Abstract: Systems and techniques for authentication of impaired voices are described herein. A voice profile may be generated for a user. An audio stream may be received including an authentication voice of the user. It may be determined that the authentication voice does not match a first set of authentication criteria. The audio stream may be compared to a second set of authentication criteria. The user may be authenticated based on the comparison.

Abstract: Systems, methods, and storage media for pre-approving onboarding to a payment platform, executing on a processing device are disclosed. Exemplary implementations may: access a node network; determine a first entity associated with a first node of the plurality of nodes is not a member of a payment platform; determine a total strength of connections of the first node to one or more nodes of the plurality of nodes exceeds a predetermined threshold value; and flag the first node of the plurality of nodes for an offer of onboarding to the payment platform consequent to determining the total strength of connections of the first node to the one or more nodes of the plurality of nodes exceeds the predetermined threshold value.

Abstract: A multi-port network communication device includes a plurality of ports for the reception and transmission of addressed data packets which include media access control address data, a forwarding mechanism for directing packets received at any of said plurality of ports to at least one of the plurality of ports, a memory for the selectively controllable storage of permitted media access control addresses, and means for restricting forwarding of packets from the device in response to an examination of media access control data in said packets and said permitted media access control addresses. The forwarding of a unicast packet having a source address and a destination address is prevented when neither of those addresses in the unicast packet corresponds to a permitted media access control address. The forwarding mechanism prevents the forwarding of multicast or broadcast packets to ports which are not connected to devices having permitted media access control addresses.
