Admonition for revealing a list of people quarantined in Poland
The President of the Personal Data Protection Office in Poland (UODO) imposed an admonition on a company dealing with waste management liable for a data breach and ordered to notify the concerned data subjects. The admonition is based on a violation of personal data pertaining to data subjects under medical quarantine. The city name, street name, building/flat number and the fact of remaining under quarantine of the affected data subjects have been provided by the company to unauthorized recipients. The various recipients were required to verify whether, in a given period, waste was to be collected from places determined in the above-mentioned list.
The incident already happened in April 2020. Back then, a list of data subjects was made public, containing information on who had been quarantined by the administrative decision of the District Sanitary-Epidemiological Station (PPIS) in Gniezno as well as information on quarantined data subjects in connection with crossing the country border and on data subjects undergoing home isolation due to a confirmed SARS-CoV-2 infection. After becoming aware of the revelation, the Director of PPIS notified the relevant authorities – the District Prosecutor’s Office and the President of UODO – about the incident.
PPIS informed them that it had carried out explanatory activities showing that the source of disclosure of these data was not PPIS. These data were provided to the District Police Headquarters, the Head of the Polish Post Office, Social Welfare Centres and the Headquarters of the State Fire Service. Considering the fact that these data had been processed by various parties involved, it was necessary to establish in which of them the breach may have occurred.
UODO took steps to clarify the situation. In the course of the proceedings, it requested information from a company dealing with waste management being one of the recipients of the personal data. The company, acting as the data controller, had to explain whether, when establishing the procedures related to the processing of personal data, it had carried out an assessment of the impact of the envisaged processing operations on the protection of personal data according to Art. 35 GDPR. The assessment persists in an analysis of the distribution method in electronic and paper form in terms of risks related to the loss of confidentiality. Furthermore, the data controller had to inform UODO about the result of this analysis.
The data controller stated that it had conducted an analysis considering the circumstances related to non-compliance with the procedures in force by data processors and circumstances related to theft or removal of data. Moreover, the data controller expressed the view that the list, received from the District Police Headquarters, only included administrative (police) addresses and did not contain names, surnames and other data allowing the identification of a natural person. Thus, the GDPR would not apply, because the data has to be seen as anonymized. However, from the list also emerged the fact that residents of these buildings/flats were placed in quarantine, which made it possible to identify them. It came out that the confidentiality of the processed data had been violated in the course of the performance of employee duties of the data processor, who had left the printed list on the desk without proper supervision. During this time, another employee had recorded the list in the form of a photo and had shared it with another person.
Following the review of the entirety of the collected material in this case, UODO considered that the information regarding the city name, street name, building/flat number and placing a data subject in medical quarantine, constitute personal data within the meaning of Art. 4 (1) GDPR, while the last comprises a special category of personal data concerning health according to Art. 9 (1) GDPR. Based on the above, it is possible to identify the data subjects, and therefore the data controller is bound to the obligations arising from the GDPR.
In the opinion of UODO, the protective measures indicated in the risk analysis are general formulations, which do not refer to specific activities undertaken by authorized employees. The measures are insufficient and inadequate to the risks of processing special categories of data. In addition, the data controller should have considered factors, such as recklessness and carelessness of employees and a lack of due diligence.
According to Art. 33 (1) GDPR, the data controller shall without undue delay and, where feasible, not later than 72 hours after having become aware of the data breach, notify it to the competent supervisory authority. Moreover, in a situation of high risk to the rights and freedoms of the data subjects, resulting from the data breach (which undoubtedly arose from the disclosure), the data controller is obliged to inform the data subject without undue delay in accordance with Art. 34 (1) GDPR. Despite this, the company did not report the infringement, neither to the President of UODO nor to the concerned data subjects.
