Patent number: 11917130Abstract: A video coding mechanism for viewpoint dependent video coding is disclosed. The mechanism includes receiving a spherical video signal stitched from multiple directional video streams. The spherical video signal is mapped into a plurality of sub-picture video signals each containing a sequence of sub-pictures. The plurality of sub-picture video signals, are encoded as a plurality of sub-picture bitstreams, such that, when decoded at a decoder, a value of each sample in each sub-picture is identical to a value of a corresponding sample in a decoded entire picture composed from the sub-pictures. The plurality of sub-picture bitstreams are composed into a plurality of sub-picture tracks with an indication that the sub-picture tracks are conforming to a particular video profile. The sub-picture bitstreams are transmitted toward a decoder to support decoding and displaying virtual reality video viewport.Type: GrantFiled: July 5, 2022Date of Patent: February 27, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Ye-Kui Wang, Huameng Fang, Yuqun Fan, Jianle Chen

Patent number: 10922684Abstract: Optimizations are provided for completing a transaction event using authentication information. In particular, a presence of a transaction processing device is initially detected. Then, transaction information is received from the transaction processing device. The transaction information corresponds to a current transaction event. After receiving the information, a communication link is established with an on-body device. This device includes authentication information that is necessary to complete the current transaction event. The authentication information is then received from the on-body device. This information has a time-limited use availability. Finally, the received authentication information is used to complete the current transaction event.Type: GrantFiled: September 29, 2017Date of Patent: February 16, 2021Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Yuqun Chen, Gideon A.

Patent number: 8146138Abstract: A plurality of access units may be established with varying levels of privilege and access rights, such that the user may perform tasks carrying with them a high risk of viral infection in an access unit with a low level of privilege and access rights. When an authenticated user desires to perform tasks requiring a higher level of privilege and access rights, the user may switch to an access unit having a higher privilege and access rights level by instigating a physical action. The physical action may include selecting a button (included in either a UI or on a peripheral device), or inputting biometric data to switch among running access units. A signal instigated by the physical action is transmitted along a trusted path between the isolation kernel and where the physical action was instigated.Type: GrantFiled: December 15, 2005Date of Patent: March 27, 2012Assignee: Microsoft CorporationInventors: Yuqun Chen, Marcus Peinado

Patent number: 7975117Abstract: Plural guest operating systems run on a computer, where a security kernel enforces a policy of isolation among the guest operating systems. An exclusion vector defines a set of pages that cannot be accessed by direct memory access (DMA) devices. The security kernel enforces an isolation policy by causing certain pages to be excluded from direct access. Thus, device drivers in guest operating systems are permitted to control DMA devices directly without virtualization of those devices, while each guest is prevented from using DMA devices to access pages that the guest is not permitted to access under the policy.Type: GrantFiled: December 19, 2003Date of Patent: July 5, 2011Assignee: Microsoft CorporationInventors: Marcus Peinado, Paul England, Bryan Mark Willman, Yuqun Chen, Andrew John Thornton

Patent number: 7957532Abstract: A network-based data protection scheme for a mobile device utilizes encryption techniques and a remote key server that stores encryption keys on behalf of the mobile device. The mobile device stores encrypted data, preferably having no unencrypted counterpart stored therewith. On an as-needed basis, the mobile device requests a decryption key (or an encrypted version of a decryption key) from the key server, where the decryption key can be used by the mobile device to decrypt the encrypted information. The key server transmits the decryption key to the mobile device after authenticating the user of the mobile device.Type: GrantFiled: June 23, 2006Date of Patent: June 7, 2011Assignee: Microsoft CorporationInventors: Yuqun Chen, Zicheng Liu, Mariusz H.
