There is a lot of fear on the Internet that cookies will damage your hard drive, copy your data or reveal your secret super hero identity. But this is not true. cookies are not dangerous. According to the Computer Incident Advisory Capability (CIAC)
In this case, the cookie isn't the problem, it's that you gave information to that website.
Of course, IDS's magic cookies will be of little use if the unemployed person, unable to afford a PC or ISP account, has to use the PC in the public library. IDS is an idiot.
BTW, not exactly 'real' cookies, but one reason why I won't have Adobe (Macromedia) Flash on my system any more:-
"United Virtualities is offering online marketers and publishers technology that attempts to undermine the growing trend among consumers to delete cookies planted in their computers.
According to JupiterResearch, a division of Jupitermedia Corp., 58 percent of Internet users have deleted [their normal web browser] cookies, essentially making many consumers anonymous during site visits. In addition, 39 percent of consumers are deleting cookies from their primary computer monthly.
United Virtualities's PIE helps combat this consumer behavior by leveraging a feature in Flash MX called local shared objects. Flash MX is a Macromedia Inc. application for developing multimedia Web content, user interfaces and Web applications. The technology runs on a Flash Player that the company says is deployed on 98 percent of Internet-capable computers.
When a consumer goes to a PIE-enabled website, the visitor's browser is tagged with a Flash object that contains a unique identification similar to the text found in a traditional cookie. In this way, PIE acts as a cookie backup, and can also restore the original cookie when the consumer revisits the site.
While consumers have learned to delete cookies, most are unaware of shared objects, and don't know how to disable them.
Mookie Tanembaum, founder and chief executive of United Virtualities, says the company is trying to help consumers by preventing them from deleting cookies that help website operators deliver better services.
"The user is not proficient enough in technology to know if the cookie is good or bad, or how it works," [CEO] Tanembaum said."
