I just received the following e-mail from [email protected] mailed by scoutcamp.bounces.google.com:

Dear Publisher,

We want to let you know about a new policy about obtaining EU end-users’ consent that reflects regulatory and best practice guidance. It clarifies your duty to obtain end-user consent when you use products like Google AdSense, DoubleClick for Publishers and DoubleClick Ad Exchange.

Please review our new EU user consent policy as soon as possible. This requires that you obtain EU end users’ consent to the storing and accessing of cookies and other information, and to the data collection, sharing and usage that takes place when you use Google products. It does not affect any provisions on data ownership in your contract.

Please ensure that you comply with this policy as soon as possible, and not later than 30 September 2015.

If your site or app does not have a compliant consent mechanism, you should implement one now. To make this process easier for you, we have compiled some helpful resources at cookiechoices.org.

This policy change is being made in response to best practice and regulatory requirements issued by the European data protection authorities. These requirements are reflected in changes that have been recently made on Google’s own websites.

Thank you in advance for your understanding and cooperation.

Regards,
The Google Policy Team

The site cookiechoices.org is operated by Google and links to the cookie consent kit on the website of the European commission.

The cookie consent solution is a JavaScript‑based kit that, after some site‑specific configuration, will automatically add a header banner to the page. This header banner will disappear once the user has accepted or refused the cookies used on the site.
This solution provides the following functionalities:

• JavaScript to automatically display the header banner in 24 languages
• a wizard to declare your cookies and the link to your cookies notice page
• a JavaScript API with methods and functions that help to prevent prior storage of cookies
• a corporate‑consent cookie to remember the choice of the user across websites
• a template for the cookie notice page.

This is a central service: you have to include the JavaScript file on your website and add a one‑site‑specific configuration file listing the cookies you are using. You will also have to add a short HTML parameter to every element in your site that sets a cookie.

Read more about the Cookie Consent Kit in the documentation. The European Commission has a step-by-step guide to get started to comply with the cookie laws.
