The invention discloses a method and device for recognizing a social-media account. The method for recognizing the social-media account comprises the steps of receiving an identify label of the social-media account to be recognized; inquiring the confidence level of the social-media account to be recognized according to the identify label, wherein the confidence level is a numerical value obtained by pre-calculation and used for reflecting the authenticity of the social-media account to be recognized; if the confidence level of the social-media account to be recognized is inquired, judging whether the confidence level exceeds a confidence threshold value or not; if it is judged that the confidence level exceeds the confidence threshold value, determining that the social-media account to be recognized is a first account, wherein the first account is the account used by a real user; if it is judged that the confidence level does not exceed the confidence threshold value, determining the social-media account to be recognized as a second account, wherein the second account is an account operated by a computer. According to the method and device, the effect of improving the accuracy of recognizing the authenticity of the social-media account is achieved.

The invention provides a microblog zombie user detection method based on a relational graph. A data collection module and a relational graph analyzing module are used in the method. The data collection module is used for collecting data of a known zombie user and selecting a sample user from the data. The relational graph analyzing module is used for judging whether the sample user is the zombie user or not. The detection method includes the first step of building the relational graph between the known zombie user and the sample user, the second step of initializing malicious scores of the users, the third step of calculating relevance numerical values of the users, calculating and updating the malicious scores of the users according to the relational graph and a propagation rule, the fourth step of judging whether the malicious scores of the sample user are spread and restrained or not, and the fifth step of judging if the spread and restrained malicious scores of the sample user are larger than a threshold value, if yes, the sample user is the zombie user. Through the utilization of the social relation and semantic relation of the zombie user to find and recognize other zombie users, the judging efficiency of the zombie users is improved. The microblog zombie user detection method is applied to social networks, provides safer and effective detection services for the social networks, and improves safety of the social networks.

The invention discloses a detecting method for zombie users of social networks, comprising the following steps of: extracting items and information distributed by detected users in a predetermined time period; analyzing the items and the information according to behavior properties and characteristics of the zombie users, and classifying the users according with the behavior properties and the characteristics of the zombie users as suspected zombie users; and performing the semantic analysis for the suspected zombie users according to the items and the information, and classifying the users according with the semantic features of the zombie users as the zombie users. The effectively automatic detecting method for the zombie users of the social networks provided by the invention can conveniently and accurately detect the zombie users in the social networks to guarantee the original service intention of the social networks, so that network communities and information distribution communication platforms capable of reflecting collective intelligence and group hotspots are built.

The invention discloses a method of registration service and a network ethnic group central control node and a system, and belongs to the technical field of communications. The method includes that the network ethnic group central control node receives change information which is sent by a router after storage service in router self buffer memory is changed, a login request is generated according to service binding information in a service information list, and according to a service identifier, service behavior describing information and an identification of the network ethnic group central control node, the service identifier and the service behavior describing information correspond to the service binding information, the service binding information which is stored by the change information self is updated by the change information, and the login request is sent to a service analysis server to conduct login. The method enables the network ethnic group central control node to be used as a service providing main body to provide service for a user terminal, therefore, a user has more selections to obtain service which is needed by the user terminal, main body obtaining service is provided by service with a non-busy link or a relatively-near distance link, and efficiency of the terminal obtaining service is improved.
