Original Abstract Submitted

A data management system includes a plurality of data management apparatuses, a certification authority group, and a time stamp authority group. In making an application for a proof of existence of invention information, the data management apparatus generates an invention hash, and transmits the invention hash to selected time stamp authorities of the time stamp authority group. Each of the time stamp authorities having received the invention hash generates a time stamp token. The data management apparatus acquires the time stamp token from each of the plurality of time stamp authorities to which the invention hash has been transmitted.
