The company that was pitching my employer retina scanners on data center doors 20 years ago had an idea like this. Left eye gets you in, right eye gets you in and alerts security.
- tazjin 5y agoAs long as the sides are the employee's choice (i.e. the threat actor needs to not be able to know which eye is the duress one).
- hanniabu 5y agoGood point, that's a very important requirement
- HomeDeLaPot 5y agoAnd you'd want to hide the eye choosing/scanning process so nobody could just watch an employee to figure out their preference.
- Verdex 5y agoScanner is something you look in with both eyes. And then while your eyes are completely hidden you close one eye. Heck. You could set it up so that it scans both eyes and then does a second scan where you choose what your ok signal is (both eyes, right only, left only, no eyes).
- Draken93 5y agoYeah i think technicaly it could work. But I actually think that is a terrible idea. Humans have a lot less self control then we think. This will lead to many false alarms.
- LeonM 5y agoThis is also very typical for regular alarm systems with a keypad. A PIN disarms the alarms system, the same PIN + 1 disarms the alarm system and notifies security.
- thomascgalvin 5y agoI worked at a place where the duress code was ROT5: 1234 was your normal access code, 6789 lerted security.
- Biganon 5y agoYou're supposed to ROT5 mentally while in a state of high stress?
- thomascgalvin 5y agoIt wasn't a well-considered plan. It also wasn't highly advertised. I found out because someone happened to mention it to me one day.
- danachow 5y agoIt doesn’t sound quite as onerous if you just memorize two 4 digit numbers by rote. But yes I agree the ROT5 is a dumb flourish.
- tragomaskhalos 5y agoAlso consider that most of us recall an oft-used PIN as much via muscle memory as a pattern on the keypad rather than as the actual digits, which would make ROT5'ing it that much harder.
- HPsquared 5y agoCould use the method in The Wire: press the key on the opposite side to the usual key (e.g. 8 instead of 2, 6 instead of 4, etc.)
- Haegin 5y agoBetter hope nobody uses 5555 as their pin then!
- accountofme 5y ago
- HPsquared 5y agoThis could also work with fingerprint scanners.
- koolba 5y agoCould also blink Morse code. It’s been done before: https://m.youtube.com/watch?v=rufnWLVQcKg https://m.youtube.com/watch?v=rufnWLVQcKg
- eps 5y agoIf you wonder whether it's a video of an american pow blinking "torture" during an interview - yes, it is.
