From the UK Mail:
Cyber-security company High-Tech Bridge set out to test the confidentiality of 50 of the biggest internet companies by using their systems to send a unique web address in private messages…
During the ten-day operation, six of the 50 companies tested were found to have opened the link.
Among the six were Facebook, Twitter, Google and discussion forum Formspring.
Hmmm. Reading the article I am not sure if I should be concerned, outraged or skeptical. I do not know if the test as it is described proves that Facebook is reading my e-mails…but it might. On the one hand it seems to be another breech in our privacy that online companies continue to pursue in order to sell us more stuff. I find that a bit creepy. However personally I am less concerned with Google knowing stuff about me that I am with the IRS.
For dentists I believe it does underscore the fact that free mail accounts like g-mail and Hotmail should not be considered secure and should never be used to send private health information to another dentist.
