WASHINGTON -- Apple Inc., said it received 4,000 to 5,000 requests for customer data from U.S. officials during the six months ending in May, as it became the latest high-tech company to provide some details on its involvement in the National Security Agency's Internet surveillance program.
The requests involved 9,000 to 10,000 customer accounts or devices, the company said in a statement on its website. Not all the requests involved the NSA's controversial Prism program, which the company said it did not know about until revelations in the news media on June 6.
The data requests came from federal, state and local authorities and involved national security matters and criminal investigations, Apple said.
"The most common form of request comes from police investigating robberies and other crimes, searching for missing children, trying to locate a patient with Alzheimer’s disease, or hoping to prevent a suicide," the statement said.
Apple said some types of data are never provided, including FaceTime conversations and requests made through its Siri voice assistant.
On Friday, Facebook said it received 9,000 to 10,000 government data requests in the second half of 2012, involving 18,000 to 19,000 accounts. The company said it complied with 79% of the requests.
