BBC News reports hackers who breached US government networks stole far more fingerprint records than first thought, officials have said. In a statement, the White House said more than 5.6 million fingerprint records were stolen from the Office of Personnel Management (OPM). An initial investigation suggested only 1.1 million were lost. The OPM acts as the personnel office for the US government and keeps records on 21.5 million federal staff. The OPM played down the significance of the fingerprint theft saying that the ability to abuse the data was "currently limited." However, it acknowledged that the risk could rise as technology improved and fingerprints were increasingly used as a guarantee of identity.
