Abstract: Embodiments of the present invention provide a system for secure verification of identity data. A request for verification of a customer for a client's product or service is received, the request including a baseline set of customer information. This received baseline set of customer information is compared to customer information stored on a private block chain network to determine whether the received baseline set of customer information matches the stored information for the same customer. If there is a match, a virtual customer key is generated or copied from the private block chain network and transmitted to a client system. The client system can then provide subsequent requests for customer identity verification or additional information about that customer by presenting the virtual key.

Abstract: A method for capping a stem web including passing the stem web through a first nip against a first heated nip roll so as to partially cap the stems; cooling the web; and passing the stem web through a second nip against a second heated nip roll to completely cap the stems to a diameter “D”. In preferred embodiments the two nips are on opposite sides of a larger central cooled roll positioned between the heated rolls. Preferably, the reaction forces between the rolls are measured and controlled at each end of each other heated rolls. The invention is particularly adapted to making abrasive particles that are attached to a driving mechanism via headed stem fasteners formed by the method.
