Abstract
An information management apparatus receives position data from each terminal device. The position data contains position measurement data showing its positions at multiple clock times and its user identification data. The apparatus creates action history for every user based on the position data, and abstracts the position data in the action history. The apparatus includes an abstracting section and a testing section. The abstracting section abstracts arbitrary position data in the action history of a certain user. The testing section extracts another action history of another user. The other action history includes position data of the other user which shows a position same as or included in a position of the abstracted position data of the certain user, but excludes position data of the other user which shows positions same as remaining position of the certain user. The testing section outputs the abstracted position data as anonymity data.
