Abstract: Third parties are prevented from obtaining proprietary information that a content provider might not want to expose. Targeting data used to enable a selection service to select targeted or supplemental content can be passed as an anchor in a uniform resource locator or stored in a parent file for a page. A second file can reside in an inline frame (iFrame) on the page that is able to pull the targeting data from the parent page, if in the same domain, or parse the parameters from the data in the anchor. The targeting data can be submitted to a selection service, which can return parameters specifying content or a type of supplemental content to be displayed. The request submitted to a supplemental content provider can come from a nested iFrame in a separate domain, such that the targeting data or source of the parent file cannot be obtained through the nested iFrame.

Abstract: Distributed compression of a data file can comprise a master server module for breaking the data file into data blocks and for transmitting the data blocks to worker server modules. A first worker server module can compress a first data block using a first compression algorithm, resulting in a first compressed data block. A second worker server module can compress the second data block using a second compression algorithm, resulting in a second compressed data block. The first and second compression algorithms can comprise the same algorithm or different algorithms. An archive module can save the first and second compressed data blocks in an archive file for storage or for transmission over a communication network. The worker server modules also can compress the respective data blocks using multiple compression algorithms and can choose the highest compressed result.

Abstract: Protecting a host network from a flood-type denial of service attack by performing statistical analysis of data packets in the network. The statistical analysis comprises comparing evaluated items in the data packets to threshold values and detecting the attack when the statistical items exceed the threshold value. A countermeasure can be initiated to protect the host network from the attack.
