National Applied Research Laboratories Assigned Patent

National Applied Research Laboratories, Taipei, Taiwan, has been assigned a patent (11,416,449) developed by Yeh, Lo-Yao, Lu, Peggy Joy, and Hung, Chia-Hsien, Taichung, Taiwan, for a “method of synchronous deletion for distributed storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present invention provides a method of synchronous deletion for distributed storage system. According to the present invention, after a first host accesses one or more first datum, a first data list and a second data list will be created in a blockchain network corresponding to the modification of the data in the first host. Then the first data list and the second data list are used to update a second host. Accordingly, by taking advantages of the indestructibility of the blockchain technology, the existence of the first data list and the second data list will be maintained. Then the second data accessed by the second host will still be consistent even the first host has modified them. In addition, a hardware safety module can be further adopted to ensure the correctness of the execution file in the second host.”

The patent application was filed on July 23, 2020 (16/936,712).
