At the end of 2004 and the beginning of 2005, one of our customers needs to improve the security in some tasks of the Workflow processes in Windchill PDMLink. We were evaluating different possibilities, and decided to add to those tasks a biometric verification of the fingerprint of the users.

We developed a specific page in Windchill to register the fingerprint of all the special users. To get the fingerprint, we use biometric mouses of SecuGen that incorporate a fingerprint sensor in the left side of the mouse.

The sensible tasks for these users, require fingerprint verification, so when the user clicks on the “Task Complete” button, the browser asks to the user to place the fingerprint over the sensor, and the task is completed only if that fingerprint has been registered as the valid fingerprint of the user trying to complete the task.
