To provide a driving history management system that receives driving position history information measured by an on-vehicle device mounted on an automobile and recorded in a memory by a roadside wireless device or the like, and charges a toll or the like based on the travel history information, thereby preventing falsification of the driving history information recorded in the memory of the on-vehicle device.SOLUTION: When an on-vehicle device 100 passes through a wireless communication area of a roadside wireless device 110, driving position history information of the on-vehicle device 100 is transmitted from the on-vehicle device 100 to the roadside wireless device 110, and an electronic signature by a private key of the roadside wireless device 110 is applied to the driving position history information and is stored. At that time, by generating an electronic signature for a hash value, which is a combination of the driving position history information and electronic signature information given by the same exchange with the roadside wireless device 110 in the previous time, a recursive and continuous signature chain, i.e., hysteresis signature is formed.SELECTED DRAWING: Figure 1

    【課題】自動車に搭載された車載装置によって測位されメモリに記録された走行位置履歴情報を、路側無線装置等によって受信し、その走行履歴情報にもとづいて通行料金等を課金する走行履歴管理システムにおいて、車載装置のメモリに記録された走行履歴情報の改ざんを防止する。【解決手段】路側無線装置110の無線通信領域内を車載装置100が通行する際に、車載装置100の走行位置履歴情報を車載装置100から路側無線装置110に送信し、路側無線装置110の秘密鍵による電子署名を走行位置履歴情報に施して保存するようにし、その際に、走行位置履歴情報に加えて前回の路側無線装置110との上記同様のやり取りによって施された電子署名情報を併せたハッシュ値に対する電子署名を生成するようにすることにより、再帰的、連続的な署名連鎖、すなわちヒステリシス署名を形成する。【選択図】図1
