PSWeb Facial Recognition tool, what is it? • It’s a tool allowing the user to take any facial

photo/image and compare it to all previously taken booking photos from our jail for possible matches.

• It can search using either a photo or composite sketch of a face image.

• It scans facial points to compare. • The search process will score comparisons and

list the top five (5) possible matches. • At this time it will only search the Washington

County Jail inmate photo collection.

Where do I find the Facial Recognition tool in PSWeb?

• Log in to PSWeb • On any page, click the Search tool icon (magnifying glass). • Type “Facial” in the search box and click “GO”.

• The Facial Recognition report will be listed in the search results.

• Click on the report name “Facial Recognition” to navigate to the facial recognition tool.

• The starting page is where you will load the photo/image being compared to and execute the scan and search process.

• You will need to provide a valid reason for the search, and an Incident or Case Number before the “Choose Photo” button will appear

• Using the file explorer, navigate to where the image you are wanting to search is located.

• Select the image and click “Open”.

• The search tool scan will begin. • When completed, a listing of possible matches will be returned in the box at

the right.

• Possible matches will be displayed one at a time. • To navigate through all images returned from the search, click on the left and

right arrows below the image to view each one.

• Side by side comparison after clicking “Enlarge Compare” button.

• As you can see despite a potential result being returned, it still requires human interpretation to determine if there is a potential investigative lead.

• In this case OJ Simpson was never found to be lodged in our jail but the tool compares strictly facial measurements for possible matches, hence the image returned above as a result.

• Absent other evidence, a facial recognition search result alone will not constitute probable cause for arrest or to seize any person.

• Any questions can be emailed to “WCSO Law Enforcement Technology” or call the LET general line during business hours at x2572.
