The ability to inexpensively and quickly collect, maintain, manipulate and transfer data enables every individual and organization to collect millions of personal records. When visiting a commercial site, chances are the site installs a little file, a ‘cookie’, on your computer’s hard disk. This file helps track every click you make on that site, so companies specializing in consumer profiling can learn your shopping and buying habits. When you you collect a prescription, the chemist collects details about you. Before you send a warranty card for a newly purchased product, you are asked to answer some few questions that have nothing to do with the warranty but much to do with your lifestyle. All these data are channeled into a large database for commercial exploitation. Your control for such data is minimal. While consumers, patients and employees might consent to the collection of information on on aspect of their lives by one party and on another aspect by another party, the combination of such information might reveal more than they would like. For a firm can easily and inexpensively purchase your data from a chemist and several consumer goods companies, combine the data into larger records and practically prepare a dossier about you: the medicines you take (and through this information, the diseases you might have); the political party to which you contributed; and so on.Civil rights advocates argue that IT has created a Big Brother society where anyone can be observed. US business leaders oppose European-style legislation to curb collection and dissemination of private data because this limits target marketing and other economic activities. Business leaders ask ‘How can we target our products to consumers who are most likely to want them if we have no information about those consumers?’ Are you willing to give up some of your privacy to help companies better market to you products and services you might be interested in? Do you accept the manipulation and selling of your personal data?
