Aletheia for Python

PyPi Thanks! License Documentation

A Python 3 implementation of Aletheia.

This is how we get from

I read it on the Internet, so it must be true.

to

Yesterday, the Guardian had a story about a prominent politician doing something they weren't supposed to be doing. The video footage was certified authentic, and the author of the article stands by her work.

Aletheia is a little program you run to attach your name -- and reputation -- to the files you create: audio, video, and documentation, all of it can carry authorship, guaranteed to be tamper proof.

Once you use Aletheia to sign your files, you can share them all over the web, and all someone has to do to verify the file's author is run Aletheia against the file they just received. The complication of fetching public keys and verifying signatures is all done for you.

If this sounds interesting to you, have a look at the documentation or even install it and try it out yourself.

The Goal

I want to live in a world where journalism means something again. Where "some guy on the internet" making unsubstantiated claims can be fact-checked by organisations who have a reputation for doing the work of accurate reporting. More importantly though, I think we need a way to be able to trust what we see again.

New technologies are evolving every day that allow better and better fakes to be created. Now more than ever we need a way to figure out whether we trust the source of something we're seeing. This is an attempt to do that.

How to Use it

The process is pretty straight forward. Install the system dependencies as described in the setup documentation and then:

$ pip install aletheia

Once it's installed, you can verify a file to try it out. Use this one as a starting example.

Command Line API

$ aletheia verify path/to/test.jpg

Python API

from aletheia.utils import verify

verify("path/to/test.jpg")

More details can be found in the command line API and Python API documentation.

Colophon & Disambiguation

This project is named for the Greek goddess of truth & verity -- a reasonable name for a project that's trying to restore truth and verified origins to the web. It also doesn't hurt that the lead developer's wife is Greek ;-)

It's been noted that there's another project out there with the same name. The two projects are totally unrelated, despite the identical name and the fact that both lead developers are named "Daniel".
