[Problems to be Solved by the Invention] It is an object of the present invention to provide a data management apparatus capable of efficiently managing various data that is transmitted and received via a network, by automatically and adequately generating an ID with which the identity of pieces of data can be verified and associating the ID with the pieces of data, even if specifying information such as a marking assigned to the piece of data is modified by a completely independent server. [Means for Solving the Problems] A data management apparatus includes: an identification information storing unit that stores a plurality of pieces of identification information that are associated with a plurality of groups, respectively; a specifying information obtaining unit that obtains a piece of specifying information assigned to a piece of data; a collating unit that collates the piece of specifying information and each of the plurality of pieces of identification information, and judges whether the piece of specifying information matches any one of the plurality of pieces of identification information; and an assigning unit that assigns the piece of data to a group associated with the piece of identification information judged by the collating unit to be matched, from among the plurality of groups. |
