Screaming Cell Phones
Does it pay to scream if your cell phone is stolen? Synchronica, a mobile device management company, thinks so. If you use the company’s Mobile Manager service and your handset is stolen, the company, once contacted, will remotely lockdown your phone, erase all its data and trigger it to emit a blood-curdling scream to scare the bejesus out of the thief.
The general category of this sort of security countermeasure is “benefit denial.” It’s like those dye tags on expensive clothing; if you shoplift the clothing and try to remove the tag, dye spills all over the clothes and makes them unwearable. The effectiveness of this kind of thing relies on the thief knowing that the security measure is there, or is reasonably likely to be there. It’s an effective shoplifting deterrent; my guess is that it will be less effective against cell phone thieves.
Remotely erasing data on stolen cell phones is a good idea regardless, though. And since cell phones are far more often lost than stolen, how about the phone calmly announcing that it is lost and it would like to be returned to its owner?
