Embodiment Construction

[0041] The present invention is further described in conjunction with the following examples.

[0042] see figure 1 , the embodiment of the first aspect of the present invention provides a cloud service-based information exchange method, the method includes:

[0043] The S1 cloud service platform receives the sensing information obtained from the wireless sensor network. The wireless sensor network includes multiple sensor nodes, multiple cluster heads and a single convergence node. Each sensor node selects the nearest cluster head to join the cluster; each cluster The head receives the sensing information collected and sent by each sensor node in the cluster, and the convergence node communicates with the cluster head through wireless communication, collects the sensing information and transmits it to the cloud service platform.

[0044] The cloud service platform in S2 assigns an access authority level to the sensing information according to the importance level of the sens...

Abstract

The invention provides an information exchange method and system based on a cloud service, The system comprises a cloud service platform, a wireless sensor network and a client computer, and the method comprises the steps that the cloud service platform receives perception information obtained by a wireless sensor network end; The cloud service platform allocates an access permission level to thesensing information according to the importance level of the sensor node corresponding to the sensing information; The cloud service platform stores the perception information in a cloud storage partition corresponding to the access permission level of the cloud service platform; The cloud service platform receives an access request sent by a client computer, wherein the access request comprises an access permission level of the client computer and a cloud storage partition identifier requested to be accessed; And when the access permission level of the client computer exceeds the access permission level corresponding to the cloud storage partition identifier requested to be accessed, the cloud service platform sends the perception information in the corresponding cloud storage partition to the client computer.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an information exchange method and system based on cloud services. Background technique [0002] In related technologies, wireless sensor network technology is used to collect sensing information, and the information is sent to a cloud service platform for storage. In the process of information interaction between the client computer and the cloud service platform, the perceived information is easily tampered and peeped by a third party, and information security cannot be guaranteed. Contents of the invention [0003] In view of the above problems, the present invention provides an information exchange method and system based on cloud services. [0004] The object of the present invention adopts following technical scheme to realize: [0005] The first aspect of the present invention provides a cloud service-based information exchange method, the method c...
