(Reuters) -British officials held private talks with their U.S. counterparts to resolve concerns that UK is trying to force Apple ( AAPL ) to build a backdoor into Americans' encrypted data, Bloomberg News reported on Thursday, citing people familiar with the matter.

The reported talks are being held after the iPhone maker removed its most-advanced security encryption for cloud data, called Advanced Data Protection, in Britain last month, in an unprecedented response to government demands for access to user data.

That means Apple ( AAPL ) can access iCloud backups in certain cases that it otherwise could not, such as copies of iMessages and hand it over to authorities if legally compelled. With end-to-end encryption enabled, even Apple ( AAPL ) could not access the data.

Apple ( AAPL ) did not immediately respond to a Reuters request for comment.
