Problems solved by technology

However, IoT objects themselves are often less capable and thus vulnerable to adversaries, so they cannot be fully trusted as access verification entities
Therefore, the distributed CapBAC model may not be able to solve the access control problem in an untrusted IoT environment

Embodiment 1

[0049] Such as figure 1 and 2 As shown, the access control method for user information across multiple organizations of the present invention includes the following steps:

[0050] S100, initialize the alliance administrator node, the above-mentioned alliance administrator node is a node on the blockchain network and has a unique account address in the blockchain network;

[0051]S200. Deploy the smart contract configured with the access control policy in the blockchain network through the alliance administrator node;

[0052] S300. For each organization that wants to join the above alliance, select at least one server as its organization owner node, and each organization owner node registers in the above blockchain network to obtain a unique account address. For each organization that wants to join the above alliance Organizations, select at least one server to register on the above-mentioned blockchain network, after registration, each server becomes a server node on the b...

Embodiment 2

[0069] An apparatus of the present invention, comprising: at least one memory and at least one processor;

[0070] The above at least one memory is used to store machine-readable programs;

[0071] The above at least one processor is configured to invoke the machine-readable program to execute the method for access control of user information across multiple organizations disclosed in Embodiment 1.

Embodiment 3

[0073] The medium of the present invention is a computer-readable medium, and computer instructions are stored on the computer-readable medium. When the above computer instructions are executed by the processor, the above-mentioned processor executes the access control of cross-organization user information disclosed in Embodiment 1. method. Specifically, a system or device equipped with a storage medium may be provided, on which a software program code for realizing the functions of any of the above embodiments is stored, and the computer (or CPU or MPU of the system or device) ) to read and execute the program code stored in the storage medium.

Abstract

The invention discloses a cross-multi-organization user information access control method and device and a medium, belongs to the technical field of Internet-of-Things access control, and aims to solve the technical problem of how to realize safe, decentralized and trustless inter-multi-organization user information access. The method comprises the following steps: initializing alliance administrator nodes; deploying the smart contract configured with the access control strategy in a blockchain network through an alliance administrator node; for each organization to join the alliance, selecting at least one server as an organization owner node of the organization, and registering each organization owner node in the blockchain network to obtain a unique account address; storing account addresses related to the organization owner nodes passing the verification into an alliance member list; enabling the organization owner node to share the user information in the organization to the blockchain network; and enabling the organization owner node to send an access request for accessing the user information in other organizations to the alliance administrator node, verifying the access request through the smart contract, and returning the corresponding user information to the organization owner node proposing the access request after the verification is passed.

Description

technical field [0001] The invention relates to the technical field of Internet of Things access control, in particular to a method, device and medium for access control of user information across multiple organizations. Background technique [0002] In the current information age of continuous development and dynamic changes, a wide variety of organizations or institutions in various fields are emerging. With the continuous development of these organizations and institutions and the passage of time, the information of users and resources (such as files, cameras, etc.) contained in the organization will continue to increase. It is inevitable that these users and resources (sensors, smart devices, etc.) If it can be connected to the Internet of Things, the information related to users and resources may be uploaded to the network by their respective organizations, users or devices themselves through the Internet of Things for all other organizations and users to view and use ...
