Be it companies or households, everyone today is making use of keyloggers to maintain a record of all the activities done on computer. One kind of keylogger is the software keylogger. As the name suggests, software keylogger is required to be installed in the pc like any software.
On the other hand, the second kind of keylogger is the hardware keylogger does not require any installation but can be easily made use of by plugging it into the USB port or the PS/2 port of the pc which connects the keyboard to the computer. It tracks and records the keystrokes made from the keyboard. Even the passwords typed from the keyboard can be captured and recorded. In other words any and every activity done through the keyboard is logged to the internal memory of the keylogger. They begin operating from the minute the computer is switched on unlike their counterpart. With the help of a microcontroller, interpretation of the datastream between the computer and keyboard is enabled which is then passed to the non-volatile memory. Here is the reserve of data which is maintained and can be retrieved whenever needed by typing a password. If the keylogger features a strongly encrypted memory accessing the keystrokes locked inside the memory gets impossible if the password is not known that was used to encrypt the keystrokes.
This type of keylogger is more convenient to use than its counterpart of software keyloggers. The main reason is that it does not need any driver or software to be incorporated in the computer. Moreover, no booting of computer is needed to run this keylogger. It also enables recording and retrieveing data in two different computers unlike the software keylogger. Moreover, the ease of installation without the need of software or driver makes it compatible with any type of operating system running in the computer. Another major benefit of this feature is that in case of system crash down or hard disk failure or destruction, data stored in the internal memory of the keylogger would not be lost since it works on its own internal microprocessor. That is, the keystrokes secured in the internal memory of the keylogger would not be lost even if the computer crashes down for any reason may be.
Another major benefit of this type keylogger is that it is fully untraceable when passed through software or security scanners. This means that the user would not even have his employees, children or spouse know that they are being checked upon. Hence, it makes data tracking even more safe and secure than the software keylogger.
It is also very easy to carry as it is compact in shape and quite handy. It can be easily transferred one computer to another by being plugged into the ports of the different computers, hence making sharing of data much more convenient.
So if a company wants to have a backup of all its data, or wants to monitor its employees’ activities or a parent wants to keep a track of their kids’ activities, then hardware keylogger is the right choice!
Hardware keylogger-to the rescue of pc users!
