Abstract: A method for syntagmatically managing and operating certification using an anonymity code is provided, which includes causing a quasi-public syntagmatic certification center to receive basic information including a terminal identification number when the terminal requests certification, causing the quasi-public syntagmatic certification center to detect whether there is an identity between a first resultant code and a preset corresponding anonymity code, causing the quasi-public syntagmatic certification center to determine whether to perform the certification with respect to the certification request depending on whether there is the identity between the first resultant code and the anonymity code, and causing the quasi-public syntagmatic certification center to send the certification result to the user terminal as a reply.
