Biometric identification is a technology that uses unique physical or behavioral traits to verify a person's identity. Common biometric traits include fingerprints, facial recognition, iris patterns, and voice recognition. This method is often used in security systems, such as smartphones and access control systems, to ensure that only authorized individuals can gain entry. The process involves capturing a biometric sample, which is then compared to stored data in a database. If the sample matches an existing record, the individual is authenticated. Biometric identification is considered more secure than traditional methods, like passwords, because it relies on traits that are difficult to replicate or steal.
