Ms. Pedro English 101 October 15, 2014 Access Granted Biometric devices authenticate a person’s identity by verifying unique personal characteristics. These devices translate a biometric identifier such as a fingerprint into a code that is compared with a digital code stored in a computer. If the digital code in the computer matches the personal characteristic code, the computer grants access. Example of biometric devices include fingerprints readers and face recognition system. A fingerprint reader, or scanner, captures curves and indentation of a fingerprint. Organizations use fingerprint reader to secure doors, computers, and software. For example a fingerprint reader can be set up to authenticate users before they can access a computer (Rossi). External fingerprint readers usually into a USB port. To save on desk space, some laptops include built-in fingerprints readers. A face recognition system captures a live face image and compares it with a stored image to determine if the person is a legitimate user. Some building use face recognition system to secure access to rooms. Law enforcement, surveillance systems, and airports use face recognition system to protect the public. Some mobile devices use face recognition system to unlock the device. Face recognition system are becoming more sophisticated and can recognize people with or without glasses, hats, facial hair, makeup, or jewelry, and with new hairstyles (Allensmith). Home and business users alike are using biometric security. Through a biometric identifier, such as a fingerprint, biometric devices can deny or grant access to programs, devices, computers, rooms and other locations. Biometric devices are an effective security technology. Works Cited Allensmith, Samantha Clare. Understanding Face Recognition Systems. 16 Sept. 2014. Course Technology. Web.
