A user portrait construction method and device

Abstract

The embodiment of the invention provides a method and a device for constructing a user portrait. The method comprises the following steps: acquiring a device log corresponding to a user to be analyzedfrom a device log generated by each network access device, and expanding the information of the device log corresponding to the user to be analyzed to obtain a historical access log of the user to beanalyzed; According to the history access log, counting a plurality of history access behaviors of a user to be analyzed, and determining an access behavior attribute tag of the user to be analyzed according to the plurality of history access behaviors; By using the preset situation awareness analysis strategy, analyzing the historical access log, and obtaining the threat level attribute label, which is used to characterize the security threat level of the user to the network. According to the access behavior attribute label and the threat degree attribute label, the user portrait of the userto be analyzed is constructed. Through the scheme, the user portrait can not only show the user's access behavior, but also show the threat degree of the user to the visited network.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for constructing a user portrait. Background technique [0002] User portrait is the labeling of user behavior attributes. The existing Internet user portrait construction method is to first obtain the historical online behavior logs of Internet users, and then analyze the obtained historical online behavior logs of Internet users to establish an Internet user profile. The user's access behavior attribute label to build a user portrait. [0003] As mentioned above, the current user profile construction method mainly analyzes the acquired historical online behavior logs of users accessing the network, analyzes the attribute labels of the user's network access behaviors, and constructs user profiles based on these attribute labels. However, the user portraits constructed according to the above methods are mainly focused on Internet access, and t...

Problems solved by technology

However, the user portraits constructed according to the above methods are mainly focused on Internet access, and the constructed user portraits are mainly used to provide personalized and accurate recommendations for users. Roughly shows the user's access behavior, and the user portrait constructed by the above user portrait construction method cannot show the threat level of the user to the accessed network
