It relies on the distinctive ridges and valleys present on an individual's fingertips to establish identity. Many of us use it daily on our phones and computers. Fingerprint scanners provide a convenient and secure method for unlocking devices and granting access to restricted areas.

Since fingerprint patterns are unique to each individual, fingerprint scanning is a highly secure application of biometrics. It is difficult to forge or replicate fingerprints, providing a robust authentication method and reducing the risk of unauthorized access. Fingerprint scanning is convenient and fast. Users can authenticate themselves by simply placing their finger on the scanner, eliminating the need to remember complex passwords or carry physical tokens. Fingerprint scanners are widely available and relatively cost-effective to implement. The technology is mature and has a proven track record in various applications.

DNA Sequencing

The use of DNA (Deoxyribonucleic Acid) in Identity and Access Management (IAM) is a relatively new and emerging area of biometric authentication. While DNA analysis has been predominantly associated with forensic and genetic applications, its potential use in IAM is an intriguing at times terrifying concept.

DNA is an individual's genetic code, unique to each person (except in the case of identical twins). It contains a vast amount of genetic information that is specific to an individual and remains constant throughout their lifetime. This uniqueness makes DNA an appealing biometric identifier for IAM.

DNA analysis offers a high level of accuracy and uniqueness. The chances of two individuals having the exact same DNA profile are extremely low, making it an effective means of identifying and differentiating individuals in IAM systems. Despite the potential advantages, the use of DNA in IAM faces several practical limitations.
