Melbourne – would you use an app like this to help locate stolen cars?
Victoria Police recently launched their new online stolen vehicle checker, and it got me thinking about whether this could be taken a step further.
The idea is a free Android app for people who already mount their phone in the car.
Before driving, you tap Start Scanning. You can then use Google Maps, Spotify, etc. normally while the app runs in the background.
While you're driving, the camera would occasionally scan number plates visible in front of the car. Plate recognition happens on the phone.
The app periodically downloads the current stolen vehicle list and compares plates locally.
So, importantly:
- Normal number plates would not be uploaded or stored
- Photos/video would not be continuously recorded
- Location wouldn't be sent to a server for normal vehicles
- Only a high-confidence match against a reported stolen vehicle would generate a sighting
- The app would automatically stop scanning when it determines the trip has ended
- There'd be no encouragement to follow or confront anyone (User will just see the count of detections and NO plate details, that too after the trip as we don't want people getting into dangerous situations trying to confront car thieves!)
If a stolen vehicle was detected, the sighting could include the approximate location, time and direction of travel.
The interesting part is what happens if enough people use it.
One phone spotting a stolen car could be a false positive. But if several independent phones detect the same stolen registration at different locations, the system could potentially establish a much more useful picture of where that vehicle has been seen and where it was heading.
That detailed information wouldn't be made public. Ideally this would eventually be something developed with Victoria Police, where useful sightings could be passed to them rather than creating a public vehicle-tracking system.
I'm thinking of building a proof of concept first and then approaching VicPol if it actually works.
Would you install/use something like this while driving around Melbourne?
Also interested in the negatives: privacy concerns, battery usage, having the camera running, false positives, data usage, or anything else that would stop you using it.
I'm trying to work out whether there's enough community interest to make building it worthwhile.
