Abstract: A method for communication between microservices, performed by a first host machine node, includes: obtaining a first microservice instance located on the first host machine node, determining a first microservice to which the first microservice instance belongs, and determining a list of triples corresponding to the first microservice according to the first microservice. The list of triples corresponding to the first microservice includes at least one triple, each triple of the at least one triple includes a visitor of the microservice, a visited party of the microservice, and an access port, and the visitor of the microservice of each triple included in the list of triples corresponding to the first microservice is the first microservice. The method also includes determining, by the first host machine node, an access policy of the first microservice instance according to the list of triples corresponding to the first microservice.

Abstract: A feature processing method and device for a motion trajectory, and a computer storage medium. The method may have a client device acquiring a motion trajectory generated by a user behavior to obtain an ordered point set, and each trajectory point in the ordered point set may have a position element and a time element. The method may further use information in the position element and the time element to convert the motion trajectory into an image. Furthermore, by performing image processing on the image, the method may obtain one or more feature vectors in the motion trajectory.

Abstract: The invention provides a compliance detecting method of payment applications in a virtualized environment, and pertains to the field of security technology of payment applications. The detecting method is used for compliance detection for PCI DSS isolation demands. The detecting method can determine whether it is a compliance state by analyzing the current virtual machine domain and its connection from data stream, and can also determine whether it is a compliance state by analyzing the purity of network flow of virtual machines. The detecting method is suitable for a virtualized environment and makes the detection of compliance accurate in the virtualized environment, thus being advantageous for guaranteeing the security of payment applications.
