Patent ID: 8009830

Claim:
A method for securing a transmission of data blocks in a data stream, the method comprising: generating, using a secure data parser, an encryption key for the data stream; encrypting each data block in the data stream with the encryption key; distributing portions of the encryption key into at least two share headers for the data stream; distributing, using the 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 substantially random 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, whereby the encryption key for the data stream is restorable from at least two share headers of the at least two share headers and the data stream is restorable from at least two data shares of the at least two data shares and from the restored encryption key.
