What is Biometric Computer Security?

biometric computer security system requires the user to provide a fingerprint (or other biometric) to the system, which is then verified against a stored biometric template.

How does Anti Virus Software combat Viruses? 陿蚟陿翿

Antivirus software (or anti-virus) is computer software used to identify and remove computer viruses, as well as many other types of harmful computer software, collectively referred to as malware. While the first antivirus software was designed exclusively to combat computer viruses, most modern antivirus software can protect against a wide range of malware, including worms, rootkits, and Trojans.

What type of information should be encrypted? 3 Examples

encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is encrypted information (in cryptography, referred to as ciphertext). In many contexts, the word encryption also implicitly refers to the reverse process, decryption (e.g. “software for encryption” can typically also perform decryption), to make the encrypted information readable again (i.e. to make it unencrypted).
