Abstract

See full text

A server receives from a user's computer a request to store a file and a file hash value. The server determines whether a file with the same hash value is stored on the server. If so, the server grants access to the server's file copy. If not, the server requests the user to upload the file and stores it. The server grants access to the copy by sending the user a pointer to the copy's storage location and associating the user with the pointer in a database. The server can challenge the user's right to access the copy by requesting a file password or a portion of the file stored on the user's computer. The server can limit access to the server's copy to users who successfully respond to the challenge.
