Luxembourg's national data protection commission (CNPD) said the majority of complaints related to the lack of respect for data confidentiality, or that data was not processed in the right manner.

In the presentation, held by the commission on Thursday, authorities said other complaints referred to the fact that the right of access to data had not been respected.

The commission's main objective is to supply information on data protection, as well as raising awareness and providing support. President Tine Larsen said they were encountering increasing cases of cyber crime and cyber harassment, as well as online fraud. "You have to be extremely careful and read all the terms and conditions before signing over your data," Larsen warned.

The commission is often contacted in cases where data protection is not respected. These topics are often of a different nature, said commissioner Thierry Lallemang.

"A classic case is video surveillance. But we also get complaints when the right of access is not respected, for example, if a person requests access to their data but the company does not respond. In these cases, we intervene to ensure the rights are respected.

Another example is the recent leak of sensitive data at the Luxembourg Regulatory Institute (ILR), concerning around 10,000 people.

"This was reported to us and we instructed them on how to proceed," Lallemang said. "It always depends on the risk of such a leak for people. And then we have to inform the people concerned about the incident."

Over the last few months, the CNPD has set up a secure channel for whistleblowers to get in touch. However, Thursday's presentation did not mention whether this venture had been successful, as the number of reports remained very small.
