Biometric based Copyright Verification in the Era of Digital Piracy : A Promising Solution

In an era of technological progress and pervasive digitalization across various sectors, the necessity for information security has risen to the forefront. In this digital age, the copyright verification stands out as a critical method for ensuring information security. In this paper, a promising solution for copyright verification is proposed, integrating the trustworthiness of biometric technologies with the power of chaos. In this study, we introduce a novel approach where features are first extracted, encoded, and encrypted before being seamlessly integrated into the cover image using the SM2LSB-based watermarking tech-nique. A notable advantage of our method is the compact size of the encoded feature vector, which effectively reduces distortions in the cover image. Notably, our system optimizes the parameters of the chaos system to identify the most optimal embedding locations, further enhancing the method’s efficacy. The results obtained using the PolyU MSP database, comprising 300 persons, clearly demonstrate that our scheme outperforms several existing methods with a higher identification rate and substantially reduced distortion ratio.
