Data storage arrangement and method for anonymization aware deduplication
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (12346215) developed by Natanzon; Assaf, and Akirav; Shay, Hod Hasharon, Israel, for “data storage arrangement and method for anonymization aware deduplication.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage arrangement includes a memory and a controller, where the controller receives an indication of data to be anonymized. The controller further parses a data element to be stored and generates a copy of one or more data portions to be anonymized. The controller further deletes one or more data portions to be anonymized to generate a modified data element to be stored. The controller further generates a copy of the modified data element to be stored utilizing deduplication. The data storage arrangement thus takes in account data anonymization during deduplication (i.e. an anonymization aware deduplication).”

The patent application was filed on 2023-03-17 (18/185826).

Direct write strategy for storage system, data processing method, apparatus, node, and storage medium
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (12346589) developed by Luo; Siwei, Wang; Feng, and He; Yi, Chengdu, China, for “direct write strategy for a storage system, data processing method, apparatus, node, and storage medium.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “This application discloses a storage system, a data processing method, an apparatus, a node, and a storage medium, and pertains to the field of data storage technologies. In the method, a client determines an address that is in a storage unit and that is used to store to-be-written data, and sends the to-be-written data to a first storage device that is in a storage node and that is corresponding to the storage unit, so that the first storage device stores the to-be-written data while a CPU of the storage node does not need to determine a hard disk LBA corresponding to virtual address space, and a hard disk does not need to determine a corresponding physical address based on the hard disk LBA.”

The patent application was filed on 2022-09-23 (17/934699).

Append-only data access method and apparatus
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (12340114) developed by Chen; Yu, and Qin; Zhong, Chengdu, China, for “append-only data access method and apparatus.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “This application discloses a data access method and apparatus, and relates to the storage field. In this application, a write request is received; a destination address of a memory area corresponding to to-be-written data is obtained based on address indication information included in the write request; and the to-be-written data is written, in an append write manner, into the memory area indicated by the destination address. After the to-be-written data is written into the memory area, a read/write attribute corresponding to the destination address is set, so that data in the memory area cannot be modified, thereby effectively avoiding illegal tampering with the data stored in the memory area, and implementing read-only protection on data in a storage class memory (SCM) medium.”

If first hash value is not found in ledger, creating set of confirmation data, encrypting new data block with block-unique encryption key, and storing first ownership record in ledger. If first hash value is found in ledger, obtaining information about second host that has already stored previous block identical to new data block, entering in ledger key request, receiving from ledger key transfer record, sending to ledger new ownership record.”
