    I've been thinking about an ordinary person being addressed by a cop, for whatever reason (say he pulls you over for speeding). Usually, we take it for granted that a person driving a marked police car and wearing a police uniform is a genuine police oficer. They also carry a badge to further prove who they are.

    However, all of those paraphernalia are relatively easy to counterfeat or steal. In the digital age, shouldn't there be some more reliable way for a cop to prove his authority? I am particularly curious if this can be achieved without ordinary citizens having to carry some sort of chip-card reader or other electronics.

    Of course, any authentication technique that works in this context would also have many other uses.

    If it is anything a phony cop would have to show, it probably could also be stolen.

    I believe this could be done with help of digital signatures. Say the government issues a digitally signed document with the name, surname and photo to every police officer. He sends the document to your mobile(or PDA or some sort of specialized gadget) via Bluetooth and you check the validity of signature.

    All the necessary technologies are present now. All you need is software and will of government to introduce the system.

    The only issue: your mobile should have Internet connection to check whether the signature was not revoked recently.

    Sorry to revive the topic a month later, but I thought it was worth nothing that Blackinton already has a digital system on the market called SmartShield and EID (Enforcement Identification). I think it uses the RFID chip.

    Anything that a cop should carry with him can be stolen or can simply be duplicated.

    But if we issue a digital card to everyone with and state "the person is a cop" in the card if owner is a cop , it would be great.

    Ok. A cop has pulled me over. As often advised by law enforcement I have my hands and arms in plain view high on the steering wheel.

    How would this work?

    I'm reminded of the Lensman series by E.E.'Doc' Smith. Those familiar with the series will immediately see the parallel. Those who wish to bathe in 1940's pulp fiction, with an imaginative streak, should get reading.

    The system I was talking about allows remote deactivation and authorization of the badge. I don't know if people who the officer stops can check the badge authorization, but if they can it might be a good idea. Where I live nobody ever questions the police, though, and I don't think we want to start a system of authorization checks which we might see as disrespectful.
