Does Hardware Keylogger Legally Exist?
While hardware keyloggers may be useful in fraud and identity theft, they do have valid uses. In testing software, knowing exactly what a user did is useful to programmers. That can effectively pin-point a problem in code. Employers can use them to monitor the progress and productively of employees. Some manufacturers advertise hardware keyloggers as a form of backup, keeping each page you write even if your computer is power. While arguments can be made that hardware keyloggers are more often used for malicious reasons, in the right hands, they are a useful tool.
Have hardware keyloggers been found on public computers?
Yes. Earlier this year, there was a case where hardware keyloggers were found on library computers in Manchester. In three separate locations, the devices were found plugged into public access machines. The type used here was the kind that looked like a USB flash drive. Authorities advise greater vigilance, especially for the employees, but users need to be alert too.
It should be noted that it is generally unwise to use public computers for sensitive data. E-mail, banking sites, and credit card use should be avoided when on these computers.
