Fingerprint
1. When referring to computers and security, a fingerprint refers to any trace of information left by someone. Often, if someone has gained unauthorized access to a computer or network, an administrator or security agent may look for any fingerprints left by the attacker, such as IP addresses, host names, etc. This can be compared to a crime scene detective looking for fingerprints at a crime scene.
2. When referring to computer hardware, a fingerprint scanner or fingerprint reader is a hardware device that verifies a user or enters password information by scanning their finger.
In the picture to the right, is an example of a fingerprint scanner by Microsoft. Computers that do not already include a fingerprint scanner can connect devices such as these to their computer USB ports.
