Quote from: CharasBros on April 16, 2012, 01:59 pmhttp://ob-security.info/?p=393here is one good example of such system called password pad. can be very handy for creating complicated and same time easy to remember passwords.That's an excellent idea using the same principle, thanks! Of course as the article says you would have to use this in combination with a word or phrase you'd memorised to make it extra secure, otherwise you'd be reducing the combinations of passwords considerably.My concern about using this would be that in countries like the UK, under the Regulation of Investigatory Powers Act (RIPA) a person can face up to two years' imprisonment for failing to divulge their password to the authorities. It would be impossible to deny that you had encrypted data if you had something like this on your person - that said I'm sure it would be possible to use it as a bookmark or keep it somewhere safe where they wouldn't find it.A friend of mine used to keep a list of his clients in a sealed envelope inside his own mailbox. His house was raided twice and it never occurred to the Police to search there. :-)V.
