Abstract
A user using a client computer registers with a server computer over a computer network by submitting a biometric scan of a body part of the user. The user commands the client computer to encrypt an electronic file. The client computer generates a private key, encrypts the electronic file and transmits the key to the server computer. The client computer saves the encrypted file. The encrypted file and the key are saved at different physical locations. The owner of the file is able to grant permission to other registered users to unlock the encrypted file.
