Nonetheless, currently deployed SSI managers lack data resilience. Consequently, one's identity is lost if the device holding it becomes inaccessible. We achieve data resilience through identity backups. Unfortunately, there is no research on the matter. Thus, we discover that traditional backup systems need eight additional requirements to become suitable for identity backups. Then we describe two existing solutions and introduce a novel one designed by us. A comparison between them follows, from which we conclude that our novel solution satisfies the most requirements. We then extend an existing SSI manager with a proof-of-concept implementation of our solution. Our implementation consists of three main components. The first one takes care of identity recovery. The second one allows verifiers to check whether identities and their backups are consistent before verifying their attested claims. And the last mechanism takes care of access revocation.
