I think you have something here. I assume you want to put unencrypted personal or employment documents on a reader and don't want unauthorized access to it thus exposing some personal or employer data. You'd want something that prompted for the password.
Your user handle here on Mobileread doesn't say what device you have (or are considering) but if you have a Kindle, they have it out of the box. They have a global password that blocks all access to the Kindle at startup until the correct password is entered.
With a Kindle 3, from the Home screen, press the "
Menu" button then using your 4-way controller select "
Settings" and page through 2 screens to the heading
Device Password and click "
turn on". It will prompt you for the password and a reminder phrase. From then on it will require a password to start it up from shutdown or from sleep. You can turn the feature off by following the same process only it will now say "
edit" "
turn off".
On the Kindle Touch, starting from the Home screen select
Menu then
Settings then
Device Options and finally
Device Passcode.
I haven't checked on this (and I probably should) but I think it's possible to set a Kindle to require a password to allow anyone using it to buy books directly from Amazon with the Kindle. This setting is done online through your My Account page at Amazon.com.
