1. Biometric Verification

Overview

Biometric verification is one of the most secure methods of identity authentication, leveraging unique physical or behavioral characteristics of individuals to confirm their identity. This method is increasingly popular due to its accuracy and convenience, as users do not need to remember passwords or carry physical tokens.

Biometric systems create templates from captured biometric data using various methods, each tailored to specific types of biometric characteristics. Here are the main ways templates can be created, along with examples:

a. Fingerprint Templates

Method:

• Minutiae Extraction: This involves identifying and encoding specific features of fingerprints, such as ridge endings and bifurcations.

Example:

• A fingerprint scanner captures the user's fingerprint and analyzes the patterns, generating a template that encodes the location and types of minutiae points.

b. Facial Recognition Templates

Method:

• Facial Landmark Detection: This technique involves identifying key points on the face, such as the eyes, nose, and mouth, to create a unique template.

Example:

• A camera captures an image of the user's face, and the system processes it to create a template based on the distances between facial landmarks, resulting in a numerical representation of the face.

c. Iris Recognition Templates

Method:

• Pattern Recognition: Iris recognition systems analyze the unique patterns and textures of the iris.

Example:

• An iris scanner captures a high-resolution image of the user’s eye and extracts features such as the patterns of furrows and rings in the iris, creating a detailed template for verification.

d. Voice Recognition Templates

Process:

Username and Password Entry:

The user begins by entering their registered username and password on the login page of the application or service.

The system verifies the entered credentials against the stored user information in the database.

One-Time Code Generation:

Upon successful entry of the username and password, the system generates a unique one-time code (OTP). This code is typically time-sensitive and valid for a short duration (e.g., 30 seconds to a few minutes).

The system sends this OTP to the user’s registered mobile phone number via SMS or to their email address, depending on the user’s preference.

Code Entry:

The user receives the one-time code and is prompted to enter it into the application.

The entry field for the OTP is usually separate from the password field to emphasize that it is an additional layer of security.

Code Verification:

Once the user enters the OTP, the system verifies it against the generated code stored temporarily during the authentication session.

If the code matches and is still valid (i.e., not expired), the user is granted access to the application or completes the registration process.

Access Granted:

After successful verification of both the password and the OTP, the user is logged in or registered, allowing them to access the full features of the application.

If the code is incorrect or has expired, the user is prompted to request a new code or re-enter the previously entered information.

Security Measures:

To enhance security, the system may implement additional measures, such as rate limiting (restricting the number of OTP requests) and account lockouts after multiple failed attempts.

Users may also be given the option to use backup codes for authentication in case they lose access to their primary method of receiving OTPs.

While it is relatively easy for users to understand and implement, KBA is notably vulnerable to social engineering attacks and guessing.

Process:

Question Selection:

During the registration process, users are prompted to select a set of personal questions from a predefined list. Examples of common questions include:

What is your mother's maiden name?

What was the name of your first pet?

What city were you born in?

Users may also have the option to create custom questions, which can provide additional personalization.

Answer Submission:

Users provide their answers to the selected questions. These responses are securely stored in the system alongside their account information.

Verification Request:

When a user attempts to log in or recover their account, they may be prompted to answer one or more of the personal questions they previously selected.

The system presents the questions without revealing the answers, ensuring that only the user knows the correct responses.

Answer Comparison:

The system compares the user's responses against the stored answers to determine if they match.

If the answers are correct, the user is granted access to their account or allowed to proceed with the recovery process.

Handling Incorrect Answers:

If the user provides incorrect answers, they may be given the option to try again or answer additional questions.

After multiple failed attempts, the account may be temporarily locked or flagged for further security checks.

Vulnerabilities
