(2) original source can be determined and demonstrated if part of the document is claimed by somebody else, copied without permission, etc. Snowdrop uses redundant steganography using four different logical channels, and should be proof to many modifications, including reformatting, spell checking and so on. . This package is useful in forensic investigations and security actions. It provides three commands: sd-eng, sd-engf and sd-c. sd-eng and sd-engf provide watermarking for draft-quality and fine-quality English language text documents, respectively, whereas sd-c provides experimental C source code watermarking. . Warning: Snowdrop is currently in beta, and may produce bad or corrupted results, especially when run on C source code.
