When a mobile device such as a smart phone comes within range of a location device, the mobile device inputs a location token from the location device and a travel token is created from a mobile device token and the location token. The mobile and location tokens may include data elements indicating not only identity, but also such other characteristics as an authorization or infection risk level. Tokens may be digitally signed, preferably with an independently verifiable signature that also encodes time. Mobile and location devices may be created and issued by a tracking service provider, which may also store tokens, analyze travel tokens with respect to a location's risk level, and update mobile device and location tokens to change a status of the mobile or location device.

System and method for verifiably proving proximity

A method and system for displaying an advertisement at a user device comprising receiving a content stream at the user device comprising an advertisement queuing point, monitoring the content stream for the advertisement queuing point at a client stream assembler module of the user device, communicating an advertisement query signal comprising client metadata from the client stream assembler module to a decision proxy, receiving an advertisement decision signal comprising an advertisement location identifier at the client stream assembler module, requesting an advertisement based on the advertisement location identifier and receiving and displaying the advertisement corresponding to the advertisement location identifier on a display associated with the user device.

Method and system for assembling content streams with advertisements from multiple advertisement vendors

A content delivery network and method for operating the same includes a content delivery network (CDN) origin server and a content delivery network edge server receiving a request for a first content from a first client device and communicating the request for the first content to the content delivery network origin server. The CDN origin server communicates a pull signal to a publisher origin server when the request for the first content is a first request, receives the first content from the publisher origin server and stores the first content. The CDN origin server communicates the first content to the first client through the CDN edge server.

Method and system for communicating content to a client device by pulling content from a publisher from a content delivery network when first requested by the client device

A system, apparatus, and method provide messaging, between a headend system and a set top box. A distributor determines and provides an assigned communication identifier and an assigned server host address, that correspond to one of one or more first servers, to each of one or more set top box clients. The first servers maintain a persistent connection with the set top box clients and provide messaging, presence, and routing features via the persistent connection. A gateway service provides a gateway for one or more headend servers to communicate with the set top box clients through the first servers. A server controller provides administrative graphical user interfaces for operators to monitor and control health checks, configuration changes, and collect statistics for the distributor, first servers, and the gateway service.
