Tiny Privacy Tip 🔒✨:

This might sound trivial but
when you are posting a photo online, always be mindful of any visible reflective surfaces before posting it.

Make sure nothing
unintended can be seen in:

👉 Mirrors  ​

👉 Glasses  ​

👉 Sunglasses  ​

👉 Glossy frames 🖼️​

👉 Laptop displays 💻​

👉 Glossy monitors 🖥️​

👉 #DEFCON badges  ​​

👉 ETC  ​

In general, it’s always good to take a few seconds to zoom in and have a quick look at what *else* can be seen before posting 👀

Remember, once the data is out it is very hard to remove it.

Better be careful than sorry!

@Em0nM4stodon Thank you! And is it too much if I suggest to also remove the photo metadata, so that you don’t implicitly share the picture location, date, time, …?

@gaufff @Em0nM4stodon If you share on #discord, the metadata will be autostripped (to save space on their servers I assume)!

@astroorbis @Em0nM4stodon Waw! And I must admit I have always considered discord as a bit « evil », that is definitely an upside 😅

Thank you!

@gaufff @Em0nM4stodon Discord stores a lot, but that doesn't mean they're all that bad :3

IRC is amazing though honestly, I've been hosting a server for a while and use it when I'm on a shitty connection and Discord won't load

@gaufff I think Masto already does that.

@Em0nM4stodon Here's me wishing we could have a polarized lens filter we could attach to our phones. That'd get rid of all reflections instantly.

Like other comments already figured out, take into account the #metadata of your pictures.
I use #ScrambledExif from #F-Droid on #android to share grafical content.
You simply share to the app icon and than directly to the app where you want to public.
It's simple, easy and fast.
Get used to it.

In a similar vein, make sure that things like your fingerprints aren't easily shown in any photos you share online. Take this almost hilarious example from a couple years ago as to why you should be careful about including your fingerprints in photos you upload.

A drug dealer was identified because of a picture of a block of cheese he posted online, and was subsequently arrested. In the photo, it clearly showed his fingerprints thanks to modern camera technology allowing for higher image resolutions.

If law enforcement is able to capture a person's fingerprint reliably through a photo, then so can anyone else. With enough time and skill, a bad actor use it for nefarious purposes and potentially even unlock your phone with a rubber mold.

Remember, you can always change a password, but you can't change your fingerprint.

A photo of cheese just got a UK drug dealer sentenced to 13 years in prison

The UK’s Merseyside Police identified a drug dealer and convicted him of conspiracy to supply cocaine, heroin, MDMA, and ketamine with the help of a photo of a wedge of stilton.
