Biometrics


Biometric authentication is a security process that uses unique physical or behavioural characteristics to verify individuals’ identity. Here are three commonly used methods, along with their advantages and disadvantages:

Fingerprint Recognition: Biometric technology that identifies individuals based on the unique patterns in their fingerprints.

Advantages:

·       Highly unique fingerprints are distinct even among identical twins.

·       Fast authentication with minimal user effort.

·       Compact and easy-to-integrate scanners.

Disadvantages:

·       Can be compromised if fingerprints are stolen or copied.

·       May not work well for individuals with worn or damaged fingerprints.

·       Some materials (e.g., gloves or moisture) can affect accuracy.

 

Facial Recognition: Works by matching the faces of people within range of special cameras identifying individuals by analysing the unique patterns of their facial features.

Advantages:

·       Contactless authentication, making it convenient and hygienic.

·       Works well in various environments and lighting conditions.

·       Can be integrated with cameras for seamless authentication.

Disadvantages:

·       Privacy concerns arise due to potential surveillance and data storage.

·       May be tricked by high-quality photos or deepfake technology.

·       Accuracy can be affected by changes in appearance (e.g., aging, makeup, facial hair).

 

Iris Scanning: Biometric identification method that utilizes the unique patterns in the iris, the coloured part of the eye, to identify individuals.

Advantages:

·       Extremely accurate and reliable due to the unique patterns in the iris.

·       Works well even in low-light conditions.

·       Harder to spoof than fingerprints or facial recognition.

Disadvantages:

·       Requires specialized cameras, making it expensive to implement.

·       Can be affected by eye conditions or reflections from glasses.

·       Some users find it uncomfortable or invasive.

Robust password and encrypted data

  Password Policy and Strong Password Create a robust password policy is essential for ensuring and safeguarding the security of user accounts and protecting sensitive information from unauthorized access. A strong password should mandate: ·        At least 16 characters long. ·        A mix of uppercase and lowercase letters. ·        Numbers, and special characters. ·        It should avoid common words. ·        Avoid predictable patterns and personal information that could be easily guessed. To further enhance security, the policy should include timeouts on false attempts and locking accounts after a set number of failed login attempt and password expiration policies should be enforced to require users to change periodically ideally every 90 days. Example of strong password P@m1y2Ds$hz!ne%c Why This Password is...

  Data Controller Notification Requirements (UK vs US): In the UK, data controllers must notify their data subjects of data security breaches that pose a high risk to individuals' rights and freedoms, according to the General Data Protection Regulation (GDPR). Notification should occur "without undue delay" and, where feasible, within 72 hours of the breach being discovered. In the US, there is no single federal law mandating data breach notification. Instead, notification requirements vary by state, with different laws governing when and how individuals must be notified of breaches.   The Largest Data Breach of the 21st Century: The largest data breach occurred with Yahoo in August 2013, which was discovered and publicly disclosed in December 2016. Data breach details include: Number of Records Stolen : 3 billion user accounts Type of Data Exposed : Usernames, email addresses, hashed passwords, and security questions and answers Method of Atta...
