Title: "IrisCodeShield: A Novel Template Protection Approach for Iris Recognition"

Abstract:

Iris recognition has become a widely used biometric modality for identity verification and authentication. However, the storage and transmission of iris templates pose significant security risks, as they can be easily stolen or tampered with. To address this issue, we propose a novel template protection approach, IrisCodeShield, which leverages advanced cryptographic techniques and machine learning algorithms to securely store and protect iris templates. Our approach ensures the confidentiality, integrity, and authenticity of iris templates, while maintaining the accuracy and efficiency of iris recognition systems.

Introduction:

Iris recognition has gained popularity in various applications, including border control, law enforcement, and identity verification. However, the storage and transmission of iris templates pose significant security risks, as they can be easily stolen or tampered with. This is because iris templates are typically stored in plaintext, making them vulnerable to attacks such as template theft, tampering, and replay attacks.

Background:

Several template protection approaches have been proposed to address the security risks associated with iris recognition. These approaches can be broadly categorized into two types: (1) encryption-based approaches, which encrypt the iris template using symmetric or asymmetric encryption algorithms, and (2) watermarking-based approaches, which embed a watermark into the iris template to detect tampering or unauthorized use.

IrisCodeShield:

Our proposed approach, IrisCodeShield, combines the benefits of encryption and watermarking to provide a robust template protection mechanism. The approach consists of three main components:

  1. IrisCode Generation: We generate a unique IrisCode for each iris template using a machine learning-based algorithm. The IrisCode is a compact representation of the iris template that captures its essential features.
  2. Encryption: We encrypt the IrisCode using a symmetric encryption algorithm, such as AES, to ensure confidentiality and integrity.
  3. Watermarking: We embed a watermark into the encrypted IrisCode to detect tampering or unauthorized use. The watermark is a unique identifier that is linked to the iris template and can be used to verify the authenticity of the template.

Advantages:

IrisCodeShield offers several advantages over existing template protection approaches:

  1. Improved Security: Our approach provides a higher level of security by combining encryption and watermarking, making it more difficult for attackers to steal or tamper with iris templates.
  2. Efficient: IrisCodeShield is designed to be efficient, with a low computational overhead and minimal storage requirements.
  3. Accurate: Our approach maintains the accuracy of iris recognition systems, as the IrisCode is generated using a machine learning-based algorithm that captures the essential features of the iris template.

Conclusion:

In this paper, we propose a novel template protection approach, IrisCodeShield, which combines encryption and watermarking to securely store and protect iris templates. Our approach provides a robust mechanism for protecting iris templates against various security threats, while maintaining the accuracy and efficiency of iris recognition systems. We believe that IrisCodeShield has the potential to revolutionize the field of iris recognition and provide a new standard for template protection in biometric applications.
