<P>PROBLEM TO BE SOLVED: To track the leakage origin of information by obtaining a print log by printing all print data from a client side through a server, and storing the obtained print log and the print data. <P>SOLUTION: A server device 3 is connected through a network 1 to a client device 2 and a printing device 6. Print data generated by the client device 2 are transmitted to the server device 3 (S1), and the server device 3 stores the print data and print history information including the information of the client device 2 in a storage device 4 (S2). The server device 3 transfers the print data to the printing device 6 (S3), and the print data are printed out from the printing device 6 (S4). At that time, the printing device 6 stores the print result in a storage device 7 as the print log, and adds the stored print log in the storage device 4 (S5). When the leakage of the information is generated, the server device 3 analyzes the print log stored in the storage device 4 to specify the leakage origin of information by an auditing program 5. <P>COPYRIGHT: (C)2004,JPO |
