ABSTRACT:
Apparatus and methods for computer file management including components and steps for distributing to servers a plurality of mixed images that are generated for each of N, where N≧3, sets of distributed information generated by distributing secret information using a threshold secret sharing scheme, the plurality of mixed images being generated by mixing at different mixing ratios an image based on the distributed information with (Ka−1) images, where Ka satisfies 1<Ka<N; transmitting Kb passwords, where Kb satisfies 1<Kb<N, entered by a user, and obtaining from the plurality of servers at least Ka mixed images for each of Kb sets; first restoring the Kb sets of distributed information based on the Ka mixed images that are obtained; and second restoring the secret information using the Kb sets of distributed information that have been restored.
