Abstract: Storing and accessing information in a distributed data storage system includes: using erasure code, encoding a data block of the information to generate an encoded data block comprising both parity data and the data block, wherein by using the erasure code the data block may be reconstituted from a subset of the encoded data block, the subset comprising less than all of the data block; distributing, for storage, portions of the subset across a plurality of network storage locations such that the subset is not stored in its entirety at any one of the plurality of network storage locations; retrieving the distributed portions from the plurality of network storage locations; reconstituting the subset from the distributed portions that are retrieved; and using the erasure code, reconstituting the data block from the reconstituted subset of the encoded data block.

Abstract: A method of transmitting a covert message over a network from an origin device to a destination device includes using selection a plurality of network paths, network channels, and network tunnels to signal to the destination device symbols. Sequences of the symbols are interpreted by the destination device as values in an n-base number system. The values are decoded by the destination device to obtain the covert message. Some preferred implementations use a binary number system and some use a hexadecimal number system. Some utilize network path selection and incorporate network watermarks, by which the network path that was selected for each received packet is determined. Network paths preferably are differentiated from one another by redirects that are storage servers in an overlay network. Network communications can be opened between the origin device and destination device for continuously communicating packets without signaling symbols when no covert message is being transmitted.

Abstract: A network communications method utilizing a network watermark for providing security in the communications includes creating a verifiable network communications path of nodes through a network for the transfer of information from a first end node to a second end node; verifying the network communications path of nodes, by the first end node, before communicating by the first end node information intended for receipt by the second end node; and once the network communications path of nodes is verified by the first end node, communicating by the first end node, via the verified communications path of nodes, the information intended for receipt by the second end node; wherein the network watermark represents the verifiable network communications path of nodes.
