Handshake

Track your proximity to COVID-19

Create your location's anonymous id:

Type a unique phrase that no-one else would choose

Please make sure it is something no-one else would choose

Such as a few random words that you can remember

This ensures that your location doesn't end up with the same anonymous ID as somewhere else

For example: "fierce tree folks butter" (it doesn't have to include your place name)

Tip: use the idea described at https://preshing.com/20110811/xkcd-password-generator/.
Unique Phrase:



How this works:

Your phrase is 'hashed' to form a unique id.

This is done in your browser, your phrase in plain text never leaves your phone or computer.

Assuming you used a phrase which included what would be a strong unique password, it is virtually impossible to go from the hash alone back to your phrase.

However, people still may be able to reidentify your location, especially those who know handshake with your location.

This is Open Source and so you can check the source code or "View Source" in your browser as it is only HTML and Javascript.

No guarantee of privacy, accuracy of information or any guarantee whatsoever is provided.
