Conference: Digital identity and distributed systems

Blockchain technologies are flexible concerning the identity of the participants. Some of them are structurally public and open to access: Bitcoin, for instance, has a lack of trust policy; anyone can read and write on the ledger, creating anonymous identities at will. Other kinds of blockchains require access permissions: Hyperledger Fabric, for instance, provides a based Certification Authority structure to participate in the network.

Distributed protocol development handles identity management by pursuing the guideline of permissioned DLTs. Once an external identity (through Bank authentication systems according to the EBA RTS regulation on Strong Authentication, Identity Provider, SPID, …) is associated with the one inside the system, the identity management takes form by defining related permissions. For instance, how to distinguish who has permission to read the ledger, arrange transaction orders, write changes to the ledger, and other possible operations. When the definition of permissions takes place, an access policy is then declared, in other words, a series of rules which are consulted by a central entity at each request for access to a resource.

The challenge is to integrate the identities provided by external entities with the internal network protocol, define the access policies related to such identities, and include security mechanisms to ensure that the policies are respected.

In this conference, we will take stock of the Italian and European initiatives on the subject of the integration of public and private digital identity systems in DLT and blockchain systems.


The conference aims to highlight studies, evidence, and guidelines on how public systems of digital identity (such as SPID, CIE, CNS) or private (such as banking SCA, digital signatures, Certification Authority services) and distributed systems (such as DLT, Blockchain) can collaborate to strengthen identification, authorization and recognition mechanisms in digital processes.
