Throughout history, knowledge has meant power, and how knowledge resources have been shared, distributed or monopolised has told us much about the nature of the societies in which these have occurred. But the brave new post-Internet world is changing many of the presumptions and rules which allowed knowledge to be controlled earlier. By opening up vast areas of communication and permitting the sharing of information even by those not "authorised" to do so, or between those who may never meet in any other sense, it is permitting a new proliferation of both knowledge and information th at was unprecedented earlier.
 
But the current freedoms in cyberspace are already being subjected to new forms of control, and how it will finally end up is still anybody's guess. At the same time, even as those people who are fortunate enough to be "connected" - still very much a small minority of the world's population - have instantaneous access to all kinds of information, they in turn are revealing more about themselves than they know. For many in the developing world, the problem is already so acute that there are citizens' movements trying to control it, as the most intimate details of their existence are tracked and stored as data, to be used whenever it suits those who h ave this data.
 
These Orwellian Big Brothers at present are not all-controlling states determined to define and regulate their hapless subjects, but large private corporations which seek to use such data in their advertising campaigns, or to influence consumer choices in other ways. This is not to say that they do not also try to define and regulate people, or that states will not eventually also use such information for control. But the driving force currently is private profit rather than state oppression, the need is for insidious influence rather than overt control. In countries of the developed West, there is already a major concern about individual privacy, as it becomes apparent that both employers and omniscient web sites and advertising networks can track every move that is made in cyberspace.
 
A survey of nearly a thousand large companies conducted last year by the American Management Association found that nearly half of them monitored the e-mail, computer files or phone calls of their workers. There are computer software packages that can monitor and record every keystroke on the computer, screen all incoming and outgoing e-mail for certain keywords and can forward suspicious messages to a supervisor for review. E-mail can be resurrected from computer hard drives even after it has ostensibly been deleted. And employers are increasingly monitoring jokes and e-mail sent from home as well as work over company servers.
 
But the most graphic example of the faceless company picking up detailed private information is in the case of Double Click Inc., which is the Internet's largest advertising company. For several years now, Double Click has been compiling detailed information on the browsing habits of millions of web users by placing "cookie" files on hard drives. Cookies are electronic footprints that allow web sites and advertising networks to monitor online movements, including information such as the search terms that are entered as well as the articles that are skimmed and how long they are skimmed for. This had allowed Double Click to help its 2,500 clients to work out what kind of targeted advertising to provide to each individual surfer who visits their particular web sites. Thus, if you have been visiting a lot of music sites, ads for music will dominate when you click on a search engine like AltaVista. Similarly, if your apparent interest is in cars, then a new model from Ford may greet you on the home page of some other web site.
 
All this seemed quite harmless, even more efficient and advantageous, as long as users were confident that their virtual identities were not being traced to their actual identities. However, in November 1999, Double Click bought Abacus Direct, which is a database of names, addresses and information about off-line buying habits of 90 million households, compiled from the largest direct mail catalogues and retailers in the nation. Then, in January 2000, Double Click began compiling profiles linking individuals' actual names and addresses to Abacus' detailed records of their online and off-line purchases. People who are fortunate enough to be 'connected' have instantaneous access to all kinds of information but they, in turn, are revealing more about themselves than they know. This naturally meant that apparently "anonymous" online shopping was effectively being archived in personally identifiable dossiers. But it also meant that all the Internet-related activities of that person were now known, from personal e-mail to all the sites visited.
 
This led to substantial pressure from privacy advocates (inevitably Internet-based!) as well as from dot.com investors. As a result, Double Click has recently announced that it will postpone its profiling scheme until the United States government and the e-commerce industry agree on privacy standards. But this is of course only one of the many such schemes that are now delving more and more into various details of personal existence, for a varied range of reasons. Such schemes are assisted by new technologies that allow for ever more prying into the l ives of the connected. Thus, Globally Unique Identifiers, or GUIDs, are making it possible to link every document that is created by one user with the messages he/she e-mails, the chats that are posted and the various web sites that are browsed. These GUIDs then becomes a kind of serial number that can be linked with the name and e-mail address whenever that user registers online for a product or service.
