DNA biometrics

DNA biometrics involves using a person's unique genetic code to identify them, much like a fingerprint. Every individual’s DNA has specific patterns that are distinct, except for identical twins. For identification, a small sample of cells (from blood, saliva, or hair) is analyzed to extract DNA and identify these unique patterns. This method is highly precise and is used in forensics, security, and personal identification, ensuring accurate matching. Unlike fingerprints, DNA can provide confirmation even after a long period, making it a powerful tool for verifying identity reliably.
