Meredeth, I don't know if this is too 'James Bond' for you or if I'm just totally crazy, but I designed this image for you to look at. Being in the military and working in several police stations I have witnessed high security-guarded areas including Parameter-based Access Stations.
(Pass the yellow line while someone else is gaining entry and you will literally be shot) I'm sure you've heard of Graphical Password techniques, many real-life industrial designers use them for such things as gaining entry to a department, car or to execute a certain action on a control panel or cockpit. Graphical Passwords are still not widely used but there are several advantages to it. (Please note that the wording, character symbols, colours, etc., are simply there to serve as an example.) Advantages are: 1. The user is able to physically see their pad-selection 2. It is impossible for an intruder to know how many characters are needed (Whether it's 8, 9, 10, 11, 12, 13, 14, 15, 16 digits long) 3. User is prompted to pay attention due to the 24 hour lockdown possibility 4. User has been informed that their IP address has been recorded 5. User has been informed that they only have 2 chances to enter 6. The character symbols can be whatever the team decides for it to be 7. Physical combinations are easier to remember then straight jargon password (e.g., someone can punch in a pattern of a cross, or 'V' shaped symbol) I have not thoroughly investigated this, and I'm not totally sure what the disadvantages are. Maybe we can open this up for discussion? I hope this has been a form of help or inspiration to you.
