The funsion type user authentication method comprises the steps of: receiving a resident registration number, a mobile number, and a customer name for self authentication of a customer from the authentication request server; extracting the birth date and sex indicator of the customer from the resident registration number of the customer; providing the birth date, the sex indicator, the customer name, and the mobile number of the customer to the communication company server; receiving connecting information (CI), which is generated by using a possession authentication value for the mobile number assigned by the communication company server, and the resident registration number stored in the communication company server; comparing the CI, which is acknowledged by an Internet personal identification number (IPIN) server, with the received CI based on the resident registration number of the customer to authenticate whether they match; combining an authentication result value of the CI with the possession authentication value and generating an self authentication result; and providing the generated self authentication result of the customer to the authentication request server. Hear, the authentication request server can include a financial company server, provided in a financial company, which requests the self authentication of the customer based on the resident registration number of the customer.
