PlainContext sharing photos via social media
for example, lets imagine what one could figure out from some photos with your friends:
- your look and identity
- their look and identity
- your connections, if you’re posting some people’s photo more frequently, it could mean more close connections with them (close friends, family)
- some clues about your and their social status, hobby, political and religious views and other data (via presence of specific clothes, accessories, cars etc.)
- time and location of photo (even with disabled/stripped geolocation tags, just by surroundings)
- thus some clues about your real location and schedule (place where you work/study, live, travel or just often visit etc)
regarding storing photos in some cloud, not publicly sharing them in social media, it limits access to:
- you
- people you’re sharing these photos with
- company who owns the cloud (or social media)
- government/law enforcement who could force the company to give them access to your data
- some potential attackers who could get access to your cloud by hacking, social engineering etc.
with basically the same possible consequences, except the fact that there are usually stored originals, with better quality and some metadata that is usually getting stripped on sharing (creation timestamp, location tags etc.)
it’s up to you to decide how critical is it.
