Abstract
A package identifier generating unit generates, for each unique combination of information on specific items included in a package, a package identifier identifying the combination. A first table registering unit extracts information on the specific items from the obtained package, and registers the information on the specific items, a user identifier identifying a user of a program reproducing apparatus being a transfer source of the package, and the generated package identifier in correspondence with each other, in a first table. A second table registering unit extracts a correspondence relation between the user identifier and the package identifier from the first table, and registers the package identifier corresponding to the user identifier, as a program view history for each user, in a second table. A determining unit determines the package identifier being a difference between program view histories similar to each other registered in the second table.
