"Improving Data Security for a Hybrid Society: Insights from New Study"
Researchers at the Tokyo University of Science have introduced a new method that can perform computations with encrypted data more quickly and at a lower cost than traditional approaches, while also enhancing security. Society 5.0 is described as a connected society powered by data shared among people and Artificial Intelligence (AI) technologies connected via Internet of Things (IoT) devices. Although this can be advantageous, protecting data privacy for secure processing, transmission, and storage is critical. Currently, Homomorphic Encryption (HE) and secret sharing are two methods used to maintain the privacy of sensitive data while computing it. Professor Keiichi Iwamura and Assistant Professor Ahmad A. Aminuddin of the Tokyo University of Science introduced a new secure computation method in which all computations are performed on a single server without a high computational cost. The system involves a Trusted Third Party (TTP), one computing server, four players who provide the server with secret inputs, and one player who restores the result of the computation. This article continues to discuss the fast and efficient method developed to handle encrypted data in the cloud for Society 5.0.
