Visa’s Rolls Out New Blockchain LucidiTEE – Tackles Concerns related to misuse of sensitive user data, when shared with third-parties.

Visa’s LucidiTEE claims to be the primary system to allow a number of events to collectively compute on large-scale personal knowledge whereas guaranteeing policy-compliance even when the enter suppliers are offline and permits equity to all output recipients. The venture, from the analysis arm of Visa –  goals to tackle rising issues related to misuse of sensitive user knowledge when shared with third-parties. 

It’s a system they declare supplies transparency and management to customers by: 

  1. Implementing agreed-upon insurance policies on what capabilities may be evaluated over personal knowledge (even when the customers are offline).
  2. Implementing the set of events with whom the outcomes are shared. For this stage of management, the system should guarantee coverage compliance, and so they exhibit, utilizing fashionable functions, the necessity for history-based insurance policies, the place any determination to compute on customers’ knowledge is dependent upon prior use of that knowledge. Furthermore, the system should algorithmically guarantee equity: if any social gathering will get the output, then so do all sincere events. It’s an open analysis problem to assemble a system that ensures these properties in a malicious setting.

From the dense, prolonged paper referred to as  LucidiTEE: Coverage-based Honest Computing at Scale: 

“In mild of the widespread misuse of private knowledge, we allow customers to management the sharing and use of their knowledge, even when offline, by binding that knowledge to insurance policies. A coverage specifies the allowed operate, circumstances guarding the execution (based mostly on the historical past of all prior computations on that knowledge), and identities of the enter suppliers and output recipients. For this stage of management, we intention for a pc system that ensures coverage compliance to the enter suppliers, and equity (i.e., both all or no social gathering will get the output) to the output recipients, with out requiring these events to belief one another or the compute host. Lately, trusted execution environments (TEEs), reminiscent of Intel SGX and Sanctum enclaves, are discovering functions in outsourced computing on sensitive knowledge. Nevertheless, since TEEs are on the mercy of an untrusted host for storage and community communication, they’re incapable of implementing history-dependent insurance policies or equity.”

“As an example, towards a user’s want that solely an mixture operate over her complete knowledge is revealed, an adversarial host can repeatedly consider that mixture operate on completely different subsets of her dataset, and study the person information. The adversary may additionally collude and ship the output solely to a subset of the output recipients, thus violating equity. This paper presents LucidiTEE, the primary system to allow a number of events to collectively compute on large-scale personal knowledge whereas guaranteeing that the aforementioned insurance policies are enforced even when the enter suppliers are offline and guaranteeing equity to all output recipients. To that finish, LucidiTEE develops a set of novel protocols between a community of TEEs and a shared, append-only ledger. LucidiTEE makes use of the ledger solely to implement insurance policies; it doesn’t retailer inputs, outputs, or state on the ledger, nor does it duplicate execution amongst the individuals, which permits it to scale to giant knowledge and a big quantity of events. We exhibit a number of policy-based functions together with private finance, federated machine studying, truthful n-party data trade, and personal set intersection for medical information.”

In accordance to the paper, LucidiTEE was trialled on Hyperledger Cloth and Tendermint –  however it seems it may also be used on forkless public blockchains that use a proof-of-stake consensus system. 

The paper concludes that LucidiTEE allows events to collectively compute on personal knowledge, utilizing protocols (between TEEs and a shared ledger) to be sure that all computations present equity and comply with history-based insurance policies, even when any subset of events act maliciously. The ledger is just used to implement insurance policies (i.e., it doesn’t retailer inputs, outputs, or state), letting them scale to a big quantity of events and huge knowledge.
