Based on a large database which contains IP addresses associated with individual cities and countries, WWP is able to identify the exact location of a particular respondent by capturing his/her IP address upon launch of a website or survey.

Through this process, we are able to identify users who purport one location in a survey, but who have entered the website or survey using an IP address that does not verify that location.

If a user enters a location that is not verified by his/her IP address, he/she will not be allowed to continue.

This simple yet effective security option prevents multiple users originating from one IP address from entering the same survey. In addition, multiple users with the same password will not be permitted to enter that survey.

A script will check each participant as they enter a survey. If a user enters more than once, the administrative configuration will not allow the user to register.
