Today the Article 29 Working Party ("WP29") published a working document on how consent for cookies may be obtained. The WP29's opinions and working documents provide authoritative guidance on EU data protection rules.
The WP29 advises that a website should contain a mechanism that satisfies each of the following main elements for valid consent:
- consent must be specific and based on appropriate information, including e.g. the purposes of the cookies;
- consent must be provided before the cookies are set or read;
- a positive response or other active behavior of the user is required; and
- on the entry page the user should be provided with a real and meaningful choice to freely accept all, some or no cookies.
- Consent mechanism
According to the WP29, a website should contain:
- an immediately visible notice informing whether various types of cookies are being used, providing the information in a so-called 'layered approach';
- an immediately visible notice informing that by using the websites, the user agrees to cookies being placed and read by the websites;
- information explaining how the user can express and later withdraw cookie consents;
- a mechanism by which the user can choose to accept all or some or decline cookies; and
- an option for the user to subsequently change a prior preference regarding cookies.
- Layered approach to information and consent
The WP29 in this working document confirms the notion of layered information approach (information to be provided layer by layer upon request of the user) and various consent options as introduced in previous documents. In this working document, the WP29 confirms that a user should not only be informed about the various categories of cookies, but also be able to choose which categories it allows or declines.
Furthermore, the WP29 advises that access to a website should not be made conditional on acceptance of all cookies. If the user does not accept cookies, the user should not be denied access, but may be offered access to less content of the website.
- Tracking cookies
Specific mention is made of tracking cookies. When tracking cookies are being used to single people out, such as by creating profiles based on behaviour, such data likely are personal data according to the WP29. The WP29 advises that for the processing of such personal data together with reading and setting of tracking cookies, the unambiguous consent ofthe user is obtained. Whether such consentis validly obtained will be assessed by the competent national data protection authorities
With the guidance provided in this working document, the national authorities will have practical guidelines to verify compliance and enforce the rules regarding consentfor cookies.
