Passwords for network security are out and faces are in at ParadigmHealth.

The Upper Saddle River, N.J., provider of care to seriously ill patients is adopting a Web-based authentication method that requires doctors, nurses and other users to remember images of nine faces to gain access to patient records through ParadigmHealth's Web portal.

"There's a huge advantage in this high-security face recognition" over easily shared and compromised passwords, says Tom Hagen, CEO of the healthcare company, which is using technology from PassFaces.

Healthcare providers, not often viewed as IT innovators, are becoming increasingly aggressive and creative about network security. Their efforts go hand in hand with regulatory requirements to safeguard patient data, and recognize that wireless and other technologies fit the mobile jobs of doctors and nurses.

Kettering Medical Center Network in Dayton, Ohio, has embraced wireless for staff and patients. It is adopting fingerprint biometrics to secure patient data.

The organization, which includes five major hospitals and numerous smaller facilities for a total of about 7,000 employees, last month began installing Cisco-based wireless LAN (WLAN) technology. The rollout will provide nurses and doctors with laptops on carts and mounted on walls that will require fingerprint biometrics for authentication for access to patient data.

The Sentillion single-sign-on software used for the project will let authorized staff bring up electronic records from where they're stored in Kettering's primary data center, says Bob Burritt, director of technology.

Once the network is up, Kettering will provide wireless hot spots for patients seeking Internet access.

Memorial Healthcare, a 1,000-employee hospital in Owosso, Mich., is a few steps ahead. It already has a segmented WLAN for use by patients and staff. The hospital also has put about 100 computers in hospital rooms for use by staff caring for patients. The latest round of innovation at Memorial came in January when nurses were given RFID-based badges to wear that automatically lock computers when they walk away from them.
