However challenges like privacy concerns, data security and potential misuse of biometric data must be addressed.
The goal is to determine the degree of similarity and thereby verify the individual’s identity. Here’s a detailed explanation of how this process unfolds:
- Biometric Features Data Collection: The initial step involves collecting biometric data from an individual. This data typically includes unique physical or behavioral features such as fingerprints, facial patterns, iris scans, voice patterns or even behavioral traits like keystroke dynamics.
- Creation of Biometric Template: Once the biometric data is collected it undergoes a specific process to create a biometric “template” or reference model. This template serves as a digital representation of the individual’s unique biometric features. The template is carefully crafted to retain key information about the individual’s biometric traits while ensuring privacy and security.
- Storage of Biometric Template: The biometric template which encapsulates the unique characteristics of the individual’s biometric features is securely stored in a database or on a secure server. It is essential to safeguard this information to prevent unauthorized access or misuse.
- User Authentication Process: When a user attempts to access a system or service requiring authentication their biometric features are again captured and converted into a comparable digital representation.
- Matching Process: The new biometric data obtained from the user is then compared with the pre-existing biometric template stored in the reference model. Advanced algorithms are employed to analyze the data and assess the level of similarity between the live biometric data and the stored template.
- Similarity Assessment: The comparison results in a similarity score or a match score, indicating how closely the user’s biometric data aligns with the stored template. This similarity score is evaluated against a predefined threshold to determine if the match is sufficient for authentication.
- Authentication Decision: Based on the similarity score and the predetermined threshold, a decision is made regarding the user’s authentication. If the similarity score meets or exceeds the threshold, authentication is successful granting the user access to the system or service. However if the similarity score falls below the threshold authentication is denied, and access is restricted.
Using Biometrics for Security
Biometric authentication is a modern security technique that utilizes a unique physical or behavioral characteristic of an individual to establish their identity. This method is highly reliable and is used in various applications from unlocking smartphones to securing sensitive data in high-level government facilities.
