WISeKey International Holding Ltd (WISeKey), based in Geneva, Switzerland, announced on August 25, 2025, the convergence of WISeID, its people identity platform, and SEALCOIN, its object identity platform, into a unified decentralized identity framework intended for use within a decentralized internet environment. This next-generation WISeID builds upon WISeKey’s 25 years of experience in digital identity, creating a Self-Sovereign Identity (SSI) platform allowing individuals and connected devices to interact, transact, and authenticate securely with full autonomy.
WISeID was initially launched in 1999, alongside WISeKey’s Cryptographic Root of Trust, which is now embedded in over 7 billion devices, websites, and iOS systems globally. WISeKey states that this widespread deployment makes its infrastructure one of the most widely deployed identity platforms on the internet, with a mission to allow users to regain control of their digital identity.
The combined WISeID and SEALCOIN ecosystem leverages blockchain technologies and the Hedera Consensus Service (HCS) to issue and manage verifiable credentials for both people and devices. While trust anchors are recorded on an immutable ledger, all private user data remains off-chain, ensuring strong privacy protections, and certified identity verification methods, including physical, video, and AI-driven KYC, are seamlessly integrated. Users benefit from multi-factor authentication for secure access, an open-source framework ensuring interoperability without vendor lock-in, and Swiss-based data storage guaranteeing compliance with high privacy standards while maintaining user ownership of their data.
WISeKey has expanded WISeID’s capabilities with free identity validation via smartphone or computer camera, allowing users to confirm their identity by scanning an official ID and matching it with facial recognition. New digital certificates offer multiple levels of assurance, ranging from free email-only certificates to advanced and professional certificates incorporating verified personal or organizational details, and a new digital document signing solution enables users to sign PDFs directly from any device, with WISeID automatically generating secure single-use certificates for each signature. Enterprises can now also deploy WISeID corporate accounts, providing administrators with centralized control over employee and customer identities while streamlining the management of digital signatures.
Both WISeID and SEALCOIN now benefit from the rollout of the Quantum Root Key, a new Root of Trust developed by WISeKey using post-quantum cryptographic (PQC) algorithms to protect digital identities, communications, and systems against the disruptive power of quantum computing. The Quantum Root Key has already been created and will be made widely available once Microsoft and other operating systems and browsers adopt PQC roots, marking a critical advancement in securing global digital infrastructures for the quantum age. WISeKey notes that the rise of quantum computing, and algorithms like Shors algorithm, pose a fundamental threat to existing encryption schemes.

Quantum-Resistant Security Architecture
WISeID was among the first digital identity technologies on the Internet, launched in 1999 alongside WISeKey’s Cryptographic Root of Trust, which is now embedded in over 7 billion devices, websites, and iOS systems worldwide. This scale positions WISeKey’s infrastructure as one of the most widely deployed identity platforms on the Internet, created with the goal of enabling users to regain control of their digital identity.
Both WISeID and SEALCOIN now benefit from the rollout of the Quantum Root Key, a new Root of Trust developed by WISeKey that utilises post-quantum cryptographic (PQC) algorithms to protect digital identities, communications, and systems against the disruptive power of quantum computing. The Quantum Root Key has already been created and will be made widely available once Microsoft and other operating systems and browsers adopt PQC roots, marking a critical advancement in securing global digital infrastructures for the quantum age.
The latest enhancements to WISeID expand its capabilities with free identity validation via smartphone or computer camera, allowing users to confirm their identity by scanning an official ID and matching it with facial recognition. New digital certificates offer multiple levels of assurance, from free email-only certificates to advanced and professional certificates that incorporate verified personal or organizational details. A new digital document signing solution enables users to sign PDFs directly from any device, with WISeID automatically generating secure single-use certificates for each signature.
Features and Capabilities
Much of the world’s sensitive data currently relies on encryption to safeguard it from cybercriminals and unauthorized access. However, the rise of quantum computing, with its ability to execute complex mathematical operations such as factoring large prime numbers, poses a fundamental threat to existing encryption schemes. Algorithms once considered unbreakable will become obsolete in the face of quantum attacks, including those enabled by Shor’s algorithm. The solution is not simply extending key lengths but adopting an entirely new cryptographic paradigm, one that WISeKey is pioneering with its PQC-based Quantum Root Key, designed to secure digital assets in the post-quantum era.
The combined WISeID and SEALCOIN ecosystem leverages blockchain technologies and the Hedera Consensus Service (HCS) to issue and manage verifiable credentials for both people and devices. While trust anchors are recorded on the immutable ledger, all private user data remains off-chain, ensuring strong privacy protections. Certified identity verification methods, including physical, video, and AI-driven KYC, are seamlessly integrated. Users benefit from multi-factor authentication for secure access, an open-source framework that ensures interoperability without vendor lock-in, and Swiss-based data storage that guarantees compliance with the highest privacy standards while maintaining user ownership of their data.
In a digital landscape increasingly shaped by geopolitical tensions and the concentration of identity services within a few dominant platforms, WISeID provides a critical alternative. Unlike identity providers that exploit user data for commercial gain, WISeID empowers individuals and organizations to remain fully in control of their digital presence, enabling them to attach trusted attributes to their online persona with autonomy and consent.
In addition, enterprises can now also deploy WISeID corporate accounts, giving administrators centralized control over employee and customer identities while streamlining the management of digital signatures. By merging WISeID and SEALCOIN and embedding them within a quantum-resistant architecture, WISeKey is pioneering a universal decentralized identity ecosystem for both people and objects, ensuring trust, security, and digital sovereignty. This milestone reflects WISeKey’s mission to empower individuals and businesses to protect their digital lives and operate with confidence in an increasingly connected, and soon a quantum-powered world.
