Cookies and similar technologies

Techniques other than cookies are often used in an attempt to circumvent the data protection related obligations. Therefore, all the following technologies fall under the category cookies and similar technologies

• Cookies
• Scripts (such e.g. JavaScript code) and components (such as browsers plug-ins) to be executed on the client side
• Web caching mechanisms
• HTML5 local storage
• “Device fingerprinting”
• “Canvas fingerprinting” and “Evercookies”
• Web beacons

Cookies and similar technologies requiring consent

Cookies and similar technologies that generally DO need consent

• Social plug-in tracking mechanisms
• Third party advertising cookies
• Analytics cookies (except for the exemption described further below)

Cookies and similar technologies that generally do NOT need consent

• User input cookies, for the duration of a session
• Authentication cookies, for the duration of a session
• User centric security cookies, used to detect authentication abuses and linked to the functionality explicitly requested by the user, for a limited persistent duration
• Multimedia content player session cookies, such as flash player cookies, for the duration of a session
• Load balancing session cookies, for the duration of a session
• User interface customisation cookies, for a browser session or a few hours, unless additional information in a prominent location is provided (e.g. “uses cookies” written next to the customisation feature)

Exceptionally, Data Protection Authorities consider that, due to the low risk for users, prior consent can be skipped in case of first party cookies used for anonymous, aggregate statistics under specific assumptions and safeguards. The web service must although provide the user with a simple, easy-to-use functionality to “opt out” from analytics.

The EU institution must adequately inform users and obtain their consent before setting cookies and any other technology falling within the scope of Article 5(3) of the ePrivacy directive. By default, none of those cookies must be set.

• For all Commission owned websites within the europa.eu domain, consent is managed centrally on domain level by implementing the Cookie Consent Kit. The consent indicated via the mandatory cookie consent kit covers the domain europa.eu.
• All cookies within the europa.eu domain, placed by Commission-owned websites, are described on the Commission central cookie policy page: Cookies policy (europa.eu)

Regarding the actual cookies on a specific site, the site owner has to check whether the cookies used are already mentioned on the corporate cookies page. If not, DG COMM should be contacted with an inventory of all first- and third-party cookies providing information on their purpose, the type of data collected, stored or transmitted by cookies, and the lifetime of the cookie.

These procedures are dedicated to external and internal developers and web masters of the European institutions. Consequently, features documented below are tailored to the European Commission's content management systems and internal guidelines.

Implementing user consent should be done by implementing the Cookie Consent Kit.

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 website.

This solution provides the following functionalities

• JavaScript to display automatically 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
