Last Sunday my iMac was stolen by a burglar. On Monday it showed up on 'find my mac'. Good police work and a lot of luck ended up in me retrieving my device that was on a location more than 50 meter from the 'find my mac' location. I think it would be possible to make an app that after 'find my mac' sends you to the right neighborhood, sniffs for the Wi-Fi MAC address on three devices, share the these measurements and triangulate for the exact position. This would make an outstanding tool for police and security services and every Smartphone has the hardware to do it.
- Is there already an app to do this? (won't spent months of programming to make something that already exists).
- Is there a sniffing app for iPhone or Android that also sniffs packages without connecting to the network (only the MAC address, not what is in the package) and detects the signal strength?
- Does someone know a simple triangulation algorithm?
- How about bluetooth to do the same?
