Steganography
Applied to electronic files, steganography refers to the process of hiding information in files that can not be easily detected by users. Steganography can be used by intellectual property owners in a variety of ways. One is to insert into the file a "digital watermark" which can be used to prove that an infringing file was the creation of the copyright holder and not the pirate. Other possibilities are to encode a unique serial number into each authorized copy or file, enabling the owner to trace infringing copies to a particular source, or to store
Agents
Agents are programs that can implement specified commands automatically. Copyright owners can use agents to search the public spaces of the Internet to find infringing copies. Although the technology is not yet very well developed full-text search engines allow similar uses.
Copyright Litigation
While not every infringement will be the subject of litigation, the threat of litigation helps keep large pirate operations in check. It helps copyright owners obtain relief for specific acts of infringement and publicly warns others of the dangers of infringement.

GCHQ is the British Government Communication Headquarters, which is in fact an electronic monitoring centre which intercepts communications using spy satellites, listening devices and code-cracking equipment. The 1994 Intelligence Services Act defines GCHQ's role in the post Cold War world. National security, economic well-being and the prevention and detection of serious crime are its headline interests. It routinely gathers information on drug-dealing, terrorism, and the movement of arms and key resources such as oil, but is also said to be heavily involved in ECHELON. GCHG praises itself to use and design high end technology such as Cray systems, Tandem based storage and high-end workstations, as well as software for Signals Analysis, Complex Data Manipulation, Translation and Transcription.
