<p>PROBLEM TO BE SOLVED: To provide an abnormal input detecting device that detects raw data of abnormal input among the pieces of data inputted by a consumer. SOLUTION: Raw data (keyword) inputted by the consumer to a Web server 6 through consumer systems 8a, 8b, 8c are acquired (step S10, an input ratio with respect to specific raw data included in the acquired raw data is calculated (step S11) as calculated ratio data, and correlation data of the specific raw data are extracted (step S12) from a correlation data storage part 22. The calculated ratio data and the correlation data are compared (step S13), and, if the calculated ratio data deviate from the correlation data by a given value or more (step S14), a warning about the abnormality of the specific raw data input is displayed (step S15) on a display part 28.</p> |
