NEC Corp., Tokyo, Japan, has been assigned a patent (11853437) developed by Bohli, Jens-Matthias, Karame, Ghassan, and Armknecht, Frederik, Heidelberg, Germany, for a “method for storing data on a storage entity.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for storing data on a storage entity (SE) includes: computing a file identifier for a file to be stored on the SE, checking if the file has already been stored using the file identifier, generating a user-specific private and public identifier, wherein generating the user-specific private identifier is based on using an oblivious key generation protocol between the client and a trusted entity, and wherein the user-specific private identifier is a deterministic private identifier, updating or computing tags of the file by the client such that the updating or computing is homomorphic in the user-specific private identifier and in parts of the file, and providing the user-specific public identifier, the updated tags and a proof of possession of the secret identifier to the SE to enable the SE to store information associated with the file.”

The patent application was filed on 2021-05-20 (17/325230).
