Abstract

A user inserts a magnetic card to a magnetic card reader, and inputs his/her electronic signature and dealing data through an input device. The input dealing data are recorded on an electronic account data file together with the electronic signature. The input data are also recorded on a log file after encryption. An administrator inserts his/her IC card to an IC card reader/writer for updating the dealing data. The IC card reader/writer collaborates with a SAM to certify the inserted IC card (medium verification). A finger print recognizer obtains the administrator's finger print to compare it with finger print data stored in a finger print file (user verification). If both medium verification and user verification are passed, a controller decodes log data in the log file. After the log data are decoded, the administrator is allowed to access the electronic account data file for to update data. Data regarding to the update done by the administrator are also recorded on the log file after encyption.

Dependent claims

An electronic data management system which comprises a controller for executing a program stored in a memory while being connected to an input device for data input, storage units, a data reader for reading data regarding an encryption key and physical characteristics of an operator stored in a first recording medium, a medium verification device which stores an encryption key for verifying said first recording medium, and a physical characteristic data obtaining unit, wherein

said storage units comprise a first storage unit which stores an electronic data record file including electronic data, a second storage unit which stores a log file including log data representing an input or update log of the electronic data recorded on said electronic data record file, and a third storage unit which stores a physical characteristic data file which pre-stores data on physical characteristics of a certified operator,
said input device inputs electronic data to be recorded on said electronic data record file, and update data to update the recorded electronic data,
said medium verification device verifies whether said first recording medium from which said data reader has read data is a certified medium or not based on said encryption keys of both of said first recording medium and said medium verification device,
said controller executes the program stored in said memory to:
store log of the electronic data input from said input device in the log file;
store the electronic data input from said input device by affixing thereto an electronic signature in the electronic data record file;
determine that said system is operated by a certified operator only when said medium verification device verifies that said first recording medium is a certified medium, and all three of the data on physical characteristics of an operator obtained by said physical characteristic data obtaining unit, the data regarding the physical, characteristics of an operator which said data reader has read from said first recording medium, and the data on the physical characteristics stored in said third storage unit, correspond to one another,
allow the operator to input the update data through said input device to update the electronic data in the electronic data record file when said first recording medium and the operator are certified;
update the electronic data in the electronic data record file by affixing thereto an electronic signature in accordance with the update data input by said input device;
and
store log of the update data input by the input device in the log file.
