Sismo.io provides a single sign-on solution, Sismo Connect, that enables applications to access user data stored in a secure Data Vault using zero-knowledge proofs for privacy-preserving authentication. This technology allows for selective disclosure of anonymized personal data, facilitating secure interactions between users and applications without compromising user privacy.

Problem
Current single sign-on (SSO) solutions often lack privacy, requiring users to share personal data directly with applications, which can lead to data breaches and a loss of control over their information. Existing systems also struggle to aggregate and authenticate data from diverse sources, limiting the ability to create truly sovereign and user-centric applications.
Solution
Sismo Connect offers a privacy-preserving SSO solution that allows applications to request and verify user data without directly accessing the underlying information. Users aggregate their data in a personal Data Vault and selectively disclose anonymized pieces of information using zero-knowledge proofs. This approach enables applications to authenticate users and access necessary data while maintaining user privacy and control. Developers can integrate Sismo Connect with a few lines of code to build sovereign applications that leverage user data in a secure and privacy-centric manner.
Target Audience
The primary target audience includes Web3 developers building decentralized applications (dApps) that require user authentication and data access while prioritizing user privacy, as well as any application developers seeking a more secure and user-centric SSO solution.
Features
- Data Vault: A personal data aggregator where users store and manage their data from various sources.
- Zero-Knowledge Proofs: Enables users to prove ownership of data without revealing the data itself.
- Sismo Connect Request: Allows applications to request specific data from a user's Data Vault.
- Selective Disclosure: Users can choose which pieces of data to share with each application.
- Message Signature: Allows users to sign messages with their data, proving intent alongside data ownership.
- Offchain and Onchain Verification: Sismo Connect Responses and ZK proofs can be verified both offchain and onchain.
- TypeScript SDK: Facilitates easy integration of Sismo Connect into applications.
