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

Embodiment Construction

[0050] The technical solutions of the embodiments of the present invention are applied to an application scenario of controlling data circulation between cloud services with conflicting interests in cloud composite services. By adopting the technical scheme of the embodiment of the present invention, it is possible to avoid the circulation of sensitive data between cloud services with conflicting interests in cloud composite services.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The present invention proposes an information flow control method, including: acquiring data input into cloud services; judging whether the data is sensitive data; if the data is sensitive data, judging whether the data is sensitive according to the security label of the data Data conforming to preset sensitive data input rules; if the data is not data conforming to preset sensitive data input rules, prohibiting the data from being input into the cloud service. The above processing process realizes the identification of sensitive data that may bring conflicts of interest to cloud services, and effectively intercepts it, which can solve the problem of data conflicts in cloud composite services and avoid conflicts of interest in cloud services in cloud composite services.

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...
