Efficient implementation of optical scanning holography in cancelable biometrics

Area of Science:

• Biometric Security Systems
• Cybersecurity
• Information Security

Background:

• Traditional single-biometric systems are vulnerable to attacks and permanent data loss.
• Biometric signatures can be compromised indefinitely in hacking scenarios.
• Cancelable biometrics offers a solution by using deformed or encrypted biometric versions.

Purpose of the Study:

• To propose a novel cancelable multi-biometric system.
• To enhance security and privacy in biometric identification.
• To create a unified, secure biometric template from multiple traits.

Main Methods:

• Utilizing optical scanning holography (OSH) for biometric acquisition.
• Applying discrete cosine transform (DCT) for simultaneous compression and template generation.
• Combining multiple biometric traits into a single cancelable template.

Main Results:

• The proposed method generates a unified cancelable biometric template.
• The system enhances security by using multiple biometrics.
• Simulation results demonstrate robustness in noisy environments.

Conclusions:

• The OSH-based cancelable multi-biometric approach offers improved security and privacy.
• This method provides a robust solution for biometric verification.
• The unified template is resilient against attacks and data loss.
