Other issues

Keystroke logging[edit]
Keystroke logging (often alleged keylogging) is a adjustment of capturing and recording user keystrokes. While it is acclimated accurately to admeasurement agent abundance on assertive accounting tasks, or by law administration agencies to acquisition out about actionable activities, it is aswell acclimated by hackers for assorted actionable or awful acts. Hackers use keyloggers as a agency to admission passwords or encryption keys and appropriately bypass added aegis measures.
Keystroke logging can be accomplished by both accouterments and software means. Accouterments key loggers are absorbed to the keyboard cable or installed central accepted keyboards. Software keyloggers plan on the ambition computer's operating arrangement and accretion crooked admission to the hardware, angle into the keyboard with functions provided by the OS, or use limited admission software to address recorded abstracts out of the ambition computer to a limited location. Some hackers aswell use wireless keylogger sniffers to aggregate packets of abstracts getting transferred from a wireless keyboard and its receiver, and again they able the encryption key getting acclimated to defended wireless communications amid the two devices.
Anti-spyware applications are able to ascertain abounding keyloggers and absolve them. Responsible vendors of ecology software abutment apprehension by anti-spyware programs, appropriately preventing corruption of the software. Enabling a firewall does not stop keyloggers per se, but can possibly anticipate manual of the logged actual over the net if appropriately configured. Arrangement monitors (also accepted as reverse-firewalls) can be acclimated to active the user whenever an appliance attempts to accomplish a arrangement connection. This gives the user the adventitious to anticipate the keylogger from "phoning home" with his or her typed information. Automatic form-filling programs can anticipate keylogging absolutely by not application the keyboard at all. Most keyloggers can be bamboozled by alternating amid accounting the login accreditation and accounting characters about abroad in the focus window.[13]
Keyboard are aswell accepted to afford electromagnetic signatures that can be detected application appropriate spying accessories to reconstruct the keys apprenticed on the keyboard. Neal O'Farrell, controlling administrator of the Identity Theft Council, appear to InformationWeek that "More than 25 years ago, a brace of above spooks showed me how they could abduction a user's ATM PIN, from a van anchored beyond the street, artlessly by capturing and adaptation the electromagnetic signals generated by every keystroke," O'Farrell said. "They could even abduction keystrokes from computers in adjacent offices, but the technology wasn't adult abundant to focus in on any specific computer."[14]
Physical injury[edit]

Proper ergonomic architecture of computer keyboard desks is all-important to anticipate repetitive ache injuries, which can advance over time and can advance to abiding disability.[15]
The use of any keyboard may could cause austere abrasion (that is, carpal adit affection or added repetitive ache injury) to hands, wrists, arms, close or back. The risks of injuries can be bargain by demography common abbreviate break to get up and airing about a brace of times every hour. As well, users should alter tasks throughout the day, to abstain overuse of the easily and wrists. When inputting at the keyboard, a being should accumulate the amateur airy with the elbows at the side, with the keyboard and abrasion positioned so that extensive is not necessary. The armchair acme and keyboard tray should be adapted so that the wrists are straight, and the wrists should not be adequate on aciculate table edges. Wrist or approach rests should not be acclimated while typing.
Some adaptive technology alignment from appropriate keyboards, abrasion replacements and pen book interfaces to accent acceptance software can abate the accident of injury. Abeyance software reminds the user to abeyance frequently. Switching to a abundant added ergonomic mouse, such as a vertical abrasion or joystick abrasion may accommodate relief. Switching from application a abrasion to application a stylus pen with clear book or a trackpad can abate the repetitive ache on the accoutrements and hands.
Bacteria[edit]
Some keyboards were begin to accommodate 5 times added bacilli than a toilet seat.
