Abstract
In an access management system for managing access to data handled on a shared server, the data in a registered folder on the shared server is kept in secret through transform using an access key. A database in the system is configured to store identification information of n shares generated by splitting the access key using threshold secret sharing scheme in association with a data path of a folder assigned to a first user. Some of the shares are retained in the system as system shares and at least one remaining share is provided to the first user as a user share. When an access request is received along with a first user share from the first user, target data recovered using the access key recovered based on a number of shares that satisfies the quorum is deployed to the registered folder.
