The invention relates to the technical field of Internet application, in particular to a transport-layer-characteristic-based traffic classification method for the Internet application. The method comprises the following steps of: acquiring a data packet which serves as training data, and constructing a classifier by utilizing transport layer characteristics of a data stream extracted from the data packet; and classifying the data stream extracted from a subsequently acquired data packet by utilizing the constructed classifier. The application type of the stream can be identified only by extracting the transport layer characteristics of the stream without knowing load contents such as a port number, a characteristic field and the like of the data packet. The privacy of a user is uninvolved, and a dynamic-port-number-based or encrypted stream can be identified by the technology. Moreover, the method is highly accurate and integral, novel application can be identified and the user can be prompted to check suspected virus attack streams.

The invention relates to a mobile malicious user identification method and system based on a communication behavior rule, and the method comprises the steps: collecting data in desensitized mobile communication flow data based on a non-uniform sampling method, and carrying out preprocessing; analyzing and extracting call behavior characteristics, short message behavior characteristics and time distribution characteristics of the user by utilizing a behavior mode in a mobile communication behavior analysis model based on the preprocessed mobile communication sampling data; based on the preprocessed mobile communication sampling data, analyzing and extracting social attribute characteristics of the user by utilizing a communication network in a mobile communication behavior analysis model; and constructing a mobile malicious user identification model based on the extracted user behavior mode characteristics and the extracted user social attribute characteristics. The behavior rule of theuser can be analyzed based on the desensitization data, whether the user is a mobile malicious user or not is recognized, timeliness is achieved, and the mobile malicious user can be recognized withhigh accuracy under the condition that personal privacy of the user is not involved.

The invention relates to a time, geographic location, and network-based social networking system and method, thereby realizing functions of vehicle location, social activity organization, advertisement publishing, news information releasing, offline and online transaction services and information inquiring reservation. Especially, the system includes a novel mobile IC card reader and a method.

Therefore, information transmitting becomes efficient; the traffic situation is improved; the positive social contact orientation is guided; the transaction becomes simple, convenient and rapid; and the life style of the human being is improved. And thus the great social benefits are generated.

The invention discloses an intelligent payment method based on different merchants. The method comprises the steps of (1) orderly inputting brand types of cards held by a user into a mobile terminal and carrying out locking, (2) activating the mobile terminal after receiving a payment request, (3) locking a merchant and downloading real-time discount information of the merchant, (4) matching the discount information and information of the cards held by the user and giving a payment scheme, and (5) storing payment information and locking the mobile terminal. According to different merchants, combined with the cards held by the user, the optimal payment is carried out, thus the user can enjoy a most preferential consumption mode, the management and monitoring of the cards held by the user are facilitated, and the convenience of user consumption is greatly improved.

The invention discloses a network asset information obtaining method and device and a readable storage medium. The method comprises: obtaining at least one to-be-processed network flow log from a network flow auditing device of a target network; analyzing the to-be-processed network flow log to obtain network asset positioning data; and obtaining corresponding network asset information based on the network asset positioning data. According to the invention, the detection range of network asset detection is expanded, and the information security of network asset detection is improved.

The invention provides a vehicle-mounted terminal convergence media delivery method and a vehicle-mounted convergence media interaction terminal, and belongs to the technical field of convergence media delivery. According to the method, fusion media delivery is triggered through user operation, after a user selects an address, the remaining browsing duration is estimated, and the remaining browsing duration, the selected address and vehicle-mounted terminal information are sent to a server in a sound code mode; a server searches for matched offline and online convergence media, screens out convergence media delivery content, segments the convergence media delivery content, converts the convergence media delivery content into acoustic code strings, and sends the acoustic code strings to the vehicle-mounted terminal; and the vehicle-mounted terminal analyzes the converged media delivery content and delivers the converged media delivery content in sequence. And the server performs convergence media content adjustment according to the frequency of the commodity types clicked by the user, and performs arrival reminding according to the address selected by the user. The converged media delivery is triggered by the user, accurate delivery of online shopping groups and old people is realized, and excessive user privacy is not involved.

The invention provides a target audience interest analysis method and device, equipment and a storage medium, and relates to the technical field of data analysis. The method comprises the steps of obtaining a target sample set; calculating the proportion of the target sample set in each interest label according to the matching amount of the target sample set and a preset sample set; wherein the preset sample set comprises multiple groups of sample data and at least one interest label; and determining a target interest label from at least one interest label according to the proportion of the target sample set in each interest label. Compared with the prior art, the problem that cost is high due to the fact that interest of sample data is analyzed through a large amount of investigated individual-level data is avoided.

The invention relates to an industrial wireless network coexistence management method, in particular to an industrial wireless network non-centralized coexistence management method based on information coordination. Aiming at the coexistence problem caused by mutual interference of a plurality of industrial wireless networks, the invention provides the non-centralized coexistence management method applied to industrial wireless networks for the first time, and the non-centralized coexistence management method specifically comprises two parts of incomplete information interaction and non-centralized resource coordination. For the incomplete information used for coordination, on the premise of considering privacy protection, the content of the incomplete information is definitely defined, and guidance is provided for non-centralized resource coordination; and aiming at the aspect of non-centralized resource coordination, the requirement of network transmission data packet deadline is considered, a network utility function is designed, based on coordinated incomplete information, the network utility function is designed, and a network occupied resource strategy is independently adjusted. The network gain is maximized, the time required for convergence of the algorithm is reduced, and the interference between coexisting networks is minimized.
