"We want to create a digital single European market. That means we need to have legal situations that are as similar as possible in all European countries," Merkel said in her weekly video podcast, Reuters reported.
A key issue is determining who owns the data and the related copyright issues, Merkel said, adding: "We're still discussing that."
She said that in the automobile sector, for example, it was important to clarify whether data belonged to carmakers or software manufacturers because it was possible to develop new products with the data about clients.
"We need to very quickly and uniformly implement legislation in Europe regarding copyright laws and the ownership of data," she said.
