US Patent 10506104 Identity verification using blockchain technology

Systems and methods for using blockchain technology for the purpose of securely identifying parties to a communication. The method may comprise receiving a request to establish a communications connection between a first entity and a second entity in a telephony environment and writing a first digital identity associated with the first entity to a first data block in an immutable chain of blocks, in response to determining that the first entity is recognizable as a trusted entity. The blocks may be associated according to a defined cryptographic relationship. A second digital identity associated with the second entity may be written to a second data block in the immutable chain of blocks, in response to determining that the second entity is unrecognizable as a trusted entity.
