Themer by MyColorScreen Acxiom, the Quiet Giant of Consumer Database Marketing It peers deeper into American life than the F.B.I. or the I.R.S., or those prying digital eyes at Facebook and Google. If you are an American adult, the odds are that it knows things like your age, race, sex, weight, height, marital status, education level, politics, buying habits, household health worries, vacation dreams — and on and on. Right now in Conway, Ark., north of Little Rock, more than 23,000 computer servers are collecting, collating and analyzing consumer data for a company that, unlike Silicon Valley’s marquee names, rarely makes headlines. It’s called the Acxiom Corporation, and it’s the quiet giant of a multibillion-dollar industry known as database marketing. Few consumers have ever heard of Acxiom. Such large-scale data mining and analytics — based on information available in public records, consumer surveys and the like — are perfectly legal. For Acxiom, based in Little Rock, the setup is lucrative. But such profits carry a cost for consumers. In March, however, Ms.

Chip and PIN security busted High performance access to file storage Security researchers have demonstrated a gaping security hole in Chip and PIN credit card authorisations which undermines trust in the technology as a means to verify retail purchases. Cambridge University security researchers have demonstrated how it might be possible to trick the card into thinking it’s doing a chip-and-signature transaction while the terminal thinks it’s authorised by chip-and-PIN. The flaw creates a means to make transactions that are "Verified by PIN" using a stolen (uncancelled) card without knowing the PIN number. Fraudsters would insert a "wedge" between the stolen card and terminal, tricking the terminal into believing that the PIN was correctly verified. It's not surprising that the attack works when a terminal is offline but it works when the terminal is connected too. The man-in-middle attack outlined by the Cambridge researchers doesn’t work at ATMs but it can work regardless of the amount spent in retail transactions.
