<heading>Secure Medical Data Management Based on Homomorphic Encryption and Secret Sharing</heading></a>
<br>
We propose a cloud storage system that utilizes homomorphic encryption and secret sharing. Our approach enables secure cloud storage of medical data and allows secure data sharing without harming patients’ privacy. A proof-of-concept implementation demonstrates the feasibility of the storage system.

<heading>Taylor Polynomial Enhancer using Genetic Programming for Symbolic Regression</heading></a>
<br>
We propose using genetic programming as a Taylor polynomial enhancer, namely TPE-GP, to combine the advantages from TP and GP. Specifically, TPE-GP utilizes infinite-order operators to compensate the power of TP with finite order.

<heading>Earthquakes Cluster Applied Ricci Curvature</heading></a>
<br>
It’s important to observe earthquake distribution and source properties. In this project, Ricci curvature was used to record and classify earthquakes to know the regional properties. Based on the comparative analysis, the result using Ricci curvature is better than that of Kmeans clustering.
