Abstract
The present invention provides a distributed anonymization device capable of executing a distributed anonymization process without the risk of leaking data of users to other parties. This distributed anonymization device is provided with: a storing means for storing a user identifier and personal information in association with one another; a setting means for setting, as a dummy identifier, the identifier that does not correspond to the user identifier from among all of the externally-notified identifiers; a separating means for separating all the identifiers including the dummy identifier into groups; a transmitting means for transmitting to another device, the separation information indicating the content of the identifiers in each group; and a determining means for determining, each of groups, whether the proportion of identifiers in the abovementioned distributed anonymization device and the other device satisfy a predetermined anonymity index.
