Abstract:
A sender uses a double-write protocol to pass data to a recipient using a dead drop network architecture. The sender sends, to a dead drop domain, a data payload to store at the dead drop domain, and receives payload access information corresponding to a payload dead drop where the payload data is stored. The sender sends, to the dead drop domain, one or more instances of metadata including the payload access information to store at the dead drop domain, and receives metadata access information corresponding to one or more metadata dead drops where the metadata is stored. The sender provides the metadata access information to one or more recipients. A recipient uses the metadata access information to read the corresponding metadata dead drop. The recipient then uses the payload access information from the metadata to read the payload dead drop and receive the payload data.

Claim (Index 8):
A system for controlling access to a data payload in a dead drop domain comprising a plurality of storage nodes connected by communication links, the system comprising:\n a processor for executing computer program instructions; and a non-transitory computer-readable storage medium storing computer program instructions executable by the processor to perform steps comprising:\n receiving, from a sender and by the dead drop domain comprising the plurality of storage nodes connected by communication links, a payload write request requesting to write a data payload to the dead drop domain; \n writing the data payload to a payload dead drop on a storage node in the dead drop domain responsive to the payload write request; \n sending payload access information corresponding to the payload dead drop to the sender; \n receiving a metadata write request requesting to write metadata to the dead drop domain from the sender, the metadata comprising the payload access information and having associated time-to-live (TTL) information specifying a duration for the metadata to persist in the dead drop domain; \n writing the metadata to a metadata dead drop on a storage node in the dead drop domain, the metadata persisting at the metadata dead drop for the specified duration; and \n sending metadata access information corresponding to the metadata dead drop to the sender.
