Naver and Industry-University Cooperation Foundation Hanyang University Erica Campus Assigned Patent

Naver Corporation, Gyeonggi-do, Korea, and Industry-University Cooperation Foundation Hanyang University Erica Campus, Gyeonggi-do, Korea, has been assigned a patent (11,218,174) developed by Park, Chanyoung, Won, Jiwoong, Ryu, Junhee, Kang, Kyungtae, Ansan-si, Korea, Choo, Yun-cheol, Jun, Sung-Won, Seongnam-si, Korea, and Kim, Taewoong, Seongnam-si, Korea, for “method and system for storing data locally repairable and efficient multiple encoding.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Provided are methods and systems for storing data using locally repairable multiple encoding. A data storage method may include generating n N.times.M encoding matrices, each including an M.times.M first matrix, an 1.times.M second matrix in which all of elements have a value of 1, and an M.times.M third matrix that is a symmetric matrix in which respective columns are configured by changing a sequence of elements from an element set, arranging the encoding matrices into a plurality of groups, generating a data block through the first matrix, a local parity block through the second matrix, and a global parity block through the third matrix by encoding source data of a first group with a first encoding matrix among the encoding matrices arranged into the first group, and merging the global parity block with a global parity block of a second encoding matrix that is different than the first encoding matrix.”

The patent application was filed on October 17, 2019 (16/655,812).
