Patent number: 10999063Abstract: A method of verifying a user transaction at a blockchain node is provided, the method including receiving at a communication device information provided by a user in a user transaction, generating a message in dependence on the received information and signing the generated message with a private key of a public-private key pair. The method including transmitting the signed message to a server, calling an execution function for executing code of the execution function, the execution function being for verifying that a public key of the public-private key pair matches the private key with which the message was signed, and passing the signed message to the execution function, executing the code to determine whether the signed message was signed with the private key matching the public key, and, based on the determination, verifying the user transaction so as to permit the user transaction to be recorded at a blockchain node.Type: GrantFiled: October 22, 2018Date of Patent: May 4, 2021Assignee: Cygnetise LimitedInventors: Shaun Keith Blake, Stephen John Pomfret

Patent number: 10367796Abstract: Roughly described, a method of recording a change of authorization state of one or more authorization agents, the method comprising: establishing a copy of a blockchain ledger at each of a plurality of blockchain nodes, wherein each of the blockchain nodes is associated with a different controlling entity; providing a public key/private key pair for a first of the blockchain nodes; receiving, from the communication device, a first message comprising: first data indicative of a change of authorization state of a first authorization agent associated with the first controlling entity, the first data being encrypted; and a digital signature based on the blockchain ledger and the private key; authenticating the message using the public key; adding a block to the blockchain ledger based on the first message, thereby to generate a new blockchain ledger that records the change of authorization state of the first authorization agent.Type: GrantFiled: January 5, 2017Date of Patent: July 30, 2019Assignee: Cygnetise LimitedInventors: Shaun Keith Blake, Stephen John Pomfret

Patent number: 9427973Abstract: A module for mounting and use in a postage meter for printing postage includes a housing and two ink cartridges for ink-jet printing, each of the cartridges having a flexible electrical circuit member operatively attached thereto, with one of the electrical circuits including a microprocessor. The housing consists of two lateral components, each containing one of the ink cartridges, a central panel component interposed between the lateral components, and elements for maintaining the components in assembly. The ink cartridges are placed into cavities formed by the lateral components, which are then assembled on opposite sides of the central component with the flexible circuit members suitably arranged, to produce the inking module. The central panel includes features for applying laterally outward biasing force upon the seated ink cartridges, and structure is provided on the module to facilitate mounting and retention in a postage printing machine.Type: GrantFiled: March 22, 2016Date of Patent: August 30, 2016Assignee: DATAPRINT TECHNOLOGY, INC.Inventor: John A Pomfret
