| 摘要 |
The invention relates to a system for authenticating electronic prescriptions, the system comprising an acquisition unit for acquiring an electronic prescription for authentication, the electronic prescription comprising a transaction number, a first pseudonym, and a signature of a first participant using a transaction pseudonym, the first pseudonym indicating the first participant's registration at a first privacy officer; a generation unit for generating the transaction pseudonym based on the first pseudonym, the transaction number and a registration key corresponding to the first pseudonym and being shared between the first participant and a second privacy officer; and a validation unit for verifying the first participant's registration at the second privacy officer and the authenticity of the signature based on the registration key and the transaction pseudonym. As the transaction pseudonym depends on registrations at two privacy officers and a transaction number for a real-time prescription, the participant's privacy can be well protected from each privacy officer.
