    CPC classification number: H04L9/3247

    Abstract: A first request for content from a client device is received. The first request includes a resource locator provided by an authorizing data service to authorize the client device to obtain the requested content. The resource locator includes a first digital signature associated with authorization of the client device to access the requested content, and a second digital signature associated with authorization of delivery of the requested content for access by the client device. An occurrence of an event is identified that indicates a change in the delivery of the requested content to the client device. A third digital signature associated with a changed delivery of the requested content is generated. A new resource locator is provided to the client device that includes the first digital signature and the third digital signature.

    Abstract: A method includes receiving, by a processing device of a content sharing platform, a request for desired content from a client device, the content being stored in a content delivery network (CDN). The method further includes generating, based on data available to the content sharing platform, a partial trust metric associated with the client device, wherein the partial trust metric is to be used by a CDN server to make a decision regarding access to the desired content by the client device. The method further includes generating a response to the content request, wherein the response comprises one or more resource locators for accessing the desired content in the CDN, and the partial trust metric. The method further includes sending the response to the client device to enable the client device to request the desired content from the CDN server using the resource locator(s) and the partial trust metric.
