The Pentagon has a big plan to solve identity verification in two years

The technology, which will be embedded in smartphones’ hardware, will analyze a variety of identifiers that are unique to an individual, such as the hand pressure and wrist tension when the person holds a smartphone and the person’s peculiar gait while walking, said Steve Wallace, technical director at the Defense Information Systems Agency.

Organizations that use the tool can combine those identifiers to give the phone holder a “risk score,” Wallace said. If the risk score is low enough, the organization can presume the person is who she says she is and grant her access to sensitive files on the phone or on a connected computer or grant her access to a secure facility. If the score’s too high, she’ll be locked out.
