Vision
▪ FOR WHOM? DataVaults will enable a new mode of collaboration/business relationship between individuals and
organizations that would like to manage/process the personal data of individuals
▪ WHY? Turn the personal data value chain into a multi-sided and multi-tier ecosystem governed by smart
contracts to safeguard data ownership, privacy and usage and attribute value to all entities that generate value
within this chain and especially data owners.
DataVaults aims to deliver a framework and a platform that has personal data,
coming from diverse sources in its centre and that defines secure, trusted and
privacy preserving mechanisms allowing individuals to take ownership and control
of their data and share them at will, through flexible data sharing and fair
compensation schemes with other entities
Target Users: Individuals – Data Providers – Data Seekers & Data Analysts 2

Road Ahead for Blockchain-based Trust Anchors
▪ Classification in five main elements
▪ Governance
✓ Policies around identity and access management, on-boarding new members, secure key
management, data management policies and more
✓ Security Policy Enforcement
▪ Application
✓ Smart contracts reflecting the secure and privacy-preserving data exchange and sharing, with
third-party stakeholders, enable the business logic in the ecosystem
▪ Data
✓ Confidentiality and Data Protection
✓ On- and Off-Chain data maintenance with high levels of confidentiality
✓ Crypto primitives to be used – span from straightforward (i.e., encryption, signatures, HMACs,
etc.) to more advanced like DAA, Digital Twins, ABE, etc.
▪ Transactions
✓ How consensus of transactions is reached? Shared ledger updates
▪ Endpoint Vulnerabilities
✓ Trusted Platform Module (TPM) to run in the host user devices and the backend

Safeguarding for the Future
▪ Blockchain Ecosystem Rules and Permissions manage
onboarding of participants into the network and the roles within
the network
▪ Smart Contracts are self-executing, logical workflow agreements
to manage the access and use of value and data, third-party
applications will also be integrated
▪ On-chain Data Encryption where each data item can be
encrypted individually or collectively
▪ Blockchain consensus and rules for participants to agree on rules
for committing transactions and updating the shared ledger
▪ Blockchain Network & Systems for participant nodes stand in
their infrastructure and network, communicating through public
or private connections
5
▪ Identity and Access Management, Key Management via TPMs
▪ Information Security Guidelines & Policies, Security Training
▪ Application Security, Secure code development & guidelines
▪ Vulnerability and Risk Assessment
▪ Encryption and Key Management, Privacy Policies and Controls
▪ Industry specific standards and regulation
▪ Off-chain Data Security
▪ Secure and sustainable choice of consensus
▪ Fork management and maintenance
▪ Periodical Vulnerability Assessment & Risk Management
▪ Logging and Monitoring
▪ Endpoint Security and Patch Management
▪ BLOCKCHAIN ▪ Security & Privacy
