Abstract:
[Problem] It is desirable that a technology be provided whereby, even if anonymous information has been leaked, it would be difficult to identify which user the leaked anonymous information is associated with. [Solution] Provided is a server device, comprising: a risk value acquisition unit which acquires a risk value in a situation in which a user's anonymous information has been leaked; and a process execution unit which associates, with the anonymous information, an anonymous ID for identifying the anonymous information. If the risk value exceeds a prescribed threshold value, the process execution unit executes: a process of switching the anonymous ID which is associated with the anonymous information; and/or a process of changing an anonymous ID which is associated with each of a plurality of information segments that are obtained by segmenting the anonymous information.
