Reusable Identity: The Future of Modern Digital Society


Reusable Identity

Reusable Identity

In the digital era we live in, identity management plays a crucial role in our daily lives. The increase in online services and digital transactions has made it essential to develop secure, reliable, and reusable identities. In this article, we will delve deeply into the concept of reusable identity, focusing on the fundamental role of:

  • Identity proofing
  • Innovation in biometric recognition
  • Integration of blockchain in ensuring the security of digital identities


Reusable Identity

With Reusable Identity refers to the ability to utilize a single digital identity to access various online services without the need to create new accounts or repeatedly provide personal information. This approach aims to simplify the authentication process, simultaneously enhancing user security and privacy.

Identity Proofing

Identity proofing constitutes the crucial process through which the legitimacy of an individual requesting access to a system or online service is confirmed. This phase is essential to ensure that the provided identity is authentic and indeed belongs to the person making the request. Identity proofing further strengthens reusable identities, ensuring that only legitimate users can benefit from them.

Biometric Recognition

Biometric recognition represents a milestone in digital security. This technology leverages an individual’s unique and measurable characteristics, such as fingerprints, facial recognition, and iris scanning, to conduct secure and efficient identity verification. The utilization of these individual-specific elements ensures both security and non-replicability.


Blockchain, a distributed and immutable technology, is revolutionizing how we manage digital identities. Through the use of decentralized ledgers, particularly with Soulbound Tokens, blockchain provides a secure and transparent solution for storing, validating, and decentralizing identities, thereby reducing the risk of fraud and unauthorized access.

Synergistic Integration

Now that we’ve understood what these aspects entail, we can further our argument by relating the concepts. Combining reusable identities, identity verification, biometric recognition, and blockchain is feasible but requires collaboration among various service providers and technology developers. To ensure its effectiveness, it’s important to have stringent security standards and protocols. Despite facing challenges, the advancement of these technologies promises a safer future for digital identities.

Several benefits can arise from this development:

  • High Security: integrating biometric recognition with identity verification ensures a high level of security, as it requires the identification of unique physical characteristics of the user.
  • Simple Authentication: biometric recognition simplifies authentication by eliminating the need to remember complex passwords and offering a more intuitive user experience.
  • Fraud Prevention: using biometrics for identity verification significantly reduces online fraud, as it is difficult to replicate or forge biometric characteristics.
  • Enhanced User Experience: employing biometrics for identity verification provides users with a more convenient and seamless experience, reducing complexities during authentication.
  • Multilayered Security: integrating blockchain adds a layer of security, ensuring that information is immutable and distributed across a decentralized network.
  • Privacy Protection: the decentralized nature of blockchain guarantees greater privacy protection, allowing users to maintain control over their personal information.
  • Transparency and Immutability: blockchain transparently and immutably records every identity-related transaction, providing a secure and traceable record of online activities.

Once again, while there are challenges, the combined progress of these technologies offers a safer future for digital identities. We need to focus on privacy management, standardization, and user education to maximize the benefits of this evolution.


The synergistic integration of identity proofing, biometric recognition, and blockchain represents a significant step forward in digital security, paving the way for the adoption of reusable and secure identities, immune to the risk of identity theft. This convergence not only simplifies access to online services but also enhances security levels, anticipating a future where digital transactions and online interactions occur in a safer, more efficient, and transparent manner, while also providing advanced protection against identity theft.

A concrete example of how this integration can offer a significant advantage in the use of reusable identities is represented by Cyberneid’s products:

  • Identikyc enables companies to verify individuals’ identities with certainty, safety, and privacy, using an electronic identity document such as an ID card or passport.
  • eidWallet is an EUDI wallet that decentralizes the electronic identity on the blockchain by using Soulbound Tokens, eliminating the need for any centralized, controlled, or trusted authority.
  • Instasign allows users to sign documents with just a few clicks, anywhere, protecting their identity from identity theft. This provides total control over their signatures and security.
  • Wink&Pay is an innovative payment solution that utilizes biometric technology to authorize transactions easily, securely, and quickly.
  • Wink&Go is a revolutionary access solution that uses biometric recognition technology for secure and immediate access to work or public transportation.
