When a member makes an access to the Internet, the personal information on the member (10) is protected. A personal information protective method is characterized in that a provider (20) issues an ID number to a member when a contract is made between them and manages the IDp related to the ID number and used to access a virtual shop (30) on the Internet and the personal information on the member (10), and the member (10) makes an access to the provider (20) using the ID number and an access to the virtual shop (30) using the IDp. Since the member (10) uses the ID that the provider (20) has when accessing the Internet, the personal information on the member (10) is protected. When the member (10) purchases data or a commodity at the virtual shop (30) of a website, the provider (20) sponsors the member (10) and guarantees the solvency of the payment, thereby realizing transaction safe for both the member (10) and the virtual shop (30).
