or dummy data"
- OpenPuff - Wikipedia
OpenPuff Steganography and Watermarking, sometimes abbreviated OpenPuff or Puff, is a free steganography tool for Microsoft Windows created by Cosimo Oliboni and still maintained as independent software The program is notable for being the first steganography tool (version 1 01 released in December 2004) that: lets users hide data in more than a single carrier file When hidden data are split
