Abstract: A current measurement device (1 to 3) includes a first sensor (SE1) configured to detect a direct current magnetic field and a low-frequency alternating current magnetic field generated by a current (I) flowing through a measurement target conductor (MC), a hollow magnetic shielding member (12) that includes a cutout portion (CP2) into which the measurement target conductor is inserted and in which the first sensor is accommodated, a fixing mechanism (13) configured to fix the measurement target conductor such that a distance between a center of the measurement target conductor inserted into the cutout portion of the magnetic shielding member and the first sensor is a predetermined reference distance (r), and a first calculator (21) configured to calculate a current flowing through the measurement target conductor based on a detection result of the first sensor.

Abstract: According to one embodiment, an information management server apparatus transmits processing result information that includes management register information including a child management ID when traceable duplication request information received from an information medium controller satisfy an access control policy and a permission policy. On the basis of the processing result information, the information medium controller outputs document print data that includes the child management ID tag and an electronic data body, and management register data including the management register information. When a paper document printed by the document print data is collected after being distributed, the information medium controller transmits a collection completion update request including the child management ID read from the paper document by an exclusive reader.

Abstract: According to one embodiment, even when the information media controlling apparatus which requests replication registration of electronic data and the information media controlling apparatus which acquires a child management file generated by replication registration are separate apparatuses, the information management server apparatus registers a child management ID of electronic data and a post office box ID of the acquisition destination of a child management file, in the post office box management table based on replication registration request information received from one information media controlling apparatus, and has the other information media controlling apparatus which is the acquisition destination acquire the child management file based on the post office box management table.

Abstract: In one embodiment of the present invention, the information management server apparatus includes an information management relation DB which stores the issued management ID and forming time and date information, user information, a medium type, a use limitation policy, and information management server information in a header portion of the copied management file in association with each other with respect to a management ID of a management file in management file copying request information. The electronic medium control apparatus requests an electronic copying of the management file. The management file is managed in the information management relation DB.
