Patent number: 11683189Abstract: With the popularity of Blockchain comes grave security-related concerns. Achieving privacy and traceability simultaneously remains an open question. Efforts have been made to address the issues, while they may subject to specific scenarios. The present disclosure proposes a method, a system, and a device for maintaining privacy and traceability of a Blockchain-based system. The method includes: registering in a Blockchain-based system; transmitting a message from a transmitter T to a receiver R via an anonymous network, after a registration request of the transmitter T has been approved and storing message transmission data generated during a message transmission process in a Blockchain; and performing an identity disclosure by using the message transmission data when the message is detected to be false. The anonymous network may transmit the message by onion routing. The solution proposed by the present disclosure can achieve traceability and privacy for a Blockchain-based system simultaneously.Type: GrantFiled: March 19, 2020Date of Patent: June 20, 2023Assignee: Jinan UniversityInventors: Jian Weng, Yue Zhang, Jiasi Weng, Ming Li, Weiqi Luo

Patent number: 11599437Abstract: A mechanism is provided for automatically detecting, diagnosing, transporting, and repairing devices having failed during burn-in testing. Embodiments provide a system that monitors devices undergoing burn-in testing and detecting when a device or a component within a device fails the burn-in test. Embodiments can then alert burn-in-rack monitor personnel of the device failure. Embodiments can concurrently determine the nature of the failure applying a machine learning-based prediction model against log files associated with the failed device. The diagnosis along with a recommended repair strategy can be provided to the repair center as an aid in accelerating the repair process. In addition, the diagnosis can be used to order parts for the repair from a parts depot. In this manner, embodiments can reduce the time for detection, diagnosis, and repair of the failed device.Type: GrantFiled: February 22, 2021Date of Patent: March 7, 2023Assignee: Dell Products L.P.Inventors: Yun Xi, Yu Huang Lin, Meng Meng Jiang, Wen Sen Que, Hua Shan Liang, Mu Shou Lan, Zhi Jian Weng, Lang Lin

Patent number: 11223487Abstract: A method of digital forensics based on blockchain technology and a fine-grained access control scheme, using a finite state machine (FSM) based on smart contracts to manage a digital certificate, where a law enforcement agency ends the warrant request to a court and upon approval of the request collects the forensics data by obtaining the master secret key for accessing the forensic data from a plurality of authorities. The forensics data are encrypted by D-KP-ABE (Distributed Key Police Attribute-based Encryption) with privacy-preserved access policy. The secret sharings are required to form the decryption key for accessing the forensics data. The secret sharings are distributed among the plurality of authorized authorities so that no individual authority has a complete master key by itself. Each state of the FSM requires digital signature(s) of at least one specific authorized authority for transitioning to a next state.Type: GrantFiled: March 19, 2020Date of Patent: January 11, 2022Assignee: Jinan UniversityInventors: Jian Weng, Ming Li, Jiasi Weng, Yue Zhang, Anjia Yang, Weiqi Luo
