As cloud-based data has grown increasingly prevalent, data protection has become a critical issue, and homomorphic encryption, which allows mathematical processes to be performed on data in its encrypted state, has gained attention. Existing homomorphic encryption methods, however, use bit -by-bit encryption, which slows down processing times, making practical application of it problematic.
This technology makes it possible to use cloud-based data in more ways while safeguarding privacy. For example, when applied to biometric authentication, such as a fingerprint or vein data, this technology makes it possible to securely match encrypted data without having to decrypt it. Using confidential information such as medical or biological data for data analysis has, up until now, been problematic from a privacy standpoint.
Details of this technology are being presented at the
The increasing prevalence of cloud-based data and mobile devices has led to the emergence of a number of new information services to meet people's needs. At the same time, there is an increasing awareness of the problem of personal information becoming public and of the need to be able to use personal data while keeping it private.
Encryption is an effective way to protect data, although in most encryption methods, data needs to be temporarily decrypted in order to perform calculations such as totals. This is problematic because the data becomes vulnerable the moment it is decrypted. Homomorphic encryption, however, allows for calculations to be performed on data in an encrypted state, making it a promising technology for delivering new cloud services.
