Abstract: A provider system is connected to readers disposed at distances from the provider system. A secure local connection is established between the client device and the provider system via one of the readers. Before the client reaches an access touchpoint, the provider system receives from the client device a request for client access, the provider system sends to the client device a request for identification information of the client, and the client device sends client information associated with a first mobile identification credential (MIC) which the client device received from an authorizing party system (APS), the client having consented to release the client information to the provider system, and the client information having been verified. The provider system uses the verified client information associated with the first MIC to verify or not verify the identity of the client before granting or denying the request to the client.

Abstract: Disclosed herein are a method, an apparatus, and a storage medium for image encoding/decoding using partitioning. Various prediction methods and prediction modes may be used for prediction of a block. When a block is partitioned, information related to partitioning, such as information indicating whether partitioning is to be performed and information specifying the type of partitioning, is signaled. Also, when partitioning is applied to the block, an available prediction method and an available prediction method in prediction for the block may be restricted in prediction for the block. For optimization of signaling, multiple pieces of information related to prediction may be signaled, wherein the pieces of information may have dependency relationships, and in some cases, additional information may be derived as specific values depending on the value of one piece of information, and signaling of the additional information may be skipped.
