Digital Identity and Decentralised Identifiers: The New Infrastructure of Trust

Digital transformation has exposed an uncomfortable truth: our personal data is too often controlled by third parties who determine how it is stored, accessed and monetised. For businesses and institutions, this dependence on centralised architectures translates into rising risks: privacy breaches, compliance exposure, and the erosion of stakeholder trust. The emerging answer at both European and global level is Self-Sovereign Identity (SSI), powered by Decentralised Identifiers (DIDs). This paradigm shifts control back to individuals, enabling them to manage and share their digital identity selectively, securely and verifiably, while meeting the demands of regulation and social expectations for transparency.

The emerging answer at both European and global level is Self-Sovereign Identity (SSI), powered by Decentralised Identifiers (DIDs). This paradigm shifts control back to individuals, enabling them to manage and share their digital identity selectively, securely and verifiably, while meeting the demands of regulation and social expectations for transparency.

From centralised digital identity to self-sovereignty

Traditionally, digital identity has been managed by central authorities: governments, financial institutions, large technology platforms. While effective in the short term, such systems have proven fragile, siloed and vulnerable.

Self-Sovereign Identity changes the equation. Personal attributes — such as residency, academic qualifications or professional licences — are stored directly in a user-controlled wallet, cryptographically verifiable through blockchain. Instead of depending on centralised databases, individuals own and manage their identity, while trusted issuers validate credentials that can be shared on demand.

Real-world applications

Healthcare: secure and shareable medical records

A patient can keep their medical history, prescriptions and test results in a digital identity wallet. When moving between hospitals or consulting specialists, they share only the data required for that specific interaction. Authenticity is confirmed through DIDs, ensuring data integrity and avoiding duplication or fraud.

Education: verifiable diplomas and certificates

Universities can issue blockchain-verified diplomas and certifications. Students hold them in their wallet and present them to employers, who verify authenticity instantly without contacting the issuing institution. This reduces administrative delays, costs and the risk of falsification.

Employment and HR: faster, safer onboarding

HR departments can, with a candidate’s consent, access verified credentials such as identity, qualifications and references in seconds. This accelerates onboarding while maintaining compliance with privacy regulations.

Mobility and travel: digital passports and driving licences

European pilot projects are already testing self-sovereign digital passports and driving licences. Travellers disclose only necessary attributes (e.g. “over 18” or “EU citizen”), without revealing extraneous personal details.

Public services: transparency and efficiency

Citizens accessing government services — from school enrolments to tax benefits — can share only the data strictly required. This streamlines administrative checks, strengthens security and reduces exposure of sensitive information.

Regulation as a catalyst

The European Digital Identity Framework and eIDAS 2.0 regulation are accelerating the deployment of SSI across the EU. The vision is a single, secure, interoperable identity solution recognised across Member States.

This is more than a technical evolution. It represents a cultural and societal shift, positioning digital identity as a source of competitive advantage. For enterprises, it signals a chance to stand out as trusted custodians of customer data. For governments, it enables transparency, inclusion and digital sovereignty.

Why this matters for business leaders

For C-level executives, investing in decentralised digital identity solutions addresses three strategic imperatives:

1. Regulatory readiness – preparing for evolving European and global standards on data privacy and interoperability.

2. Reputation and trust – demonstrating a proactive commitment to protecting stakeholders’ data.

3. Process innovation – unlocking new business models and services enabled by verifiable, portable and interoperable digital identities.

Beyond technology: towards a trusted digital society

The challenge goes beyond building wallets or blockchains. It is about creating a pan-European trust infrastructure where businesses, institutions and individuals operate with common standards and shared incentives.

Self-Sovereign Identity and Decentralised Identifiers are set to become the foundation of the next generation of digital services. Not an optional add-on, but a strategic necessity for a future where innovation, privacy and trust must advance together.
