Efficient Prevention of Credit Card Leakage from Enterprise Networks

Matthew Hall, Reinoud Koornstra and Miranda Mowbray, "Efficient Prevention of Credit Card Leakage from Enterprise Networks", in B. de Decker et al. (Eds.) CMS 2011, LNCS 7025, pp.238-240, 2011.

We have developed a new approach to the problem of preventing the leakage of credit card numbers in traffic on a large enterprise network. In contrast to a previously-used method, it has higher throughput, and it can be partly implemented in hardware without any additional libraries.
