Determining point of interaction device security properties and ensuring secure transactions in an open networking environment

Abstract

The present invention provides for determining point of interaction device security properties for secure transmission of a transaction between a plurality of electronic devices, such as point of interaction (POI) devices or computer systems (or both), over a public communication system, such as the Internet. In one embodiment, a communication is established between a first electronic device and a second electronic device using a public network. Digital certificates are then exchanged to validate the parties and to provide a secure channel for transmission of data. Device security properties of the first electronic device are determined based on information transmitted by the first electronic device to the second electronic device thereby allowing the second electronic device to accept or reject a transaction request from the first electronic device based (in part) on the device security properties of the first electronic device.
