ABSTRACT
The preservation of data privacy is paramount in today's digital landscape, where data collection and storage are routine practices. Traditional unique identifiers pose inherent risks, as they can be manipulated or exploited by attackers, compromising the privacy of individuals' data. To mitigate these risks, this paper proposes a novel approach combining biometric authentication through palm vein recognition with a pseudonym system. This system anonymizes data records, safeguarding sensitive information from unauthorized access. By employing techniques such as Gaussian and median filtering, CLAHE filtering, Canny edge detection, and Harris key point extraction, alongside cryptographic methods including HMAC-SHA256 and SHA3-512, data privacy is enhanced significantly. Comparison between the two cryptographic algorithms reveals that SHA3-512 offers superior security and robustness compared to SHA256. Through this innovative framework, users can ensure their data remains protected, with their true identities concealed from prying eyes, thereby addressing critical privacy concerns in digital data storage and transmission.
