Massachusetts Institute of Technology (MIT), Cambridge, MA, has been assigned a patent (11,025,600) developed by Medard, Muriel, Belmont, MA, Moorthy, Prakash Narayana, Framingham, MA, and Abdrashitov, Vitaly, Somerville, MA, for “system for de-duplicating network coded distributed storage and related techniques.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Methods for encoding a file and de-duplicating a coded packet of the file are presented. The encoding method includes: identifying a file to be stored, encoding the file to generate a plurality of coded packets, generating a hash code associated with the file, distributing the plurality of coded packets to a plurality of storage nodes, and storing the hash code associated with the file in a hash server. The de-duplicating method includes: receiving a coded packet at a storage node, retrieving a hash code, from the hash server, corresponding to the coded packet, determining whether the coded packet has been stored in the storage node based upon the hash code, in response to determination that the coded packet has being stored, discarding the coded packet, and in response to determination that the coded packet has not being stored, storing the coded packet in the storage node.”

The patent application was filed on November 8, 2018 (Appl. No.16/184,272).
