On June 19th, 2020, the French Conseil d’État has ordered the Commission Nationale de l’Informatique et des Libertés (CNIL) in a court decision to dismiss particular provisions made in its Guidelines on the subject of cookies and other tracers, which it published in 2019.
The Conseil d’État has received several complaints by businesses and professional associations, who turned to the supreme court in order to have the CNIL’s Guidelines refuted.
The main focus of the decision was the ban on cookie walls. Cookie walls are cookie consent pages which, upon declining consent to the processing of the cookies used for the website, deny the user access to the website. In their Guideline on cookies and other tracers from 2019, the CNIL had declared that such cookie walls were not in accordance with the principles of the General Data Protection Regulation (GDPR), causing a lot of businesses to appeal such a provision in front of the Conseil d’État.
In their decision on the matter, the Conseil d’État has declared that the CNIL, as only having suggestive and recommendatory competence in data protection matters, did not have the competence to issue a ban on cookie walls in the Guidelines. The Conseil d’État focused on the fact that the CNIL’s competence was only recommendatory, and did not have the finality to issue such a provision.
However, in its decision, the supreme court did not put to question whether the ban of cookie walls was in itself lawful or not. The Conseil d’État refrained from giving any substantive statement on the matter, leaving that question unanswered for the moment.
The Conseil d’État has further stated in its decision that in the case of the ability of data subjects to give their consent to processing activities, it is indeed necessary, in order to form free and informed consent, that the data subject is informed individually about each processing activity and its purpose before giving consent. However, business have the margin to decide if they collect the data subject’s consent througha one time, global consent with specifically individualized privacy policies, or over individual consent for each processing activity.
In the rest of its decision, the Conseil d’État has confirmed the remainder of the CNIL’s guidelines and provision on the matter as being lawful and applicable, giving the complainants only limited reason to rejoice.

Today we are continuing our miniseries on contact tracing apps and data protection with Part 2 of the series: The EDPB Guideline on the Use of Contact Tracing Tools. As mentioned in Part 1 of our miniseries, many Member States of the European Union have started to discuss using modern technologies to combat the spread of the Coronavirus. Now, the European Data Protection Board (“EDPB”) has issued a new guideline on the use of contact tracing tools in order to give European policy makers guidance on Data Protection concerns before implementing these tools.
The Legal Basis for Processing
In its guideline, the EDPB proposes that the most relevant legal basis for the processing of personal data using contact tracing apps will probably be the necessity for the performance of a task in the public interest, i.e. Art. 6 para. 1 lit. e) GDPR. In this context, Art. 6 para. 3 GDPR clarifies that the basis for the processing referred to in Art. 6 para. 1 lit. e) GDPR shall be laid down by Union or Members State law.
Another possible legal basis for processing could be consent pursuant to Art. 6 para. 1 lit. a) GDPR. However, the controller will have to ensure that the strict requirements for consent to be valid are met.
If the contact tracing application is specifically processing sensitive data, like health data, processing could be based on Art. 9 para. 2 lit. i) GDPR for reasons of public interest in the area of public health or on Art. 9 para. 2 lit. h) GDPR for health care purposes. Otherwise, processing may also be based on explicit consent pursuant to Art. 9 para. 2 lit. a) GDPR.
Compliance with General Data Protection Principles
The guideline is a prime example of the EDPB upholding that any data processing technology must comply with the general data protection principles which are stipulated in Art. 5 GDPR. Contact tracing technology will not be an exeption to this general rule. Thus, the guideline contains recommendations on what national governments and health agencies will need to be aware of in order to observe the data protection principles.
Principle of Lawfulness, fairness and transparency, Art. 5 para. 1 lit. a) GDPR: First and foremost, the EDPB points out that the contact tracing technology must ensure compliance with GDPR and Directive 2002/58/EC (the “ePrivacy Directive”). Also, the application’s algorithms must be auditable and should be regularly reviewed by independent experts. The application’s source code should be made publicly available.
Principle of Purpose limitation, Art. 5 para. 1 lit. b) GDPR: The national authorities’ purposes of processing personal data must be specific enough to exclude further processing for purposes unrelated to the management of the COVID-19 health crisis.
Principles of Data minimisation and Data Protection by Design and by Default, Art. 5 para. 1 lit. c) and Art. 25 GDPR:
- Data processed should be reduced to the strict minimum. The application should not collect unrelated or unnecessary information, which may include civil status, communication identifiers, equipment directory items, messages, call logs, location data, device identifiers, etc.;
- Contact tracing apps do not require tracking the location of individual users. Instead, proximity data should be used;
- Appropriate measures should be put in place to prevent re-identification;
- The collected information should reside on the terminal equipment of the user and only the relevant information should be collected when absolutely necessary.
Principle of Accuracy, Art. 5 para. 1 lit. d) GDPR: The EDPB advises that procedures and processes including respective algorithms implemented by the contact tracing apps should work under the strict supervision of qualified personnel in order to limit the occurrence of any false positives and negatives. Moreover, the applications should include the ability to correct data and subsequent analysis results.
Principle of Storage limitation, Art. 5 para. 1 lit. e) GDPR: With regards to data retention mandates, personal data should be kept only for the duration of the COVID-19 crisis. The EDPB also recommends including, as soon as practicable, the criteria to determine when the application shall be dismantled and which entity shall be responsible and accountable for making that determination.
Principle of Integrity and confidentiality, Art. 5 para. 1 lit. f) GDPR: Contact tracing apps should incorporate appropriate technical and organisational measures to ensure the security of processing. The EDPB places special emphasis on state-of-the-art cryptographic techniques which should be implemented to secure the data stored in servers and applications.
Principle of Accountability, Art. 5 para. 2 GDPR: To ensure accountability, the controller of any contact tracing application should be clearly defined. The EDPB suggests that national health authorities could be the controllers. Because contact tracing technology involves different actors in order to work effectively, their roles and responsibilities must be clearly established from the outset and be explained to the users.
Functional Requirements and Implementation
The EDPB also makes mention of the fact that the implementations for contact tracing apps may follow a centralised or a decentralised approach. Generally, both systems use Bluetooth signals to log when smartphone owners are close to each other. If one owner was confirmed to have contracted COVID-19, an alert can be sent to other owners they may have infected. Under the centralised version, the anonymised data gathered by the app will be uploaded to a remote server where matches are made with other contacts. Under the decentralised version, the data is kept on the mobile device of the user, giving users more control over their data. The EDPB does not give a recommendation for using either approach. Instead, national authorities may consider both concepts and carefully weigh up the respective effects on privacy and the possible impacts on individuals rights.
Before implementing contact tracing apps, the EDPB also suggests that a Data Protection Impact Assessment (DPIA) must be carried out as the processing is considered likely high risk (health data, anticipated large-scale adoption, systematic monitoring, use of new technological solution). Furthermore, they strongly recommend the publication of DPIAs to ensure transparency.
Lastly, the EDPB proposes that the use of contact tracing applications should be voluntary and reiterates that it should not rely on tracing individual movements but rather on proximity information regarding users.
Outlook
The EDPB acknowledges that the systematic and large scale monitoring of contacts between natural persons is a grave intrusion into their privacy. Therefore, Data Protection is indispensable to build trust, create the conditions for social acceptability of any solution, and thereby guarantee the effectiveness of these measures. It further underlines that public authorities should not have to choose between an efficient response to the current pandemic and the protection of fundamental rights, but that both can be achieved at the same time.
In the third part of the series regarding COVID-19 contact tracing apps, we will take a closer look into the privacy issues that countries are facing when implementing contact tracing technologies.

Recently, the EDPB has adopted its Guidelines on processing of personal data through video devices (“the guidelines”). The guidelines provide assistance on how to apply the GDPR in cases of processing through video devices with several examples, which are not exhaustive but applicable for all areas of using video devices.
In a first step, the guidelines set the scope of application. The GDPR is only applicable for the use of video devices if
- personal data is collected through the video device ( e.g. a person is identifiable on basis of their looks or other specific elements)
- the processing is not carried out by competent authorities for the purposes of prevention, investigation, detection or prosecution of criminal offences or the execution of criminal penalties, or,
- the so-called “household exemption” does not apply (processing by a natural person in the course of personal or household activity).
Before processing personal data through video devices, controllers must specify their legal basis for it. According to the guidelines, every legal ground under Article 6 (1) can provide a legal basis. The purposes for using video devices for processing personal data should be documented in writing and specified for every camera in use.
Another subject of the guidelines is the transparency of the processing. The controllers have to inform data subjects about the video surveillance. The EDPB recommends a layered approach and combining several methods to ensure transparency. The most important information should be written on the warning sign itself (first layer) and the other mandatory details may be provided by other means (second layer). The second layer must also be easily accessible for data subjects.
The guidelines also deal with storage periods and technical and organizational measures (TOMs). In some member states may be specific provisions for storing video surveillance footage, but it is recommended to – ideally automatically – delete the personal data after a few days. As with any kind of data processing, the controller must adequately secure it and therefore must have implemented technical and organizational measures. Examples provided are masking or scrambling areas that are not relevant to surveillance, or the editing out of images of third persons, when providing video footage to data subjects.
Until September 9th 2019, the guidelines will be open for public consultation and a final and revised version is planned for the end of 2019.

As Bloomberg reports, the Article 29 WP will provide guidance on the GDPR soon. Isabelle Falque-Pierrotin, Chairwoman of the CNIL as well as of the Article 29 WP, acknowledged that the GDPR text is ambiguous in some aspects. Therefore, these guidelines aim at serving as an operational toolbox.
Amongst others, the guidance to the GDPR shall refer to the following aspects:
- The designation of the leading Supervisory Authority in case of complaints or in relation to other procedures. Moreover, aspects of the bilateral cooperation and competence to resolve disputes by the Supervisory Authorities and the European Data Protection Board shall be clarified.
- Guidance on the figure of Data Protection Officers is one of the priorities of the Article 29 WP, as it will play an essential role in companies on achieving GDPR compliance.
- The right to data portability has been regulated for the first time in the GDPR. This right will allow data subjects to access their data and transfer data to other data controllers, for example upon the change of telephone provider. The guidance should focus on its scope and implementation.
- The standard by which the proof of consent will take place, will have to be specified. This is especially important for small and medium-sized companies, for which a “simple pedagogical tool” will be developed.
- A formal guidance on the Privacy Shield will not take place until the EU Commission has reviewed its functioning after the first year, this is summer or early fall 2017.
At the moment, the Article 29 WP remains neutral with regard to the Brexit. However, Falque-Pierrotin remarked that the Privacy Shield may be also useful in UK regarding international data flows with the U.S.A.
Further guidance is also expected in 2017, especially regarding topics such as the EU-U.S. Privacy Shield and the implication of the Brexit in privacy issues.
