Abstract: A computer-implemented method for protecting user identity within online content providing environments uses a security content management system (CMS) including at least one processor and a memory. The method includes identifying a request for an online content item associated with an online device. The online device is associated with actual device data. The method also includes determining a first characteristic value associated with the actual device data of the online device. The method further includes generating, by the processor, substitute device data. The substitute device data represents at least the first characteristic value. The method also includes providing the substitute device data to an online content provider.

Abstract: Systems, methods, and computer program products involve identifying a first IP block having a first set of IP addresses and a second IP block having a second set of IP addresses, the first set of IP addresses different from the second set of IP addresses. A first expected number of IP reassignments for the first IP block can be determined. A first number of IP reassignments between the first IP block and the second IP block can be identified. The first number of IP reassignments can be compared against the first expected number of IP reassignments. The first IP block and the second IP block can be merged into an IP allocation pool based, at least in part, on the comparison.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for improving geographic targeting of digital content. In some implementations, a targeting request that identifies a target geographic region is received. Groups of geographic regions that each include the target geographic region and at least another geographic region are identified. Combined targeting accuracies are computed for the groups of geographic regions. One or more of the groups of geographic regions are selected based on their combined targeting accuracies being higher than a targeting accuracy for the target geographic region. Data describing the selected one or more groups of geographic regions is provided for output in response to the targeting request.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for improving geographic targeting of digital content. One of the methods includes receiving a targeting request that identifies a target geographic region; identifying one or more groups of geographic regions that each include at least two geographic regions, including the target geographic region, wherein the one or more groups of geographic regions are identified based on respective combined targeting accuracies, the respective combined targeting accuracy of each of the one or more groups being higher than a targeting accuracy for the target geographic region; and providing data describing the identified one or more groups of geographic regions in response to the targeting request.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for analyzing queries. One of the methods includes obtaining a plurality of queries submitted from a plurality of different client devices; determining a source geographic location for each of the plurality of queries based on information associated with a client device from which the query was submitted; determining a destination geographic location for each of the plurality of queries based on the respective first text portion of the query; determining a vertical market category for each of the plurality of queries; receiving a request to analyze queries according to a first vertical market category and at least one of a source geographic location or a destination geographic location; using one or more indexes to identify queries responsive to the request; and presenting data describing the queries responsive to the request.

Abstract: Systems, computer-implemented methods, and computer-readable media are provided to target internet-based services on a geographic location relating to a plurality of candidate geographic locations. A targeted geographic location may be provided based on usefulness, to a user probabilistically located among the plurality of candidates, of internet-based services being targeted thereon. From a first server, a plurality of candidate geographic locations may be obtained, each of which may be associated with a client IP address and a plurality of candidate confidence levels. A plurality of route-utility factors for each respective candidate geographic location, a plurality of probabilistic utility scores for each respective candidate geographic location, and an aggregate probabilistic utility score may be determined for each candidate geographic location.
