Does anyone know of a service (ideally docker image - probably with app) that can be used to securely share family pictures?
The idea is, that some relatives don’t respect wishes of not posting to social media and to prevent this we want to securely share images they can look at but not do anything else with.
Even if I send an image to my mom and she knows not to post anywhere, maybe my aunt wants to see that picture, asks my mom to send it to her and then she posts it, without us knowing.
Probably only works with an app because a browser can’t block screenshots.
Is there anything like this out there? Doesn’t have to by anything special. Just a web backend for us to upload pictures and a client (probably through a URL) that can then browse them without allowing for screenshots, sharing, downloading, etc
The family member problem may be solved by either talking to your mom or not sending any pictures anymore after she shared them with your aunt. You can’t fix social issues through technology.
Browsers contain DRM for services like Netflix that will block most attempts at screenshots, though the lower versions of DRM (often used for low res video) may allow screenshots and recordings. In theory something using Fairplay or the highest level of WideVine can be cracked to get the full digital copy out, but that’s done by dedicated pirate groups using software or equipment your aunt won’t have.
As others said, there’s still the analog hole, you can’t prevent someone from photographing another’s screen.
A DRM image service would probably work for artists and photographers with cheap, incompetent customers who wouldn’t be able to figure out why they can’t take screenshots, but I think your aunt will just use her camera to take a picture of your mom’s screen.
Yes, i am aware that taking pictures of the screen is always possible. I was looking for a best effort solution, because blocking screenshots and sharing would definitely do most of the work. I don’t know why people immediately jump to DRM. It’s just an image viewing app that I’m looking for.
The social issue is, that my SIL already asked that none of her kids be posted to social media, but my BIL ignored that.
But since there doesn’t seem to be anything like that, I guess I’ll have to tell them that if they ignore it, they’re will be no more pictures
