Access control systems are put in place to secure privileged information. Their design allows only a limited number of people to have access to certain data.
Access control systems are a common part of everyone’s daily life. Anything that requires a password or has a restriction placed on it based on its user is using an access control system. For example, when a person views his bank account information online, he must first enter in a specific username and password. Without this information, a person has no access to his account.
As technology has increased with time, so have these control systems. A simple four-digit PIN and password are not the only options available to a person who wants to keep information secure. For example, there are now locks with biometric scans that can be attached to locks in the home. The Biometrics Institute states that there are several types of scans. These scan-based locks make it impossible for someone to open the door to a person’s home without having the right physical features, voice or fingerprint. In some instances, such as with large businesses, the combination of both a biometric scan and a password is used to create an ideal level of security.
