Data Privacy Day: IBM launches Identity Mixer, an anonymous credential system
In an email, IBM Research Zurich snagged my attention by saying
Identity Mixer uses a “cryptographic code acts as an agent knowing all
of your secrets, while revealing as little as possible. If you need to
prove that you are from a country to e-vote instead of typing in your
address it will simply respond with ‘yes’ or ‘no’. If you need to prove
that you are at least 21 to rent a car, it will say that you are between
25-100 years old. The technology also works similarly for credit card
transactions. The result, you prove who you are without revealing
anything that can be stolen.”Identity Mixer could be used for
online services, web-based subscriptions, e-commerce, health care
provider portals, voting, car-to-car communications, public transport
ticketing systems and more. It solves the Catch-22 paradox of proving
who you are, without providing other sensitive personal information.
Instead of transmitting a user’s credentials, Identity Mixer can be used
to convince a verifier that your attributes satisfy specific properties
without leaking other unnecessary personal information. In other words,
it allows the user to reveal only selected pieces of personal
information to third parties.A privately listed video explains
that after you’ve revealed your identity by signing up on a site, the
anonymity technology Identity Mixer can be used to allow the user to
later access that service in private. Researching diseases via a health
care portal was given in one example. Identity Mixer could be used in
several scenarios such as polling and web-based subscriptions, e-commerce,
or even used in a digital wallet that contains credentials certified by
a trusted third party. IBM said it’s important to note that “the issuer
of the credentials has no knowledge of how and when they are being
used.”
