Smart Identity Card

Artiest conception of the actual prototype (the real card has the chip on the back)

European countries establish eID systems, while often debating the privacy benefits anonymous credential systems provide. Are these advanced systems feasible and efficient enough on a standard eID card?

Anonymous credential systems are a powerful primitive to establish privacy for the users as well as security guarantees for issuers and service providers. At IBM Research, we established the first anonymous credential system on a standard Java Card. The credential system was autonomous, that is, did not rely on help from the terminal, used strong key-sizes and was quite fast.

In fact, we realized the credential system on an eID specimen with some years old off-the-shelf hardware underneath.
