As shown in FIG. 3, this program is a user site registered in a Web server (4) through a user terminal computer (10) connected to the Internet (2) and installed with this program. Monitoring the Web file data, and collating the Web file data with the backup data at the time of uploading the Web file data periodically or as necessary,
When a tampering with the Web file data is found by a hacker, a warning is displayed on the screen of the user terminal computer (10), and the tampered Web file data is repaired.

The collation module (16) of the program
Is composed of a collation data creation unit (22), a data collation unit (24), a data acquisition unit (26), a data storage unit (30), and a Web site connection unit (32) shown in FIG. The control module (20) constitutes a website monitoring means (34), and the repair module (36)
Constitutes a data restoration means (36).

In the figure, (38) is a data display means, (4)
6) is an initial screen display means. Each of the above means functions under the control of the CPU (40) of the user terminal computer (10). In the figure, (42) is ROM, (44) is RA
M. The collation data creating means (22) is a Web server.
The data monitoring means (26) is controlled by the control of the site monitoring means (34).

The means for connecting to a Web site (32) connects the user terminal computer (10) to the Web server (4). The data fetching means (26) stores the Web file data (1
2) is loaded into the user terminal computer (10).
The captured Web file data (12) is stored in the storage device of the user terminal computer (10) by the data storage means (30).

The collation data creation means (22) further controls the data acquisition means (26) to store the backup data (14) at the time of uploading the Web file data to the Web server (4) at the user terminal computer (10). Or from the memory of the Web server (4). The backup data (14) of the Web file data is stored in a predetermined file in a storage device of the user terminal computer (10) by the data storage means (30).

The data collating means (24) of the data collating module (16) controls the Web file data (12) and the Web file data taken into the user terminal computer (10) under the control of the Web site monitoring means (34). The backup data (14) is checked to determine whether they match each other. This match determination is configured so that either partial collation or full collation can be selected.

In the above configuration, when the program installed in the user terminal computer (10) is operated, the initial screen display means (46) operates, and the initial screen of the program is displayed on the screen of the user terminal computer (10).
