At the moment, technology to reveal your pretty face all over again isn't exactly mature, but eliminating blur is an entire field of research.
If you're editing photos to hide your face after you take them, don't blur your face—block it out entirely.
It may be a less-ugly method—compared to, say, putting a giant black block over your head—but a blurry photo can be reverse-engineered.
This is most important when dealing with numbers and text (which is why you should never photograph your credit card, even if you blur the number).
The rule with sexting is that if you don't want everyone to see photos of you, don't send them to anyone.
This is good advice, but it's also an "abstinence only" approach.
If you decide to go through with it, there are ways to protect yourself.Before we say anything else on the subject: we don't generally recommend sending saucy pics over the internet.We've talked about this before, and our opinion hasn't changed.Just like sex in the real world, abstinence is the only thing that's 100% safe.However, we also know some of you are going to do it anyway—so again, just like sex in the real world, we think it's important to educate you on how to do it safely.This should go without saying, but if you want to remain anonymous in the event your photos end up in the wrong hands, be sure that no one can confirm it's you at a glance. Also be aware of any tattoos, birth marks, abnormalities, or unique features on your body that someone may recognize.
