A method for securely rendering digital documents, comprising: retrieving, by a document platform, a digital document and at least one usage right associated with the digital document from a document repository, the at least one usage right specifying a manner of use indicating the manner in which the digital document can be rendered; storing the digital document and the at least one usage right in separate files in the document platform; determining, by the document platform, whether the digital document may be rendered based on the at least one usage right; and if the at least one usage right allows the digital document to be rendered on the document platform, rendering the digital document by the document platform. view more

A rendering system adapted for use in a distributed system for managing use of content, said rendering system being operative to rendering content in accordance with usage rights associated with the content, said rendering system comprising: a rendering device configured to render the content; and a distributed repository coupled to said rendering device and including a requester mode of operation and server mode of operation, wherein the server mode of operation is operative to enforce usage rights associated with the content and permit the rendering device to render the content in accordance with a manner of use specified by the usage rights, the requester mode of operation is operative to request access to content from another distributed repository, and said distributed repository is operative to receive a request to render the content and permit the content to be rendered only if a manner of use specified in the request corresponds to a manner of use specified in the usage rights. view more

A computer-implemented method of rendering digital content by at least one recipient computing device in accordance with usage rights information, the method comprising: receiving the digital content by the at least one recipient computing device from at least one sending computing device only if the at least one recipient computing device has been determined to be trusted to receive the digital content from the at least one sending computing device; receiving, by the at least one recipient computing device, a request to render the digital content; determining, based on the usage rights information, whether the digital content may be rendered by the at least one recipient computing device; and rendering the digital content, by the at least one recipient computing device, only if it is determined that the content may be rendered by the at least one recipient computing device. view more

A recipient apparatus for rendering digital content in accordance with usage rights information, the recipient apparatus comprising: one or more processors; and one or more memories operatively coupled to at least one of the one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause at least one of the one or more processors to: enable the receipt of the digital content by the recipient apparatus from at least one sending computing device only if the recipient apparatus has been determined to be trusted to receive the digital content from the at least one sending computing device; receive a request to render the digital content; determine, based on the usage rights information, whether the digital content may be rendered by the recipient apparatus; and render the digital content only if it is determined that the content may be rendered by the recipient apparatus. view more

A computer-implemented method of distributing digital content to at least one recipient computing device to be rendered by the at least one recipient computing device in accordance with usage rights information, the method comprising: determining, by at least one sending computing device, if the at least one recipient computing device is trusted to receive the digital content from the at least one sending computing device; sending the digital content, by the at least one sending computing device, to the at least one recipient computing device only if the at least one recipient computing device has been determined to be trusted to receive the digital content from the at least one sending computing device; and sending usage rights information indicating how the digital content may be rendered by the at least one recipient computing device, the usage rights information being enforceable by the at least on recipient computing device. view more

A sending apparatus for distributing digital content to at least one recipient computing device to be rendered by the at least one recipient computing device in accordance with usage rights information, the sending apparatus comprising: one or more processors; and one or more memories operatively coupled to at least one of the one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause at least one of the one or more processors to: determine if the at least one recipient computing device is trusted to receive the digital content from the sending apparatus; send the digital content, by the sending apparatus, to the at least one recipient computing device only if the at least one recipient computing device has been determined to be trusted to receive the digital content from the sending apparatus; and send usage rights information indicating how the digital content may be rendered by the at least one recipient computing device, the usage rights information being enforceable by the at least on recipient computing device. view more
