Copyright Management and Control Systems: Post-Infringement 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. |

Like that car? The tricks of the data body industry 2. Like that car? The tricks of the data body industry In the New Economy, data have become a primary resource. Businesses unable to respond to the pressure of informatisation are quickly left behind. "Information is everything" has become the war-cry of the New Economy. More than ever, business companies now collect data related to their customers, their competitors, economic indicators, etc., and compile them in However, there are also many companies that specialise in data body economics as the main line of business. They collect huge amount of data process and enhance them (thereby increasing the value of the data) and offer them on to other companies. For example, somebody who has been attracted by a car on display in an airport terminal and completes a card with name and address to participate in a draw reveals a lot of economically valuable information about him / herself. Apart from name and address, and other data that is completed on the card, this person also can be assumed to be a potential car buyer (evidently he / she wants a car) and to be relatively affluent (the poor do not normally travel by plane). The time when you complete the card also provides information: in July and August, you are more likely to be a holiday maker than in November. Possibly in small print somewhere on the ticket you complete you agree to receive more information about this and other products, and you agree also that your data are "electronically processed". The data acquired this way can normally be expected to be much more valuable than the car the is offered in the draw. Most people who completed the cards will not win in the draw, but instead end up on directs marketing data warehouses and one day receive offers of products and services which they never knew they wanted. |

Data mining In data mining, data are analysed for relationships among them that have not yet been detected. This is a process used in scientific research as well as in marketing and administration. Through data mining, new surplus data can be generated out of a given quantity of data. A good general introduction to data mining and further links can be found at the |
