Optimal Scheduling of Identity Verification Process on Decentralized Identity Ecosystem

Abstract (in Japanese) (See Japanese page) 
(in English) Several working groups are coping with an ecosystem where a user manages his/her own digital IDinformation among different organizations or companies by decentralized manner. We have also been developing a platform for trustful ID transactions, named IDYX. In the platform, KYC process will be replaced by verifying credentials about users’ information issued by other organizations. The users will no longer need to take procedures for every organization when updating their ID information registered there. However, the KYC policies of companies and relationships among them bring a complicated problem, that is, how to get a better schedule of ID transactions around them. In this paper, we formulate the scheduling problem as an integer linear programming, and propose a heuristic method based on graph structure. Numerical experiments show that the heuristic approach has feasible scalability for practical use.
