U.S. digital advertising company Quantcast has became the latest technology firm to be investigated byIreland's Data Protection Commissioner.
Ireland hosts the European headquarters of a number of U.S. technology firms, making the Irish commissioner the lead regulator in the bloc under the EU's General Data Protection Regulation's (GDPR) "One Stop Shop" regime introduced last year.
The new rules give regulators the power to impose fines for violations of up to 4 percent of a company's global revenue or 20 million euros, whichever is higher.
The head of the Irish Data Protection Commissioner (DPC), Helen Dixon, told a U.S. Senate Committee on Wednesday that her office had 51 large-scale investigations under way, 17 of which relate to large technology platforms.
The probes spanned the services of Apple, Facebook , LinkedIn and Twitter, she said, adding that the first sets of investigations will conclude over the summer.
The regulator said in February that it had opened seven statutory inquiries alone into Facebook and three more into Facebook-owned Instagram and WhatsApp. It informed the social media giant of another probe last week.
San Francisco-based online measurement and advertising firm Quantcast, which established its European operations centre in Dublin in 2013, will have its transparency and retention practices examined as part of the probe, the DPC said.
"Since the application of the GDPR significant concerns have been raised by individuals and privacy advocates concerning the conduct of technology companies operating in the online advertising sector and their compliance with the GDPR," it said in a statement.
"The purpose of the inquiry is to establish whether the company's processing and aggregating of personal data for the purposes of profiling and utilising the profiles generated for targeted advertising is in compliance with the relevant provisions of the GDPR."
Quantcast said in a statement that it was reviewing the details of commissioner's inquiry and would cooperate fully with any investigation. (Reuters)
