Patent ID: 7654463

Claim:
An electronic document management system comprising: an acquisition unit, a medium comprising a document image, and a plurality of code images two-dimensionally arranged, each of the code images comprising position information and medium identification information uniquely identifying the medium as a particular medium type and a specific instance of the medium type, wherein the medium identification information includes associated attribute information and the electronic document management system is configured to allow a user to dynamically retrieve medium identification information of associated medium instances by forming associations between medium instances that share a common attribute from the database, where the attribute information relates to specific attributes for a person and can identify the attributes related to the person, and where the attribute information can be designated by the user when storing each of the medium instances, and the acquisition unit acquires a code image corresponding to an operation position on the medium in conjunction with a user's operation with respect to the medium, wherein the acquisition unit is capable of reconstructing the medium identification information from fragmentary information included in a reading region; a specifying unit that specifies the medium identification information included in the code image acquired by the acquisition unit; an application execution unit that executes an application in response to the user's operation, the execution occurring at nearly the same time as the user's operation; and a database that stores personal information associated with the medium identification information specified by the specifying unit.
