Patent number: 12159230Abstract: An example system and method facilitate enabling precise answers to technical support questions pertaining to a given computing environment, e.g., a cloud-based enterprise computing environment. The example method includes using an overtrained recurrent neural network employing Long Short-Term Memory (LSTM) cells to selectively answer specific questions by providing precise answers to technical support questions. A second neural network that is not overtrained can provide more generalized answers when a confidence measurement of an answer of the first neural network falls below a predetermined threshold. Furthermore, expert staff, e.g., developers and/or engineers that may be able to more precisely answer a specific question may be shown the answer. Subsequent expert answers or modifications to existing answers may be used to further refine the neural networks, e.g., via periodic supervised learning.Type: GrantFiled: August 7, 2018Date of Patent: December 3, 2024Assignee: Oracle International CorporationInventors: Wenchao Sun, Zhengrong Liu

Patent number: 7716494Abstract: A trusted platform in a digital processing system is maintained even when modules, or other processes or data, are loaded after a boot sequence. A configuration file is used to include measurements (e.g., hash values, signatures, etc.) of modules to be loaded. After secure boot-up the operating system kernel uses the configuration file to check module integrity prior to loading and executing. If a module does not verify against the configuration file data then the system can prevent further operation, restrict certain operations, indicate the non-trusted nature of the system or take other actions. In one embodiment, if a module does not pass the integrity check then the failed measurement is extended into a specific Platform Configuration Register (PCR) within a Trusted Platform Manager (TPM) process. Subsequently, client applications can determine if the platform is trustable based on the return of the PCR value.Type: GrantFiled: July 15, 2004Date of Patent: May 11, 2010Assignees: Sony Corporation, Sony Electronics, Inc.Inventors: Zhengrong Liu, Yusuf Wilajati Purna, Takemura Shinichi, Nicholas Szeto

Patent number: 7552326Abstract: A system to manage and control usage rights for cryptographic keys. A kernel process is provided with secure and exclusive authorization to access certain keys in a key hierarchy. Special authorization is required for other processes or users to access keys used by the kernel. A persistent storage area is used to hold a Kernel Authorization Data field for the root key and/or other keys used by the kernel or other specialized processes. The authorization data, and the keys it protects, can be used to protect other portions of, or the entire, key structure. The persistent storage area is reserved in a TPM or similar security hardware.Type: GrantFiled: July 15, 2004Date of Patent: June 23, 2009Assignees: Sony Corporation, Sony Electronics, Inc.Inventors: Zhengrong Liu, Harold Aaron Ludtke, Ikuo Shinozaki
