The Office of the Information Commissioner has pledged its support for opt-in cookies, despite a recent u-turn on such standards by the European Union.
Electronic tags, known as cookies, can be used to track an individual's movements on the Internet for a number of years. The information commissioner is concerned that the unauthorised use of such intrusive technology could breach data protection principles within the UK.
"If organisations are going to put lots of computer code on a machine that tracks a person's movements online, individuals should be told about it," said Iain Bourne, strategic policy officer to the information commissioner. "This shouldn't be happening until they have agreed to it."
Cookies are small pieces of code used mainly by commercial Web sites to track users' behaviour online. They are downloaded to browsers and used to recognise and authenticate users when they return to a Web site so they don't have to log in every time. The electronic tags are also able to hold personal information such as passwords for custom e-tail services, and Web-based email.
"An individual's agreement is the best basis for doing anything. Whatever happens in the EU, this will remain our position," said Bourne. The Office hopes that within time, opt-in cookies will become a pan-European standard.
The Office will await the pending European vote on the draft directive before deciding on a cookie standard for the UK. "We have our own views under the Data Protection Act, which we are responsible for enforcing," said Bourne. "We cannot legally enforce things that are not in statute, but we can take our own view on good practice regardless."
