EFFICIENT AND SECURE DATA STORAGE UTILIZING A DISPERSED DATA STORAGE SYSTEM
First Claim
Patent Images
1. A method operating on a computer, the method comprises:
- applying an all-or-nothing transformation to a data segment to produce an all-or-nothing data segment;
encoding, using an information dispersal algorithm, the all-or-nothing data segment to produce a set of encoded data slices; and
generating a set of write command to write the set of encoded data slices to storage units of a dispersed storage network.

Abstract
A method of securely storing data to a dispersed data storage system is disclosed. A data segment is arranged along the columns or rows of an appropriately sized matrix. Data slices are then created based on either the columns or the rows so that no consecutive data is stored in a data slice. Each data slice is then stored in a separate storage node.

7. A computer comprising:
-
a network port adapted to couple with a network and receive a data segment; and a processor coupled to the network port wherein the processor; applies an all-or-nothing transformation to the data segment to produce an all-or-nothing data segment; encodes, using an information dispersal algorithm, the all-or-nothing data segment to produce a set of encoded data slices; and generates a set of write commands to write the set of encoded data slices to storage nodes of a dispersed storage network. - View Dependent Claims (8, 9, 10, 11)
