Publication number: 20240153219Abstract: A computer system displays a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras. The computer system receives a request to add a first virtual effect to the displayed representation of the field of view of the one or more cameras. In response to receiving the request to add the first virtual effect to the displayed representation of the field of view of the one or more cameras and in accordance with a determination that the first virtual effect requires a scan of the physical environment, the computer system initiates a scan of the physical environment to detect one or more features of the physical environment and displays a user interface that indicates a progress of the scan of the physical environment.Type: ApplicationFiled: January 12, 2024Publication date: May 9, 2024Inventors: James A.

Patent number: 11979494Abstract: The disclosed exemplary embodiments include computer-implemented systems, devices, and processes that securely manage and regenerate cryptographic keys using permissioned distributed ledgers. For example, a device may receive, from a first computing system, data indicative of a recordation of a first public key onto a distributed ledger. Based on an occurrence of a regeneration condition, the device may transmit, to a second computing system, a second public key and a first digital signature, and the second computing system may validate the first digital signature, apply a second digital signature to the second public key, and transmit the second public key and the digital signatures to the first computing system. The device also receives, from the first computing system, additional data indicative of a recordation of the second public key onto the distributed ledger, and based on the additional data, the device may invalidate the first private key.Type: GrantFiled: April 13, 2022Date of Patent: May 7, 2024Assignee: The Toronto-Dominion BankInventors: Alexey Shpurov, Albert Louis Rothenstein, Adrian Chung-Hey Ma, Buturab Rizvi, Alexandra Tsourkis, Francis James Alexander Guttridge
