METHOD AND SYSTEM FOR SECURING DATA FROM A POINT OF SALE DEVICE OVER A LAN
First Claim
1. A method, performed by a data control system, for securing data on a local area network having one or more point of sale devices and one or more non-point of sale devices, the method comprising the steps of:
- (a) determining the data is from a first point of sale device on the local area network;
(b) preventing the data from the first point of sale device from being sent to a non-point of sale device; and
(c) allowing the data from the first point of sale device to be sent to a second point of sale device on the local area network.

Abstract
A data control system for a local area network (100) prevents point of sale devices (125,145) from sending data to non-point of sale devices (135,155) but allows point of sale devices (125,145) to send data to other point of sale devices (125,145) on the local area network (100). The data control system may, define a point of sale network within the local area network. The data control system may define a point of sale network (120,140) within the local area network (100) and determine the data is from the point of sale network (120,140) if the data is associated with a service set identifier corresponding to a wireless point of sale network (120) or a port corresponding to a wired point of sale network (140). The data control system may also allow data to be sent to a point of sale device (125,145) only if it is represented on a white list of approved point of sale devices (125,145). The data control system may also prevent wireless point of sale devices (125) from sending data to wired point of sale devices (145) and prevent wired point of sale devices (145) from sending data to wireless point of sale devices (125).
