System for processing information, device for processing information, and program

摘要

An information processing system including: first and second information processing devices in communication through a network. The first device has a license information-sending unit that sends license information containing utilizing-time limit information for utilizing a content in response to a request from the second device. The second device has: a license information-receiving unit that receives the license information sent by the license information-sending unit; a time information acquisition unit that acquires time information through the network; an internal clock-setting unit that refers to the time information acquired by the time information acquisition unit to set time information of a built-in internal clock; and a utilization-controlling unit that controls utilization of the content in association with the license information received by the license information-receiving unit based on the time information of the internal clock set by the internal clock-setting unit or a counter working independently of the internal clock.
