A year after its implementation in May 2011, the European Commission's Privacy and Electronic Communications Directive will finally start to be enforced as of tonight, meaning visitors to websites are required to be informed of, and given choice over, the site's intentions to store their data in cookies.
Though there has been fierce opposition to the directive, some companies, such as the BBC, Channel 4 and the Guardian, have now begun implementing measures that range from multiple user choices in the level of information shared with the site, to a single message informing the user that, by continuing to browse, they have automatically agreed to have their information stored.
But the majority of companies, it is widely reported, will miss tonight's deadline.
While the Information Commissioner's Office (ICO) still disagrees that a "one size fits all" policy of standardisation is not the way forward when enforcing cookie legislation, some believe such a framework is the only way forward.
Society for engineering and technology professionals, the Institution of Engineering & Technology said, "The implementation of this directive is likely to prove very variable until the introduction of a set of standards on the best way to provide a balance between easy browsing and personal privacy.
"We had hoped that more progress would have been made on achieving this in the 12 month implementation delay that the Information Commissioner, Christopher Graham, gave British organisations."
