Post by thread:[PIC]: PS/2 Keyboard logger?

The FBI has gadgets that do this, they use them all the time, maybe they have a support list you can post a message to :-) Sorry I couldn't resist.

Actually this is already a product; I'll look it up, but this has come up before. Basically you set it up to log key events and leave it. You can get keystrokes back by opening up a notepad like program and type in the password, and the logger will rekey the stored keyboard strokes. The entire package looks like a keyboard cable extension with a larger than normal socket. -Dal ----- Original Message ----- From: Justin Fielding <spam_OUTj.fieldingTakeThisOuTBTINTERNET.COM> I would like to build a small device with which I can log all keypresses of a keyboard into an eeprom.

These links should get you started on the standards and possibly some code. Hope this helps.

Here's a few paragraphs from the article, before links listed below: Keyboard 'snooping' device finds market. Christchurch company KeyGhost is poised for international success with its keyboard 'snooping' device. The company has sold 1500 units of its KeyGhost product in its first year of operation and signed up distributors in the United States, Germany, Australia, and Canada. The hardware device records every keystroke made on a keyboard, with password-protected logs that the user cannot tamper with. -- snip-- KeyGhost is embedded in a keyboard or PC and cannot be bypassed. --snip-- The device ranges in prices from US$139 to $349, with the three models available holding about a week, a month, or several months of typing. She says the main market in the longterm will be the corporate sector. --snip-- KeyGhost can be used in English, German and Arabic. --snip-- Some software developers are also buying KeyGhost as a backup, so that if their systems crash their code is not lost. The device can also help them debug programs - if a program crashes, the combination of keystrokes that led to this can be pinpointed and the code subsequently corrected. KeyGhost was originally developed by Canterbury University students frustrated at losing work when their computers crashed. --snip-- The device has a bigger capacity than any of its competitors, she says, and is well-positioned to lead the market. ----[ end of selected extracts from InfoTech article]------ {Original Message removed}
