Cleversafe Assigned Four Patents

Securing data in dispersed storage network using security sentinel value
Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,601,259) developed by Jason K. Resch, Chicago, IL, for “securing data in a dispersed storage network using security sentinel value.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A sentinel value is combined with a data segment, and encrypted. A digest of the encrypted combined data segment is calculated, and used in conjunction with an encryption key to generate a masked key. This masked key is then appended to the encrypted combined data segment and transmitted to an encoder. When the data segment is retrieved, the original encryption key can be recovered and used to decrypt the data segment. The sentinel value can then be extracted from the data segment and checked for integrity. The data segment can then be delivered, discarded, flagged, or otherwise handled based on the integrity of the sentinel value.”

The patent application was filed on April 14, 2010 (12/760,066).

Computing device booting utilizing dispersed storage
Cleversafe, Chicago, IL, has been assigned a patent (8,578,147) developed by Gary W. Grube, Barrington Hills, Ill., and Timothy W. Markison, Mesa, AZ, for a “computing device booting utilizing dispersed storage.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A computing device boot-up method begins by a processing module detecting a boot-up of the computing device. The method continues with the processing module addressing a distributed basic input/output system (BIOS) memory to retrieve a plurality of error coded BIOS data slices. The method continues with the processing module reconstructing BIOS data from the plurality of error coded BIOS data slices using an error coding dispersal function. The method continues with the computing device booting up in accordance with the BIOS data. ”

The patent application was filed on Oct. 5, 2012 (13/645,703).

Storage and retrieval of required slices in dispersed storage network
Cleversafe, Chicago, IL, has been assigned a patent (8,566,354) developed by Gary W. Grube, Barrington Hills, IL, and Timothy W. Markison, Mesa, AZ, for a “storage and retrieval of required slices in a dispersed storage network.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a processing module determining whether one or more encoded data slices of a set of encoded data slices of a plurality of sets of encoded data slices are required encoded data slices to produce one or more required encoded data slices. When the one or more of the encoded data slices are required, the method continues with the processing module generating specific dispersed storage network (DSN) storage information for each of the one or more required encoded data slices, generating general DSN storage information for remaining encoded data slices of the set of encoded data slices, and sending the set of encoded data slices to a dispersed storage network in accordance with the specific DSN storage information and the general DSN storage information. ”

The patent application was filed on Feb. 4, 2011 (13/021,537).

Router assisted dispersed storage network
Cleversafe, Chicago, IL, has been assigned a patent (8,572,282) developed by Gary W. Grube, Barrington Hills, IL, and Timothy W. Markison, Mesa, AZ, for a “router assisted dispersed storage network method and apparatus.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method begins by a router receiving a data packet and determining a destination of the data packet. The method continues with the router determining whether the router has an affiliation with the destination. The method continues with the router determining whether to temporarily locally store the data packet when the router has the affiliation with the destination. The method continues with the router locally storing the data packet and forwarding the data packet to the destination in accordance with a transfer protocol when the determination to temporarily locally store the data packet is favorable.”

The patent application was filed on Aug. 4, 2010 (12/850,611).
