Abstract: (a) Step of a portable information processing device (65a) reading an image code by, editing first level personal information stored in the portable information processing device (65a) and information incorporated in the image code, and directly accessing a business server (64a) based on the edited information; and a license registration server (28) then receiving second level personal information of a higher security level than the first level personal information stored in the portable information processing device (64a) and network information of an access destination of the business server (64a); and (b) step of the license registration server (28) determining whether the portable information processing device (65a) is of a registered user; and (c) step of the license registration server (28) determining whether the business server (64a) has a registered license; and (d) step of the license registration check server (28) authorizing processing for the portable information processing device (65a) to transm

Abstract: An information-processing server (30) (a) receives an action request with first level private information from a first terminal (20); (b) authenticates the first terminal (20) based on the first level private information; (c) issues authentication information to the first terminal (20); (d) receives from the first terminal (20) second level private information of a higher security level than the first level private information as well as the authentication information; and (e) transmits the second level private information for an action requested, to a second terminal (51) based on the authentication information, in a system including the first terminal (20), the second terminal (51), and the information-processing server (30) mediating between the first terminal (20) and the second terminal (51).
