QR Code Security – Are we ready to discuss the risks?

The Quick Response codes we see on everything from movie posters to business cards are becoming the ubiquitous contact links of an entire new generation of mobile devices and the people who use them. Originally invented in Asia at the end of the last millennium (circa 1994 Japan, actually), these matrix or 2D (two-dimensional) barcodes

Of Secrets and Bleeding Hearts: How Far Have We Really Come?

In the early 1920s, the Enigma machine was a portable encryption machine with rotor scramblers used for encoding and decoding confidential messages.

Ever wonder what the use of stealing millions of email addresses is? All those often downplayed, ‘low sensitivity’ data breaches have massive potential to create enough uncertainty for people to eventually call a 1-800 number, even it it means speaking to a passive-aggressive tech support professional.

People often confuse information protection with IT security. One of the reasons I resist the compartmentalization of my craft as an automated, software driven process is that as important as it is, IT security not only reduces the scope of my work by at least two-thirds, but it misses the point of what it means

Should You Feel Bad About Blocking Online Ads?

I’m not a fan of banner ads, browser pop-ups nor of what’s come to be called behavioural advertising. I find that such promotion largely falls into two categories. The kind that has nothing to do with what I’m interested in, and the kind that is surprisingly well targeted to my personal interests. Since the former

‘Tis the Season for Telephone Scams

If you haven’t already received a call from a ‘Microsoft Windows Center’ insisting on helping you get rid of ‘lots of hacking file in your computer’, chances are that you will, and soon. This unfolds according to a pattern that has been in use for the past few years and begins with a long distance
