I'm having some problems at college. As for the background: My college is astoundingly stupid, in that there are per-computer logon accounts, instead of per-user logon accounts. Leaving out the security risks and plethora of other negative points, the accounts, while unique for each machine all use the same password. The following problem has got me beat: how can i lock my screen.
I have done some googling, but no glory. What I'm thinking is, if i were to install a low level mouse and keyboard hook, could i just eat all the keyboard and mouse messages until the user took an action to disable them (type a password etc)?. I realise that ctrl+alt+delete cannot be caught (short of replacing the keyboard driver), but if the user cannot use the mouse or other keyboard keys, invoking the task manager/windows security panel dosnt help them a lot. As a bonus perhaps i could use ogl or whatever to black the screen (keeping it on top of the task manager/preventing task manager from minimizing it might be a problem).
Anyway, let me know your thoughts/problems/criticism, and who knows one day my college computer will be safe from those nasty little peers of mine.
