Service privacy disclosure detection method based on association graph and Internet of Things service platform

Abstract

The invention belongs to the technical field of privacy information protection of service sharing in an Internet of Things environment, and discloses a service privacy disclosure detection method based on an association graph and an Internet of Things service platform, which formulate a unified security policy protocol based on a use purpose for privacy information at two aspects of confidentiality and integrity. The method comprises the steps of according to the privacy information used in the service business execution process, constructing a dependency graph of the service and the privacy information; constructing a dependency relationship graph between the services according to the calling relationship between the services; constructing a cross-service service and privacy information two-dimensional matrix by using the service and privacy information dependency graph and the dependency graph between the services; and dynamically detecting whether privacy information is leaked in aservice calling process through a breadth-first traversal algorithm. The method can well adapt to the service cross-domain sharing and collaborative development in the Internet of Things environment,and provides the basic technical support for the privacy information protection during the service sharing process.

Description

technical field [0001] The invention belongs to the technical field of privacy information protection for service sharing under the Internet of Things environment, and in particular relates to a service privacy leakage detection method based on an association graph and an Internet of Things service platform. Background technique [0002] With the entry of major Internet giants into the Internet of Things, the competition in the Internet of Things industry has intensified, and a new model of building an Internet of Things service industry ecology around "platformization" has initially formed. IoT service developers can realize service reuse, integration and sharing on the platform, and develop new IoT services. Users need to provide some necessary personal privacy data when using IoT services. During the service combination process, service providers need to expose some personal privacy data to third parties. When personal privacy data is released, users cannot access the exp...
