Abstract: System and methods for selecting and serving a targeted digital advertisement to a user are provided. In one implementation, an advertisement platform server receives an ad transaction pixel from a user device. Based on the ad transaction pixel, the server initiates a discovery process in order to discover the identity of the user device. The server then receives a device targeted ad request from the user device, and sends a device targeted ad response to the user device based on results from the discovery process.

Abstract: Systems, methods and computer program products for measuring conversion in online digital advertising solve different technical challenges in measuring digital advertising conversion across browsers, applications, domains and devices without deploying cookies.

Abstract: System and methods for determining a relationship between an application-level identifier and a network-level identifier are provided. In one implementation, a discovery server receives a data request that includes an application-level identifier and a transitory network-level identifier. Based on the transitory network-level identifier, the discovery server determines a stable network-level identifier, and further maps the application-level identifier to the stable network-level identifier.

Abstract: A method and apparatus provides protection for network infrastructure discriminating between trusted and non-trusted sources. According to at least one embodiment, packets containing information for the control plane are marked at Layer-2. According to at least one embodiment, interface groups are applied, whereby a router can determine whether a packet should be marked or not. According to at least one embodiment, the marking of control packets is done by encapsulating the packets at Layer-2 in a way that uniquely identifies the Layer-2 frames as carrying trusted control information, which is referred to as control encapsulation. Routers exchange control packets (such as routing protocol or signaling protocol packets) using the control encapsulation. Rate-limited queuing the unmarked control packets has the benefit of supporting routers without the control encapsulation functionality while eliminating the susceptibility of the router to flood-type DoS attacks on its control plane.
