TORONTO, Canada, April 12, 2006 - Diversinet Corp. (OTCBB: DVNTF), a leading provider of mobile-enabled personal authentication and security solutions, today announced a partnership agreement with Infosec Co., Ltd., a leading Korean global e-security integrator and an affiliate as well as a security partner of the SK Group ("SK Infosec"), to distribute Diversinet's OATH-compliant MobiSecure software tokens and MobiSecure Authentication Service Center (MASC) provisioning service in Korea.
