Patent number: 11934549Abstract: One or more implementations of the present specification provide an invoice access method and apparatus based on a blockchain, and an electronic device. The method includes: generating first ciphertext data by encrypting plaintext data of the target invoice based on a first key corresponding to an invoice issuer; generating second ciphertext data by encrypting the plaintext data of the target invoice based on a second key corresponding to an invoice receiver; adding the first ciphertext data and an user identifier of the invoice issuer to the blockchain as related to one another; and adding the second ciphertext data and an user identifier of the invoice receiver to the blockchain as related to one another.Type: GrantFiled: August 31, 2021Date of Patent: March 19, 2024Assignee: Advance New Technologies Co., Ltd.Inventors: Hansong Xiao, Ping Zhang, Wenhu Kan, Qin Liu, Liangrong Lin, Fuxi Deng, Yixiang Zhang, Rui Chen, Jinming Duan

Publication number: 20230238023Abstract: Various apparatuses, systems, methods, and media are disclosed to provide a heat-assisted magnetic recording (HAMR) medium that has a media carbon dual-layer media carbon overcoat with both a carbon layer and a carbon-nitrogen (CN) layer. The carbon layer may be a plasma enhanced chemical vapor deposition (PECVD) carbon layer and the CN layer may be a sputtered CN layer. The dual-layer media carbon overcoat helps reduce a laser power requirement of an HAMR disk drive system and thus reduce the operating temperature of a near field transducer (NFT) of a HAMR disk drive. The dual-layer overcoat can also improve thermal and thermo-oxidative stability of the media and help retain a lubricant provided on the overcoat, therefore improving HAMR head-media interface reliability. The dual-layer media carbon overcoat can also reduce carbonaceous smear within a head-media gap.Type: ApplicationFiled: January 5, 2023Publication date: July 27, 2023Inventors: Tan Duy Trinh, Yixiang Zhang, Sukumar Rajauria, Erhard Schreck, Qing Dai, Paul Christopher Dorsey

Patent number: 11425108Abstract: Blockchain-based service data encryption methods and apparatuses are provided wherein by a first derived key is obtained by a node device of a key receiver, the first derived key distributed by a node device of a key distributor, wherein the first derived key is derived from a derived key of the key distributor based on a service data permission type of the key receiver and service data is encrypted based on the first derived key to obtain encrypted service data. The encrypted service data is sent to a blockchain, so that the encrypted service data is recorded in a distributed database of the blockchain after the blockchain performs consensus verification on the encrypted service. Because the derived key of the key distributor can decrypt the service data encrypted by the first derived key, the key distributor can decrypt, monitor, and manage service data uploaded by the key receiver.Type: GrantFiled: August 18, 2021Date of Patent: August 23, 2022Assignee: Advanced New Technologies Co., Ltd.Inventors: Shubo Li, Yixiang Zhang
