Digital Identity Management
Blockchain-based digital identity management lets a person control their verifiable credentials and choose which data to share, without a central registry. It relies on decentralized identifiers (DID) and fits the European eIDAS 2 framework and its digital identity wallet. Unknown Gravity deploys these systems.
Digital identity management is one of the key pillars of the digital age. With the increase in cyber threats and the need to ensure privacy, the use of blockchain technology in identity management adds decentralization, traceability and access control. Learn how our platform takes advantage of blockchain technology to give you more control over what data you share and with whom.
01 / Increased security with blockchain
The use of blockchain in digital identity management ensures that every transaction and data associated with the identity is backed by state-of-the-art cryptography. With the security of a decentralized network, the risk of fraud or identity theft is minimized.
02 / Facilitating interoperability between systems
Blockchain-based solutions allow multiple platforms to be integrated without compromising security or privacy. Digital identities managed on blockchain can be easily validated and verified, improving the operational efficiency of companies and users.
03 / GDPR compliance: whose responsibility it is
GDPR compliance is the responsibility of the controller (Art. 24 of Regulation (EU) 2016/679), not of the technology. We design the architecture to make it easier, with data minimization, information kept off-chain and only hashes on-chain, precisely because immutability makes the rights to rectification and erasure harder (Arts. 16 and 17). We apply data protection by design (Art. 25). In the EU, digital identity is also governed by Regulation (EU) 2024/1183, which creates the European Digital Identity Wallet.
04 / Reducing Administrative Costs and Complexity
With blockchain, organizations eliminate middlemen, reducing operating costs. In addition, the automation of processes using smart contracts allows for a more efficient management of digital identities.
05 / Scalability and the future of digital identities
The architecture is sized for a growing number of users, with the choice of network and data model adjusted to each case. As digitization advances, blockchain-based digital identities gain weight as a verification layer, within the framework set by Regulation (EU) 2024/1183.
FAQ
Frequently asked questions
What is a digital identity in blockchain?
A blockchain digital identity is a representation of an individual's personal or professional data, registered and managed through a blockchain network. This identity is secure, transparent and controlled by the user himself.
How does blockchain guarantee the privacy of my digital identity?
Blockchain adds privacy by storing data in a decentralized and encrypted way. You decide what data you share and with whom, and the recorded hash is immutable, which makes any alteration detectable. Personal data stays off-chain, because immutability makes rectification and erasure harder (Arts. 16 and 17 GDPR).
Is it safe to use blockchain for digital identity management?
Yes, blockchain is highly secure due to its decentralized nature and the use of advanced cryptography. There is no single point of failure, making it more resistant to cyberattacks compared to traditional systems.
