- Steganography - Wikipedia
Steganography includes the concealment of information within computer files In digital steganography, electronic communications may include steganographic coding inside a transport layer, such as a document file, image file, program, or protocol Media files are ideal for steganographic transmission because of their large size
- 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" In BPCS-steganography true color images (i e , 24-bit color images) are

List of steganography techniques Steganography ( ˌstɛɡəˈnɒɡrəfi ⓘ STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection
- 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
- scikit-image - Wikipedia
scikit-image (formerly scikits image) is an open-source image processing library for the Python programming language [2] It includes algorithms for segmentation, geometric transformations, color space manipulation, analysis, filtering, morphology, feature detection, and more [3] It is designed to interoperate with the Python numerical and scientific libraries NumPy and SciPy
- Bacons cipher - Wikipedia
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 Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces)
- Visual cryptography - Wikipedia
Development of masks to let overlaying n transparencies A, B, printed with black rectangles reveal a secret image — n = 4 requires 16 (2 4) sets of codes each with 8 (2 4-1) subpixels, which can be laid out as 3×3 with the extra bit always black Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc ) to be encrypted in such a way that the
- Printer tracking dots - Wikipedia
Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was used to print the document
