Diversinet Expands Mobile Security Intellectual Property Portfolio with U.S. and Canadian Patents

Patents Support BYOD, Enable Greater Security and Convenience for Healthcare, Banking, Government and Various Other Enterprise Uses

TORONTO, Feb. 6, 2013 /PRNewswire/ - Diversinet Corp. (TSX Venture: DIV, OTCQB: DVNTF), a leader in secure mobile health that "Powers Care Coordination through Mobility," has been issued two key mobile security patents by the United States Patent and Trademark Office and the Canadian Intellectual Property Office.

U.S. patent # 8,341,712, "Method and System for Authenticating a User of a Mobile Device," provides convenient new options for enabling multi-factor authentication. This technology enables patients to use their phones as part of multi-factor authentication for remote access to personal health information. This is in line with U.S. government standards proposed to take effect in 2015 with Stage 3 of the HITECH Act's meaningful use incentive program.

Canadian patent # 2,665,961, "Method and System for Delivering a Command to a Mobile Device," enables solutions that help enterprises ensure security and productivity amid the bring-your-own-device (BYOD) trend, including the emerging mobile wallet, or container, architecture. This technology enables healthcare vendors to allow hospitals to remotely wipe lost and stolen smartphones and tablets. It also enables productivity-building capabilities, such as securely delivering a command to a mobile device that launches an application. Diversinet has submitted a similar U.S. patent application.

The patents expand Diversinet's intellectual property portfolio to 22 granted and 26 pending patents. The portfolio provides the company, its customers and its licensees competitive advantages in markets such as healthcare, banking, government and general enterprise.

"Diversinet's 48 granted or pending patents are a key corporate asset, as they enable organizations to create industry-first security and productivity solutions that address the rapidly-changing mobile needs of enterprises and government agencies."
