Abstract: Systems, computer programs and methods are provided to protect consumer credit card data and/or other private information by tying such information to a particular hardware identification number, such as without limitation an individual Media Access Control (MAC) Address of a user's computer and/or mobile device. Credit card or other data is registered and associated with a hardware identification number for computer(s) or mobile device(s) of the registrant. Then, when a transaction involving the credit card occurs, the hardware identification number for the device initiating the transaction is compared with the registered hardware identification number for the credit card. If the numbers do not match, the transaction is not allowed to complete, preventing those without the hardware identification from using the registered credit card, debit card, or other registered item.

Abstract: A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.
