Abstract

The present invention provides a method and system for securing sensitive data from unauthorized access or use. The method and system of the present invention is useful in a wide variety of settings, including commercial settings generally available to the public which may be extremely large or small with respect to the number of users. The method and system of the present invention is also useful in a more private setting, such as with a corporation or governmental agency, as well as between corporation, governmental agencies or any other entity.

Claims

1. (canceled)

2. A method performed by a computer system for securing a data set, the method comprising:

(a) producing redundancy information based on information in the data set;

(b) producing a plurality of n shares using the data set, each of the n shares comprising at least some of the data in the data set;

(c) including at least some of the redundancy information in each of the plurality of n shares; and

(d) using a computer network coupled to the computer system to substantially randomly distribute at least some of the plurality of n shares to a corresponding plurality of physically dispersed storage locations;

wherein the data set is recoverable using at least a threshold number, less than n, of the n shares.

3. The method of claim 2 further comprising providing an encryption key for use in encrypting the data set to form an encrypted data set, wherein producing the plurality of n shares from the data set comprises producing the plurality of n shares from the encrypted data set.

4. The method of claim 2, wherein at least some of the plurality of dispersed storage locations are geographically remote from one another.

5. The method of claim 2, wherein the plurality of dispersed storage locations are associated with different internet protocol (“

IP”

) addresses.

6. The method of claim 2, wherein producing the plurality of n shares comprises causing the n shares to comprise a substantially random distribution of units of data of the data set.

7. The method of claim 2, wherein producing the plurality of n shares comprises substantially randomly distributing units of data of the data set into the plurality of n shares.

8. The method of claim 2, wherein producing the plurality of n shares comprises distributing units of data of the data set into the plurality of n shares and substantially randomly shuffling the units of data in the shares.

9. The method of claim 3, wherein the data set is encrypted by a server.

10. The method of claim 3, wherein the data set is encrypted by a client device.

11. The method of claim 2, wherein producing the plurality of n shares is performed by a server.

12. A system configured for securing a data set, the system comprising:

one or more processors configured to;

(a) produce redundancy information based on information in the data set;

(b) produce a plurality of n shares using the data set, wherein each of the n shares comprises at least some of the data set;

(c) include at least some of the redundancy information in each of the plurality of n shares; and

(d) substantially randomly distribute at least some of the plurality of n shares to a corresponding plurality of physically dispersed storage locations, wherein the data set is recoverable using at least a threshold number, less than n, of the n shares.

13. The system of claim 12, wherein the one or more processors is further configured to provide an encryption key for use in encrypting the data set to form an encrypted data set, and wherein the one or more processors is further configured to produce the plurality of n shares from the data set by producing the plurality of n shares from the encrypted data set.
