Abstract
Official abstract text for this publication.
A distributing device for generating private information correctly even if shared information is destroyed or tampered with. A shared information distributing device for use in a system for managing private information by a secret sharing method, including: segmenting unit that segments private information into a first through an n th pieces of shared information; first distribution unit that distributes the n pieces of shared information to n holding devices on a one-to-one basis; and second distribution unit that distributes the n pieces of shared information to the n holding devices so that each holding device holds an i th piece of shared information distributed by the first distribution unit, as well as a pieces of shared information being different from the i th piece of shared information in ordinal position among n pieces of shared information, “i” being an integer in a range from 1 to n.
