| Abstract(in English) | n this paper, we propose Gaussian Process Regression (GPR) for encrypted data generated based on random unitary transformation (RUT) and evaluate its performance. In recent years, computational forms that utilize computational resources provided by providers using edge and cloud services have rapidly become widespread. However, there are concerns about problems such as data fraud, leakage, and privacy invasion due to lack of reliability of providers and accidents. This paper examines the secure Gaussian process regression method that takes privacy protection into consideration. It is possible to solve the Gaussian process regression problem by encrypting not only the input signal but also the output signal. It is shown that the prediction performance does not deteriorate as compared with the case without encryption. Finally, as an application example of the secure Gaussian process regression, the disease progression is predicted using clinical data of diabetes, and the effectiveness of the proposed method is verified by simulation. |
