Just a passing thought…
It seems you (I) hear more and more these days about people being required to give up their password to authority figures, to allow said figures access to the contents of their electronic devices, such as Hard Disk Drives and Cellphones and the like. Sometimes these are lawful requests, sometimes they are not. Regardless of the reason for the request, I have to wonder:
Is there currently any such protection system, that would, upon receiving a correct password unlock the data, but upon receiving a different password, automatically and permanently scramble, erase, or otherwise make unreadable the data on the device? A kill switch, in effect. Only the authorized user would know that this password isn’t going to open the device, but destroy it instead.
If so, where could I find such a device? If not, why not? And is this a potential untapped market, were I to develop such a thing? What kind of legal obstacles currently exist to such a thing, aside from the obvious ‘obstruction of justice’ angle if used in such a manner as to make such use illegal?
Do Not Need Answer Fast, not yet at least.
