A new, free Google Chrome browser extension called Streak lets email senders using Google accounts see when recipients open email.
And, oh my, it also lets senders see who, exactly, opened the email, and where the recipient is located.
The bad news is that if you're thinking that you can just avoid installing Streak if you don't want marketers, creeps, phishers and spammers to see when and where you opened your email, so sorry to tell you, but that's just an irrational thought coming from la-la land.
Maybe I'm off track here (no pun intended), but it seems quite a bit of info is collected:
So, from one embedded image systems like Streak can determine:
Who opened their email
What time the email was opened
Where it was opened
What sort of device it was opened on
So even a newbie snooper could know where I am at the time.
Maybe could also extrapolate a lot more, e.g. two emails opened within minutes, one from an open wifi at a coffee shop and another 200 miles away from my cell phone.
OK, so who is that guy at the coffee shop reading my email?
Is that what you mean, Hazelnut? If so, I may try out for my junior cyberspy license.
