The Department of Defense (DOD) is seeking ways to biometrically identifying people when they sign in to use computers without interrupting their normal activity flow.

The Defense Advanced Research Projects Agency's Active Authentication Program aims to develop software to identify "the individual at the keyboard … through the activities the user normally performs," according to an agency posting on FedBizOpps.gov announcing an Industry Day event about the program next week.

"The Active Authentication program changes the current paradigm by removing the secret that a human holds, the password, and focuses on the secret that the human specifically is," according to DARPA.

Biometric authentication for computers already exists, but usually it is done through an extra step a use must take when logging in, such as pressing a finger to a pad that can scan and identify someone through their fingerprint.

Iris scanning--in which a person is identified by a machine that captures an image of his or her iris--also is another popular biometric-authentication method, but normally for larger form-factor machines, such as airport security scanners.

DARPA, however, wants to skip any extra steps and locate biometric factors to identify someone while they're working naturally at the keyboard, according to the agency. The initial goal for the program is to identify someone working at a desktop in a typical DOD office environment.

On the Industry Day, DARPA plans to discuss its ideas for new approaches to biometrics and identify potential participants in the program.

Given the vulnerabilities of traditional password authentication systems, the federal government has been working on biometric options for identifying users of its systems and facilities to more firmly secure access to them.

To that end, the feds are developing biometric ID cards that include options for both fingerprint and iris scans for all federal employees and contractors when entering facilities or using computer systems. The move is mandated by Homeland Security Presidential Directive 12, which is aimed at increasing security and efficiency, reducing identity fraud, cutting costs, and protecting personal privacy.

CVE-2014-8361
Published: 2015-05-01
The miniigd SOAP service in Realtek SDK allows remote attackers to execute arbitrary code via a crafted NewInternalClient request.

CVE-2015-0237
Published: 2015-05-01
Red Hat Enterprise Virtualization (RHEV) Manager before 3.5.1 ignores the permission to deny snapshot creation during live storage migration between domains, which allows remote authenticated users to cause a denial of service (prevent host start) by creating a long snapshot chain.

CVE-2015-0257
Published: 2015-05-01
Red Hat Enterprise Virtualization (RHEV) Manager before 3.5.1 uses weak permissions on the directories shared by the ovirt-engine-dwhd service and a plugin during service startup, which allows local users to obtain sensitive information by reading files in the directory.
