Problems solved by technology

However, there may be commercial competition among service providers, resulting in a conflict of interest (Conflict of Interest, COI) between cloud services
The existence of conflicts of interest between cloud services requires that cloud composite services must control the flow of information between cloud services to prevent sensitive data from flowing between cloud services with conflicts of interest along with message passing between cloud services, causing serious damage to relevant service providers. certain loss
[0003] The information flow control mechanism in the existing cloud composite services does not support the resolution of conflicts of interest, but only solves data confidentiality or integrity issues
The problem of conflict of interest not only involves the confidentiality and integrity of data, but also involves the problem of data conflict between cloud services with information flow, so the existing information flow control mechanism cannot solve the problem of conflict of interest in cloud composite services

Abstract

The invention provides an information flow control method. The method herein includes the following steps: acquiring the data that are input to cloud service; determining whether the data are sensitive data; if the data are sensitive data, based on the safety tag of the data, determining whether the data meet preset sensitive data input rules; and if the data do not meet preset sensitive data input rules, forbidding the inputting of the data to the cloud service. The aforementioned method can identify the sensitive data that may bring conflict of interest to the cloud service, blockages such sensitive data in an effective manner, can address data conflict in cloud composite service, and prevents the cloud service in the cloud composite service from having conflict of interest.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an information flow control method and device. Background technique [0002] Cloud combination service provides users with richer functions by organically combining multiple cloud services with different functions and from different service providers to form a new complex information system. During the working process of cloud composite services, information flows between various cloud services. However, there may be commercial competition among service providers, which leads to conflict of interests (Conflict of Interest, COI) among cloud services. The existence of conflicts of interest between cloud services requires that cloud composite services must control the flow of information between cloud services to prevent sensitive data from flowing between cloud services with conflicts of interest along with message passing between cloud services, causing serio...
