  • Methods, systems, and apparatus for fragmented file sharing
    Patent number: 10423764
    Abstract: Systems, methods, software, and apparatus are described for facilitating the distribution and management of fragmented content. In one embodiment, a packager packages content into fragments and generates a manifest including policies and metadata associated with the content. A downloader obtains the manifest, and uses it to obtain the content from one or more uploaders. For example, a downloader might forward a search request to one or more trackers, which, in turn, are operable to locate one or more uploaders that can meet the request, subject to any relevant policy limitations. The uploaders forward fragments to the downloader, subject to any relevant policy. The downloader assembles the content from the fragments. The operations and interactions of the entities can be subject to policy limitations associated with the fragments, the content as a whole, or the like.

  • Secure transaction systems and methods
    Patent number: 10412071
    Abstract: Systems and methods are described that use tag authentication and presence verification techniques in connection with a variety of transactions. In certain embodiments, an authentication device may verify the authenticity of a secure tag by determining whether the secure tag stores secret information provisioned by a trusted authority. In some embodiments, such an authentication process may be performed without exposing the secret information to the authentication device, thereby maintaining integrity of the secure tag. In other embodiments, insecure tags and/or tags that do not include secret information are used.
