FILE TRANSMISSION SYSTEM, FILE TRANSMISSION MANAGEMENT SERVER, AND FILE INSPECTION METHOD

Japanese Patent JP2010283600

A

To inspect the identity of content data to be transmitted while alleviating a processing load at a receiving side.

A business broadcasting server 150 receives data for the inspection of a transmitting side including a transmitting side hash value from a content transmitting server 110 and a broadcast material ID. The business broadcasting server 150 receives data for the inspection of a receiving side including a receiving side hash value from a program transmission server 130 and a broadcast material ID. Furthermore, the business broadcasting server 150 determines whether the transmitting side hash value in the data for inspection of the transmitting side is coincident with the receiving side hash value in the data for inspection of the receiving side when the broadcast material ID in the data for inspection of the transmitting side is the same as the broadcast material ID in the data for the inspection of the receiving side.
