Information management device and information management method

Abstract

For a destination terminal not permitted to forward information, an information management apparatus (1A) sets first control information for permitting use of information within the terminal to the information. For a destination terminal permitted to forward the information, the information management apparatus (1A) sets second control information for permitting forwarding of the information to the information. The information management apparatus (1A) controls to permit local use of the information on the apparatus when the information set with the first control information is received from a source terminal, and controls to permit forwarding of the information when the information set with the second control information is received from a source terminal.

Description

technical field

[0001] The present invention relates to an information management device, an information management method, and an information management program. Background technique

[0002] Conventionally, there has been a prevailing method of promoting communication among members and improving convenience for members by forming a group of members having the same job, interest, etc., and providing information to the members in the group. For example, in such a group, an owner who owns information provides information by sending information from his own terminal to the terminals of other members.

[0003] In addition, as a group for sharing information, a temporary group for sharing information only for a certain period of time may be formed. There is known a method of transmitting one's own information to another's terminal via an introducing terminal in order to form such a temporary group. For example, if Figure 27 As shown in FIG. 1 , a commission request for introd...
