However, there are actually several cookies set on visiting the website, notably from Facebook, Twitter, Google, YouTube and the UIDAI itself.
These cookies can allow the sites setting them to track information on people visiting the UIDAI website. While the use of such cookies is common, the legal way to use them is to disclose that they are in use and the kind of data they collect and for what purpose. Nor is it necessary that cookies are used for spying or profiling. A cookie is simply a line of text stored in the browser that is sent to the server with each request. While it could be used to store identifiable data, and Facebook has faced criticism in the past for tracking user behavior, it can also store simple non-identifiable session information that makes the usage of the site easier.
Clearing the cookies and returning to the page still resulted in these cookies being set.
This is basically yet another example of UIDAI making tall claims – in this instance the assurance of not tracking any information at all by not using any cookies – that the quality of its technological practices cannot fulfill.
The UIDAI should have responsible disclosure of data collection they allow. And not just about cookie usage.
