Abstract

In the modern tech world, biometric authentication technologies have become more and more common in a number of sectors, including mobile devices, banking, healthcare, and border control. However, there are serious security and privacy risks associated with the increasing reliance on biometric data. This is because biometric data is computed in raw formats on third-party cloud servers, creating privacy hazards as well as possibilities of illegal access to sensitive personal information. This paper explores the use of homomorphic encryption (HE) to safeguard user privacy and facilitate cloud-based computations on biometric data. Since cloud-based biometric authentication is becoming popular, it is necessary to handle this sensitive data securely. This study bridges the gap by designing a tailored HE algorithm that is perfect for biometric computations on cloud platforms. To find out how well our strategy maintains accuracy and privacy, we will compare it with other existing approaches. The primary feature of this encryption is that any kind of computation can be performed on encrypted data without changing its original format. The expected result is an observably secure and effective HE-based system for biometric calculations in the cloud, which will promote a wider usage of cloud authentication that preserves privacy.
