SUPPORTING TWO PHASE COMMIT PROTOCOL IN BLOCKCHAIN SYSTEM

Resumen de: CN120981828A

The blockchain system is capable of participating in distributed transactions using a two-stage commit protocol ("2PC"). In a 2PC, a computer system, such as a DBMS or blockchain system, submits transactions that change data (e.g., database, world state) using two stages. To participate in a distributed transaction using a 2PC, a blockchain system performs a "staged transaction". The staged transaction passes through a 2PC stage. In the preparation stage, the new value of the world state record is temporarily stored in the stage record as a stage value. In a second stage, if a distributed transaction is to be submitted, a world stage record is set to a stage value.

Resumen de: US20260046134A1

An imaging system provider (110) provides updates to an imaging facility (120). These updates are referred to as configurations, and each configuration has an associated date-time. The provider stores each configuration and its date-time in a blockchain (130). When the imaging facility acquires an image of a patient, the image is watermarked (125) with an identification of the configuration of the imaging system at the time the image was acquired. When the patient (150) wants to verify whether the image was taken 2024/038033 using the most up to date configuration, the patient submits an identification of the image to a verification system (140). The verifier submits a request for proof from the imagining facility. The imaging facility compares the watermarked information and the information in the block chain, and provides the proof to the verification system, which verifies the proof. To assure privacy and security, a zk-SNARK is used for the proving and verification processes.

Resumen de: CN120981807A

Embodiments use credential authentication and user information verification to allow range-limited access of security information to a user. Certain information sharing protocols may require an unambiguous grant to share the user's security information with the requesting entity. In some scenarios, such an explicit grant may be impractical, such as when a user cannot provide such an explicit grant. Embodiments of a security information manager can allow a reviewed entity to range and time limited access to security information of a user in such scenarios, such as when the reviewed entity provides an assertion that the user cannot provide an explicit grant. For example, in one or more scenarios with an emergency situation, the security information manager can allow a reviewed entity to access a limited range of user information corresponding to a relationship of the reviewed entity to a user, a role in a workflow, or other suitable characteristics of the reviewed entity.
