Apple on Wednesday denied claims that it had worked with the government to share millions of device identification numbers, a day after the hacking group known as AntiSec claimed to have obtained numbers from an F.B.I. laptop.
In a statement, Apple said it had not worked with the Federal Bureau of Investigation or any other agency to release the numbers, called unique device identifiers or U.D.I.D. numbers.
"The F.B.I. has not requested this information from Apple, nor have we provided it to the F.B.I. or any organization," said Natalie Kerris, an Apple spokeswoman. "Additionally, with iOS 6, we introduced a new set of A.P.I.'s meant to replace the use of the U.D.I.D. and will soon be banning the use of U.D.I.D."
