Abstract: Methods and systems are described for distributing and receiving fax transmissions via a data connection that is owned by a service provider. In one embodiment, a fax server receives a signaling protocol invite from a telephone service provider in response to the telephone service provider receiving, over a circuit switched network and from a source device, an incoming call signal to a fax telephone number of the service provider. The server responds to the invite by establishing a data connection based on the signaling protocol with the telephone service provider, where the data connection is owned by the service provider. The server receives an incoming fax message that is in a fax format and is routed by the telephone service provider as the source device transmits the incoming fax message. The server transmits the fax message to a destination address.
Abstract: In one aspect, the present disclosure provides a system and method for distributed data storage and delivery using blockchain. For example, a file can be received from a participant and split into constituent files. A hash value for the received file and each of the constituent files can be generated, and the constituent files can be encrypted using one or more predetermined or user selected encryption keys. The encrypted files can be stored in at least one storage location. Upon receiving a file retrieval request, each file of the plurality of encrypted files can be retrieved and decrypted using the one or more predetermined or user selected encryption keys. A hash value for each decrypted file can be generated and compared to hash values for the corresponding files of the plurality of constituent files, or a hash value for the recombined constituent files can be generated and compared to the hash value for the original file. Other aspects also are described.
