Secure data parser method and system
First Claim
Patent Images
1. A system for securing a transmission of data blocks in a data stream, the system comprising a processor configured to:
- encrypt each data block in the data stream with an encryption key;
distribute portions of the encryption key into at least two share headers for the data stream;
distribute data units from the encrypted data blocks into at least two data shares, wherein each of the at least two data shares respectfully contains a distribution of a respective subset of the data units; and
transmit the at least two data shares and the at least two share headers to a remote location over at least one communications path, wherein the at least two share headers are transmitted independently from the at least two data shares.

Abstract
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.

20. A non-transitory computer readable medium having stored therein instructions for, upon execution, causing a processor to implement a method for securing a transmission of data blocks in a data stream, the method comprising:
-
encrypting each data block in the data stream with an encryption key; distributing portions of the encryption key into at least two share headers for the data stream; distributing, using a secure data parser, data units from the encrypted data blocks into at least two data shares, wherein each of the at least two data shares respectfully contains a distribution of a respective subset of the data units; and transmitting the at least two data shares and the at least two share headers to a remote location over at least one communications path, wherein the at least two share headers are transmitted independently from the at least two data shares. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
