Secure data parser method and system

摘要

A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

主权项

1. A method performed by a computer system for securing a first data set while providing recoverability of the first data set in the event of unavailability of data at one or more storage locations, the method comprising:
(a) reading the first data set from a memory that stores the first data set, (b) processing the first data set to produce a second data set, the processing comprising:
encrypting the first data set using an encryption key to produce an encrypted data set, andlogically combining at least a portion of the encrypted data set with the encryption key to produce a resultant, wherein the second data set comprises the encrypted data set and the resultant, and wherein all of the at least a portion of the encrypted data set is required to recover the encryption key based on the resultant; (c) producing redundancy information based on information in the second data set; (d) producing a plurality of n shares from the second data set, wherein each of the n shares comprises at least some of the second data set; and (e) storing the plurality of n shares and the redundancy information, wherein at least some of the n shares are stored in separate storage locations and the first data set is recoverable using at least a threshold number, less than n, of the plurality of n shares.
