Title:
METHOD AND SYSTEM FOR TRACKING ELECTRONIC DATA AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP3483782
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a data tracking system capable of properly specifying the transmission source of electronic data to be distributed through a network on the side of reception.
SOLUTION: A data tracking system 1 is constituted by providing plural data repeaters 10 chain-connected on the network and a managing system 20 equipped with a means for bidirectionally communicating with the respective data repeaters 10. Each data repeater 10 analyzes the identifier of a low-order layer for carrying electronic data on a network L and based on this analyzed result, the preceding device passing the electronic data is specified. When the specified device is provided with a function equal with the present device, the further preceding another device passing the electronic data is specified. Besides, the analyzed result of the present device is reported to the managing system 20 together with prescribed identification information. Based on the information reported from the respective data repeaters 10, the managing system 20 specifies the distribution route of the relevant electronic data.
