Abstract:
A system for electronically transferring a secure document across a network to a client computer, the secure document formed of a plurality of data blocks, comprising:a. an electronic document server connected to the network, the document server including a server storage device in electronic communication with a processor;b. an encryption module operatively connected to the processor whereby each data block of the secure document can be stored on the server storage device in encrypted form;c. an encryption key generator for generating encryption keys associated with each of the data blocks, using an encryption algorithm;d. a document manager operatively associated with the document server and the client computer such that a user of the system can cause the document server to transfer data blocks selected by the user from the secure document to the client computer in encrypted form, the data blocks selected by the user for transfer to the client computer comprising only a section of the secure document; ande. a decryption module operatively connected to the client computer for decrypting the selected data blocks using the encryption keys.
