Method and system for securing data from an external network to a non point of sale device
First Claim
1. A method, performed by a data control system, for securing data on a local area network in communication with an external network, the 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 the external network;
(b) determining whether the data received from the external network is destined for a non-point of sale device; and
(c) allowing the data to be sent if it is destined for a non-point of sale device.

Abstract
A data control system allows non-point of sale devices (135, 155) on the LAN to receive data from an external network (160) when established conditions are met. The data control system may allow the data to be sent to a non-point of sale device (135, 155) only if the data has not been received via a secure connection reserved for point of sale devices (125, 145). The secure connection is, for example, a virtual private network connection. The data control system may also allow the data to be sent to a non-point of sale device (135, 155) only if the data is associated with a communication session initiated by the non-point of sale device (135, 155). The data control system may also allow the data to be sent to the non-point of sale device (135, 155) only if it is not received from a restricted source. The restricted source may be, for example, a payment host (170), a secure host (180) or any unidentified source.
