Abstract

Finger vein recognition, a promising biometric modality offering low cost and high-resolution vein patterns, faces significant security challenges hindering its widespread adoption. Moreover, the irreplaceable nature of compromised biometric data poses serious threats. This research presents a template protection method, named Random Block Histogram Transformation (RBHT), integrated with multi-instance finger veins. It is used for feature transformation to achieve cancellable biometrics. The method incorporates a modified Histogram of Oriented Gradients (HOG) feature extraction that uses random blocks and Bloom filter for template protection. HOG, which originally uses a grid of blocks with fixed positions and sizes, is modified to use a fixed number of blocks with randomly generated positions and sizes. The random blocks provide unlinkability by allowing a diverse set of biometric templates to be extracted from the same source, making it difficult for attackers to link templates across different applications or systems. Next, Bloom filter is adopted to provide non-invertibility by creating a many-to-one mapping between the feature and template. This prevents the reconstruction of the original biometric data from the template, as an attacker cannot determine which of the many possible inputs were used to generate the template. Finally, efficient hamming distance is utilized for template matching, ensuring high recognition accuracy while maintaining computational efficiency.
