As we are concerned about privacy, I am curious just to understand if lemmy can be at some point exploited by someone to profile its users.

What if database entries are encrypted, so that a person cannot match email and username with the requests in the urls?

Users' client create encryption key on client side. Would it make sense?

This all happens before the database even gets asked for information. The web server will make a log of the requests as they come in before responding.

At minimum the web server needs to know where to send the data back to.

Thanks, makes sense

If you consider the server to be malicious, why would you trust any claim that the data is encrypted?

[–] [email protected] 1 points 1 year ago

I am thinking more of a Meta "threads" -like situation. Not necessarily malicious, just a different privacy expectations between user and provider

It's still a fingerprint, the most vague information correlated with other data points can make a useful fingerprint. This is how a lot of the companies can track you even if you aren't logged in, you using any service creates a pattern that with enough aggregate data can be used to approximate who you are.

Thanks, it looks like privacy on internet is really a mirage

Somehow the server has to be able to look up the user's subscriptions so it knows what posts to show them.

I am mainly thinking about matching navigation history with identifiable information... You are right, It's a tricky thing...

I also wonder, if lemmy becomes a thing, with numbers in the same order of magnitude of reddit, if and how gdpr will affect server admins... Having a privacy anonymization tool built in by design might avoid headaches on the long term
