摘要： Location-based anomaly detection based on geotagged digital photographs. In some embodiments, a method may include identifying a completed transaction associated with a user. The method may also include determining a transaction geographic location associated with the completed transaction. The method may further include identifying a mobile device associated with the user. The method may also include identifying one or more geotagged digital photographs taken by the mobile device. The method may further include extracting one or more photograph geographic locations from the one or more geotagged digital photographs. The method may also include, in response to determining that the transaction geographic location is not within a threshold distance of any of the one or more photograph geographic locations, identifying the completed transaction as a suspicious transaction and performing a remedial action.

摘要： A method for optimizing network decision nodes is described. In one embodiment, the method includes generating an initial network of decision nodes constructed according to one or more rules, rearranging one or more decision nodes of the initial network based at least in part on a conversion of the one or more rules to a disjunctive normal form, analyzing the rearranged network of decision nodes in an upstream direction, and optimizing the rearranged network by merging two or more decision nodes of the rearranged network based at least in part on the analysis of the rearranged network. In some cases, the decision nodes include one or more levels of parent nodes and child nodes, each level of child nodes being connected to respective parent nodes. In some cases, the upstream direction is in a direction from the child nodes to the parent nodes.

摘要： A method for improving memory efficiency of production rule systems is described. In one embodiment, the method includes identifying a rule associated with production rule systems, constructing a production rule network based at least in part on the rule, identifying a positional constraint associated with the rule, and implementing an alpha memory gate in the production rule network based at least in part on the positional constraint. In some cases, the alpha memory gate is one of a plurality of nodes of the production rule network.

摘要： Systems and methods for identifying and removing a tracking capability from an external domain that performs a tracking activity on a host web page. Tracking capabilities of an external domain may be removed by altering web requests and/or responses to API calls. Once these tracking capabilities of the external domain have been removed, the altered web requests and/or altered responses to API calls may be transmitted to a web browser and/or entity making the API call thereby protecting user privacy while allowing the external domain to interact with the host web page.

摘要： Distinguishing between functional tracking domains and nonfunctional tracking domains on a host web page. In particular, a list of known tracking domains that load content into host web pages may be received. This list of tracking domains may include tracking domains that are functional and tracking domains that are nonfunctional. The tracking domains that are functional may be determined by evaluating various behaviors and characteristics of the tracking domains. Once functional tracking domains have been determined, these functional tracking domains may be allowed, and other tracking domains may be blocked from loading content onto host web pages thereby preserving the functionality of the web pages.
