If you are concerned for your property because of thefts, burglary or vandalism, you have probably already resorted to the use of CCTV or at least you have considered it. From a technical perspective, the placement of video devices is becoming easier and easier with the development of technology. However, the legal risks arising from the use of CCTV do not diminish – exactly the opposite. What requirements should you comply with when using video devices? What are the restrictions on processing of personal data by video devices? What obligations does Regulation 2016/679 (GDPR) impose on you as personal data controller? The European Data Protection Board (EDPB/The Board) gives some practical guidelines, the most important of which are summarized below:
Lawfulness of Processing
If none of the legal
grounds listed in Article 6 GDPR applies, the processing of personal data would
not be lawful. The most commonly used legal basis in the context of video
surveillance is the legitimate interest of the controller (for instance,
protection against burglary). It is necessary:
- Imminent risk or dangerous situation to
exist and the controller to be able to prove its
existence – for example by means of statistics of the crimes rates in the area;
- no other means for protecting the
legitimate interest to be available, except the installation of CCTV;
- the reasonable expectations of the data
subjects to be considered – e.g., it is inconceivable CCTV to be used in
restrooms, bathrooms, etc.;
- the surveillance to be strictly limited to
the area of the premises that is being protected (the area may be expanded only
if this is necessary for achieving effectiveness of the surveillance).
Disclosure of Video Footage to Third Parties
Any disclosure of
personal data is a separate kind of processing for which a separate legal basis
must be present. Such basis may be legal obligation of the controller to disclose
the data to law enforcement authorities (e.g. investigation).
Processing of Special Categories of Data
If the processing of
special categories of data is necessary, then at least one of the additional grounds
allowing the processing must be present (Art. 9, § 2 GDPR). If the purpose of
the processing is to protect the vital interests of the subject and he or she
is physically or legally incapable of giving consent, this would justify the
processing of such data (Article 9 § 2 (c)). Such an example is the monitoring
of a patient, who was brought to the hospital unconscious. If the surveillance began
when he was unable to consent, it would not be contrary to GDPR requirements. The
Board also comments on the exception in Art. 9 regarding data which is manifestly
made public by the data subject. According to the Board, the mere fact of
entering the range of a camera does not permit the data controller to process
special categories of data on the grounds that the data subject manifestly made
them public.
Rights of the Data Subject
It is important to note
that data subjects enjoy all the rights provided in the GDPR – the right to
information and access to the data being processed, the right to be
“forgotten”, etc. However, some of the data subjects’ rights require
further clarification in the context of CCTV:
Right to Access
If the controller resorts
only to real-time monitoring and no data is stored, then in case of a request
by a data subject it is sufficient to confirm that no personal data is being
processed any longer.
The Board also draws
attention to cases where the data subject could not be provided with access to
the processed data relating to him:
•
If the disclosure of the data would adversely affect the rights of third
parties (for example, providing video footage to one data subject could
adversely affect the rights and freedoms of others where other subjects can be
identified. In such cases, the Board advises not to restrict the right to
access to the data subject, and instead use photo processing tools that hide
the identity of third parties).
•
If the controller is unable to identify the subject – for example, if plenty of
people pass through the monitored area;
•
If the request is manifestly unfounded or excessive (due to repetitiveness, for
example);
Right to Erasure (Right to be Forgotten)
The personal data
collected during processing must be deleted if they are no longer needed for
the purposes for which they were processed. Furthermore, the personal data must
be erased:
•
Upon request of the data subject. If the data was provided to third parties,
the latter must also be informed of the request made;
•
Depending on the legal basis for the processing, personal data should be
erased:
- when the data subject withdraws his or her
consent for processing;
- when the interests of the subject override
the legitimate interest of the administrator;
- when the data subject objects to the
processing of the data for direct marketing purposes.
In addition to the
obligation of the controller to erase the data upon request, the principle of
minimizing the data must also be kept in mind – the data processed should be
relevant and limited to what is necessary for the purposes for which it is
processed.
Right to Object
The data subject has the
right to object to the processing of the data (before entering, monitoring, or
leaving the surveillance zone). The controller must demonstrate that his or her
legitimate interest or the protected public interest outweighs the subject’s
rights and interests (for example, processing is necessary for the conduct of
an internal investigation).
Transparency and Information Obligations in the Context of CCTV:
Some of the most useful
guidelines given by the Board are related to the way the data subjects must be
informed. A good practice that meets the standards of the Regulation is the
so-called layered approach for presenting the information:
First layer: A warning sign that informs in a clear and unambiguous manner about the video surveillance. There is no need to indicate the exact location of the cameras. First layer – content:
- Identity of the controller, including representatives and contacts of Data Protection Officer, if such is appointed;
- Purposes and legal grounds for processing;
- Information on the greatest impacts of the processing;
- Any information that could surprise the data subject.
The second layer of information includes further details regarding the CCTV. It may be presented in the form of information leaflets placed in an easily accessible and visible place.
Storage Period and Technical Requirements
The longer the storage
period (especially over 72 hours), the more evidence for the necessity of
storage must be provided. Usually, the storage is justified by the potential
need for the data to be used as evidence. However, a period of 24 hours is
usually sufficient for this purpose.
When selecting technical
means of monitoring, the controller must comply with all the principles
concerning the data processing laid down in the Regulation. Appropriate
technical and physical protection of the components of the CCTV system must be implemented.
The access to the system and the recordings must be limited only to subjects authorized
by the controller.
Impact Assessment
In the last part of the
Guidelines, the Board recalls that if processing is carried out through
systematic monitoring of publicly accessible areas on a large scale or when
special categories of data are processed, the Regulation requires that a data
protection impact assessment (DPIA) be carried out. The guidеlines on DPIA and determining whether
processing is “likely to result in a high risk” for the purposes of
Regulation 2016/679 are available here.
