US 11,240,038 B2 · Ledger-based confidence model for content transfers across a communication network

Abstract

Embodiments of the disclosure provide a communication system and method to leverage distributed ledger technology as the basis upon which a trustless method can be deployed to validate file provenance and authenticity, while also supporting a strong form of non-repudiation. In one example, the method includes transferring electronic content from a sending communication device to the receiving communication device via Rich Communication Services. The method includes generating, at the sending communication device, file transfer parameters, identity signature and timestamp that are associated with the transfer of electronic content from the sending communication device. The method then includes causing the identity signature and timestamp to be written as part of a content transfer ledger. The method may also include securely providing the file transfer parameters associated with the transfer of electronic content from the sending device to one or more receiving communication devices as part of validating the electronic content.

Dependent claims

A communication system, comprising:

a communications interface;
a processor coupled to the communications interface;
and
a computer readable medium coupled with the processor, the computer readable medium comprising processor-executable instructions that include:
instructions that send electronic content via the communications interface to a receiving communication device;
instructions that generate a timestamp that is associated with the sending of the electronic content;
instructions that cause the timestamp to be written as an electronic record in a content transfer ledger;
instructions that provide file transfer parameters associated with the electronic content to the receiving communication device, wherein the file transfer parameters enable the receiving communication device to retrieve the timestamp from the content transfer ledger as part of validating the electronic content;
and
instructions that enable, after the electronic content is validated by the receiving communication device, a message digest to be accessed by a second communication device.

7 more elements

A method, comprising:

transferring electronic content from a sending communication device;
generating, at the sending communication device, a timestamp that is associated with the transfer of the electronic content from the sending communication device;
causing the timestamp to be written as an electronic record in computer memory as part of a content transfer ledger;
and
providing file transfer parameters associated with the transfer of the electronic content from the sending communication device to one or more receiving communication devices, wherein the file transfer parameters enable the one or more receiving communication devices to retrieve the timestamp from the content transfer ledger as part of validating the electronic content;
and
enabling, after the electronic content is validated by at least one communication device of the one or more receiving communication devices, a message digest to be accessed by a third communication device.
