Abstract

See full text

A medical professional registers himself with the trust centre (TC) or trusted registry (TR) acting on behalf of and/or operated by the mobile communication service provider. According to an embodiment of the present invention, the trust centre or trusted registry generates a pair of keys (“private key, public key”) and associates the private key with the mobile-phone identity (IMEI, SIM-chip-number or phone number) in a secret table stored at the TC or TR. The TC or TR also associates the public key with the medical author's name (plus office address) as an entry into a directory.
