General Comments

The sudden outbreak of cases of COVID-19-afflictions ("Corona-Virus"), which was declared a pandemic by the WHO affects data protection in various ways. Different data protection authorities published guidelines for employers and other parties involved in the processing of data related to the Corona-Virus (read more below).

The Corona-Virus has also given cause to the use of different technologies based on data collection and other data processing activities by the EU member states and private companies. These processing activities mostly focus on preventing and slowing the further spreading of the Corona-Virus and on monitoring the citizens' abidance with governmental measures such as quarantine. Some of them are based on anonymous or anonymized data (like for statistics or movement patterns), but some proposals also revolved around personalized tracking.

At the moment, it is not easy to figure out, which processing activities are actually supposed to be conducted and which are only rumors. This page will therefore be adapted once certain processing activities have been confirmed. For now, this article does not assess the lawfulness of particular processing activities, but rather outlines the general conditions for data processing in connection with the Corona-Virus.

It must be noted that several activities - such as monitoring, if citizens comply with quarantine and stay indoors by watching at mobile phone locations - can be done without having to use personal data under Article 4(1) GDPR, if all necessary information can be derived from anonymised data. The GDPR does not apply to activities that only rely on anonymised data.

Principles of Article 5 GDPR

Regardless of the exceptional situation, data processing activities in connection with measures against the Corona-Virus that rely on personal data (Article 4(1) GDPR) have to comply with the principles of data processing as lined out in Article 5 GDPR (read more). As a situation like the Corona-Outbreak will often allow processing under different legal basis (see below), the main element to contain disproportionate processing, are the principles in Article 5:

  • Lawfulness, fairness and transparency: Data processing must be lawful under Article 6 GDPR and/or Article 9 GDPR. Some member states have already passed laws that deal with the Corona-Virus which must be taken into consideration when assessing the lawfulness of processing. See below for more information. Furthermore, processing must be fair and transparent. This includes i.e. that data subjects whose data is being processed for purposes of fighting the Corona-Virus must be informed under Article 13 GDPR or Article 14 GDPR once their data has been obtained.
  • Purpose limitation: Personal data collected for specific purposes, like preventing/slowing the further spreading of the Corona-Virus within a company, monitoring the citizens' abidance with governmental measures, medial research or tracking of interactions with infected persons shall only be processed for these purposes. The purpose must be in line with the legal basis chosen by the controller or defined by national legislation.
  • Data minimisation: Only personal data that is truly necessary for these purposes may be collected and processed. It is not possible to process data that is not crucially necessary to fulfill the choose purpose.
  • Accuracy: Personal data must be accurate and, where necessary, kept up to date. Especially "big data" and "quick and dirty" approaches that may be though of at times of crisis, may conflict with this principle. In cases where personal consequences may rely on data (e.g. limitation of movement, access to health care or saving people from infections) the accuracy of personal data is of utmost importance.
  • Storage limitation: Once the purposes for processing are fulfilled, the data must be deleted or anonymised. When processing data about individual persons, the currently established timelines (e.g. the now common 14 days of quarantine) also form the basis for any storage limitation. Data may be anonymized, to be further used for statistics or research purposes.
  • Integrity and confidentiality: Appropriate security of the personal data, including protection against unauthorised or unlawful processing and accidental loss, destruction or damage must be ensured with the implementation of technical or organisational measures (Article 32 GDPR). Taking security measures seriously is especially crucial when processing operations are stated under short timelines and pressure and the wider populations should trust these measures.

Legal Basis under Article 6 GDPR

Insofar data processing concerns only personal data, that does not qualify as special categories of personal data (such as health data under Article 9(1) GDPR (see below)), processing activities can realistically be based on:

  • Article 6(1)(d) GDPR, if processing is necessary to protect vital interests of the data subject or of another natural person; since the Corona-Virus is considered to be highly virulent, data can be processed in order to protect both infected people and others, to prevent them from being infected.
  • Article 6(1)(e) GDPR, if processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller; this legal basis can be invoked by public authorities pursuing the mentioned purpose. Such a measure may be based on a national implementing law (Article 6(2) GDPR).
  • Article 6(1)(f) GDPR, legitimate interests pursued by the controller or by a third party; this legal basis may also be invoked by private controllers, since there will not always be vital interest of the data subject or of other persons at stake, but processing is only necessary for "less severe" reasons, e.g. if certain goods and services are limited due to difficulties of supply and it must be ensured that these goods and services are equally distributed among customers. Article 6(1)(f) GDPR does not apply to processing carried out by public authorities in the performance of their tasks; these authorities have to rely on Article 6(1)(e) GDPR.

Legal Basis under Article 9 GDPR

Article 9(1) GDPR lines out the conditions under which special categories of personal data may be processed. With regards to the Corona-Virus this mostly concerns health data, genetic data and biometric data for the purpose of uniquely identifying a natural person (e.g. at airports or state borders).

Article 9(2)(i) GDPR deals with scenarios such as the current Corona-Virus, which qualifies as a "serius cross-border threat to health":

"[...] processing is necessary for reasons of public interest in the area of public health, such as protecting against serious cross-border threats to health or ensuring high standards of quality and safety of health care and of medicinal products or medical devices, on the basis of Union or Member State law which provides for suitable and specific measures to safeguard the rights and freedoms of the data subject, in particular professional secrecy."

Furthermore, the recent Latvian DPA (the DVI)'s guidelines highlight that Article 9(2)(j) GDPR could be a legal basis for scientific research purporses or statistical purposes.

Lastly, Recital 46 of the GDPR specifically mentions epidemic scenarios:

"The processing of personal data should also be regarded to be lawful where it is necessary to protect an interest which is essential for the life of the data subject or that of another natural person. Processing of personal data based on the vital interest of another natural person should in principle take place only where the processing cannot be manifestly based on another legal basis. Some types of processing may serve both important grounds of public interest and the vital interests of the data subject as for instance when processing is necessary for humanitarian purposes, including for monitoring epidemics and their spread or in situations of humanitarian emergencies, in particular in situations of natural and man-made disasters."

Other elements of GDPR

Obviously, all other elements of GDPR also apply to processing of personal data, when fighting the Corona-Virus. Notably the rights of the data subject (Article 12 to 23 GDPR) including the rights to information ("Privacy Policy"), access, rectification and alike are highly relevant to any Corona related processing.

The concept of "privacy by design" Article 25 GDPR seems crucial in designing larger scale systems. As many processing operations will relate to sensitive health data, special precautions from a data security standpoint Article 32 GDPR should be observed.

In addition, data protection impact assessments under Article 35 GDPR will be mandatory regarding a lot of these processing activities, especially in cases of large scale processing of special categories of personal data (Article 35(3)(b) GDPR) or the systematic large scale monitoring of publicly accessible areas (Article 35(3)(c) GDPR).

DPA Guidelines

In the context of the Corona Virus, the EU/EEA data protection authorities released guidelines on the processing of personal data and also on the continuity of their tasks in times of the Corona-Virus:

On 19 March 2020, the EDPB adopted a full statement here, explaining the lawfulness of processing, processing in the employment context as well as processing of location data.

Envisaged or conducted processing activities regarding COVID-19 per EU member state

The following table shows data processing activities that have been envisaged by EU member states or private companies or that already have been implemented:

EU member state Processing Activities Status Comments Source
Austria Telecommunication provider A1 transmits - allegedly anonymised - location data of mobile phone users to the Austrian government Confirmed The purpose of this processing activity is to track the decrease of the presence of citizens in public areas.

According to A1, the location data are being anonymised by assigning randomly generated numbers to each mobile phone user. These numbers are changed every 24 hours. A1 also stated on its home page, that movement of persons is only analysed and visualised in "groups of 20 or more people", since the technology has originally been developed to track streams of tourists in the proximity of tourist attractions.

Concerns have been voiced that there is no legal basis for the processing of historical location data. In addition, it is unclear whether the assignment of random temporary numbers qualifies as anonymisation or is a measure of mere pseudonymisation. If the latter is true, the GDPR fully applies.

The Austrian Red Cross (Österreichisches Rotes Kreuz) has announced the deployment of a mobile phone app, which allows users to track their "digital handshake" - allegedly using only anonymised data. If an app-user is confirmed to be infected with the Corona-Virus, other app-users that have been in contact with the afflicted app-user are informed via the app. Officially announced Appartently, each app-user is assigend a (random?) ID and feeds the app with the IDs of persons he or she has been in contact with, which is done via an ultrasound audio beacon between the devices. The app-user is notified later, if one of his recent contacts has been infected, without disclosing the ID of the infected person. These IDs are retained for a period of only 48 hours.

However, this set-up still gives rise to doubts that the data are truly anonymised for all parties involved: In cases where the app-user has only been in contact with a small amount of people, it might be very easy for him or her to identify the infected person by taking notes on whom he/she has entered into the app. As the data are stored for only 48 hours it is also possible for the app-users to simply remember their encounters. Thus, the data might me anonymised for the Red Cross, but not for the app-users themselves (the app is said to collect no data of the mobile phone user).

Bulgaria On 13th March 2020 the Bulgarian Parliament adopted Law on Measures and Actions during the the state of emergency, effective as of 23rd March 2020, published with State Gazette No 28/24.03.2020. One of the measures adopted requires the establishment of checkpoints at the regional cities so that law enforcement authorities can check people (Article 9 and 10). Bulgarian citizens are allowed to travel between regional cities only when there is an urgent need for that - going to work, health reasons or returning to their permanent or current address. Bulgarian citizens can pass these checkpoints only with filled declaration. Implemented In this regard, the Bulgarian DPA issued an opinion regarding the legality of the the processing of personal data by the Ministry of Interior by collecting declarations from citizens passing through the checkpoint. Text is available here
With para. 41 of the Law on Measure and Actions during the state of emergency, the Electronic Communications Act is amended giving the power to the law enforcement authorities to track citizens' mobile phone and identify their location only if the citizen is put under mandatory quarantine and does not follow the instructions given or refuse to follow them. The telecommunication companies shall provide the law enforcement authorities with the location data upon their request, i.e. no approval by the court is necessary. Implemented Example Example

France Processing carried out by open e-communication network operators. The French Parliament ('l'Assemblée nationale') and the Senate ('le sénat') adopted the Law on the first reading. The Law is not yet in force.

In the first reading version amended by the Senate, the operators were allowed to take any measures necessary to ensure that the priority needs of the population continue to be met in such crisis situation. The amendment has been deleted. See the enacting progess here.

The provisory version adopted by the Parliaments does not contain any provision regarding any processing of personal data here.
Germany The telecommunication provider Telecom transferred location data of mobile phone users to the public health institute ("Robert Koch Institut"). Confirmed. The Federal Commissioner for Data Protection and Freedom of Information stated on Twitter that the transfer is justifiable in the chosen form. According to his statement, the transferred information do not allow the identification of individuals.

Telecom conducts a data anonymization platform. Individuals have the option to opt-out.
Federal Minister of Health Jens Spahn decided to not use phone data in the fight against covid. Plans for a new respective law are postponed to after easter. Legislative proposal is confirmed. Cell phone tracking was part of a legislative proposal designed to give the federal government more competencies in the fight against epidemics. The Federal Commissioner for Data Protection and Freedom of Information published a statement on the legislative proposal. He raised doubts regarding the necessity and proportionality.
Greece Personal data (name, surname, home address, reason for going out, work address when work is the reason for going out and telephone number) is included in an SMS which is sent to the General Secretariat of Civil Protection once an individual leaves their places (time). This is one of the two options an individual may have; the second one is filling out and carrying a hard-copy form with the mentioned data plus some more. This form has to be only demonstrated to the police or other enforcement authorities and is not stored. Implemented The General Secretariat of Civil Protection published a Privacy Policy, according to which the data collected via the mentioned SMS will be processed only by the Secretariat and only for the purpose of supervising the compliance of individuals with the imposed measures against the spread of Corona-Virus. According to the privacy policy, once the data subjects receive a confirmation sms, the mentioned data is either deleted or anonymised and kept for statistical purposes only. The privacy policy mentions that all necessary safeguards have been implemented and all data subjects' rights according to the GDPR shall be respected.

However, the privacy policy is very vague and contradictory.

Norway Bergen municipality implemented a location based alert and information system. Confirmed The implemented system is used for "geo-fencing" the municipality, so that people arriving within the perimeter are notified of restrictions to avoid infection. In addition, the system can send an alert to all SIM-cards in a geographic area to break up crowds. Apparently, only an approximation of the number of people in a given area and of a certain size is provided, as well as different nationalities connected to SIM-cards.

According to the municipality, the data is received aggregated from the telecommunication providers.

The Norwegian Institute of Public Health is working on an app to track people's movement Exact details unclear Working together with the state owned research and development company Simula Research Laboratory, the Norwegian Institute of Public Health is currently working on an app to track peoples movements in order to see who has been close to someone infected. The national public broadcaster NRK reported on source code that contained examples on how to discover people who had been within 50 meters of each other for at least a minute.

The Norwegian Institute of Public health confirmed that they were considering an app for tracking, but that no decision had been taken yet. According to the Institute of Public Health's newly published risk assessment of the virus, they are only a few days away from launching an app.
Poland On 7 March 2020, the Minister of Health adopted a Regulation on the list of diseases giving rise to obligatory quarantine or epidemiological surveillance and the period of obligatory quarantine or epidemiological surveillance (Dz. U., 2020, item 376). Since the entry into force of this Regulation, persons infected or suspected of being infected with coronavirus shall be administered to surveillance measures if the health services so decide. Confirmed The Polish police conducts regular checks of the persons who are subject of the 14-day quarantine obligation. Officers call the person's phone and ask them to look out the window or have a short conversation over the intercom or videophone.

An alternative method to monitor persons under the quarantine were adopted by the Polish Ministry of Digital Affairs who developped a mobile app "Home Quarantine" (Aplikacja Kwarantanna domowa). The mobile app allows to confirm the location of a person covered by the quarantine restrictions and to conduct basic health assessment. In addition, the app allows for a quick access to the necessary quarantine information, and to contact the local social welfare centres, which can provide medicine or food in justified situations. The app has access to the GPS and camera on the user's mobile phone. The use of the application is voluntary.
