zkMe

zkMe develops a platform that upholds compliance standards in through Identity , aligning with principles of decentralization and privacy. The platform focuses on constructing a decentralized Identity , facilitating secure on-chain credential verification while preserving user privacy. By leveraging , zkMe enables verification and other credential-related services securely and anonymously. [1]

Overview

Founded in December 2022, zkMe Technology Limited develops Identity solutions for , enabling compliance and privacy through . Their Identity allow users to prove eligibility without revealing their Identity, bridging trusted credentials from traditional finance and the internet to ecosystems. This infrastructure supports secure, permissioned for institutions and users, ensuring data privacy and control over digital identities. [1]

On May 29th, 2023, zkMe closed a $2M pre-seed round with participation from , Spartan Group, CMS Holdings, , NGC Ventures, and Arkstream Capital. [2]

Technology

zk-SNARK

zkMe employs Succinct Non-Interactive Argument of Knowledge (zk-SNARK) technology to create proofs () that convey the Holder's identity without revealing sensitive data. These proofs run directly on the Holder's device, providing only anonymized results (yes/no statements) to Verifiers. This strategy enhances privacy and security by limiting data exposure and ensuring sensitive information remains confidential. [3]

Key tools for zkMe's implementation include SNARK JS and Circom. SNARK JS, a JavaScript library, handles generation and verification using various proof systems like Groth16 and PLONK. Circom, a domain-specific language (DSL), facilitates the creation of circuit constraints for , enabling developers to write constraints efficiently and generate seamlessly. [3]

zkMe utilizes the Groth16 algorithm, which necessitates a trusted setup to generate a common reference string (CRS) for each statement or circuit. Once established, this CRS can prove various statement instances over the system's lifespan. The Groth16 setup entails a multi-party computation ceremony to ensure system security, relying on at least one honest participant for its integrity. [3]

zkMe Architecture

wiki

zkMe App

The zkMe App is a secure, decentralized SSI wallet that uses MPC cryptography to store and manage anonymized identity information, including VCs from trusted entities. This allows for identity or attribute proof without revealing personal data. MPC distributes private keys across multiple devices or to reduce unauthorized access risk. The app includes OCR and facial recognition for mobile credential verification, enhancing security, and limiting data sharing. Users are screened against criminal, terrorist, or PEP lists to identify potential risks. [4]

Verification proofs, in the form of Soulbound Tokens (SBT), are minted from the SSI wallet and accessed via the zkMe App or Widget onto the user's asset wallet, which is typically self-custodial and used to interact with web3 dApps. If a user participates in multiple chain ecosystems, an SBT copy is minted for each to ensure a seamless experience. zkMe uses zk-SNARKs to generate anonymized Zero-Knowledge Proofs (ZKPs) representing the user's identity without disclosing sensitive data, ensuring privacy and security. [4]

zkMe Widget

The zkMe Widget is a JavaScript SDK that enables developers to integrate credential verification features into their applications, providing libraries and APIs for interaction with the zk-credential network. Designed for desktop browsers, it allows seamless user verification through the user interface and offers mobile QR codes for secure interaction with services. The zkMe SDK provides a user-friendly verification method, enabling verifiers to validate presented proofs (SBTs in the user's asset wallet) via the zkMe web API, smart contracts, or by prompting users for new proofs through a pop-up window. [4]

zkMe Dashboard

The zkMe Dashboard is designed for user eligibility checks, allowing verifiers to create "Verification Profiles" with specific business requirements like age or geographic restrictions. It offers tools for streamlining processes, customizable verification criteria, analytics, and reporting. Configurable API keys enable developers to integrate their with the zkMe Credential Network, ensuring compliance and a smooth user experience. [4]

zkMe OpenAPI

The zkMe OpenAPI allows developers to integrate credential verification processes into their applications, supporting secure user interactions and compliance with privacy standards through RESTful services. It offers API documentation for and KYT procedures, including endpoints for checking API status, compiling user lists, accessing information, managing address labels, and conducting risk assessments and transaction analyses. The OpenAPI provides tools for authentication using merchant numbers and API keys, detailing request structure and rate limitations to maintain system integrity and performance. [4]

zkMe zkVault

The zkMe zkVault is a Verifiable Data Registry that utilizes IPFS-based decentralized storage to prevent single points of failure and unauthorized access. Single within a Holder's SBT are stored for proof reusability and tamper resistance. When required by law, additional threshold encryption is used for raw identity document encryption, requiring multiple parties for encryption and decryption, enhancing security. Original identity documentation is stored with 3-out-of-3 threshold cryptography and split private keys to ensure maximum privacy and regulatory compliance. [4]

zkMe Smart Contracts

zkMe developed smart contracts for decentralized verification, allowing the protocol and Verifiers to process verifications autonomously. zkMe Mint and Delegate contracts mint original and delegate copies of DIDs onto Holder's . zkMe Verify and Certify contracts enable Verifiers to interact with the zkMe network and request the minting of a special SBT copy for legal data access if necessary. These functionalities are also accessible through zkMe APIs for non- native Verifiers. [4]

  • The zkMe Mint smart contract anchors verified credentials and their anonymized presentations on-chain.
  • The objective of the zkMe Delegate Smart Contract is to provide copies of the user's on-chain Identities across the chain ecosystems where the user is active.
  • The zkMe Verify & Certify Smart Contract (ZKMEVerifyUpgradeable) serves multiple functions, including verifying users' eligibility for services and meeting data recovery obligations to comply with regulatory requirements. This smart contract is activated when a decentralized application (dApp) detects a Soulbound Token (SBT) asset in a Holder's wallet.

zkKYC

zkMe zkKYC empowers users to verify their identity to a service provider without disclosing personal information, enhancing privacy and security compared to traditional eKYC solutions. This approach aids service providers in meeting regulatory obligations while mitigating the risks associated with data breaches, identity theft, and verification expenses. [4]

In the ecosystem, traditional processes can be challenging to implement due to their reliance on collecting and storing personal data, which conflicts with the principles of decentralization and data autonomy. However, -based offers a solution by allowing businesses to verify users' identities without compromising their privacy or the decentralized nature of the ecosystem. This approach addresses key business requirements, including privacy protection, regulatory compliance, security enhancement, efficiency improvement, and user experience enhancement. [4]

With -based , businesses can verify users' identities without requiring them to disclose personal information, thus safeguarding their privacy. Moreover, it enables compliance with regulatory requirements such as and regulations while maintaining the decentralized nature of the ecosystem. By enhancing security and reducing the risk of fraud, -based contributes to a safer environment for users and businesses. Additionally, it improves efficiency by streamlining the identity verification process, ultimately enhancing the user experience by providing a seamless and user-friendly interaction with applications and services. [4]

Self-Sovereign Identity (SSI)

Self-Sovereign Identity (SSI) presents a novel approach to address privacy concerns and identity misuse by granting individuals full control over their digital identities, unlike traditional systems dominated by organizations. With zkMe's SSI model, users can create and manage verified digital IDs or credentials within a secure digital wallet, ensuring sole ownership and control. This system allows users to selectively share data, determine recipients, and set expiration periods, enhancing privacy and control. Unlike conventional eKYC methods involving PII sharing, zkMe utilizes to generate mathematical attestations about credentials without exposing actual data. For example, zkMe users can verify age eligibility without disclosing birthdates or other sensitive PII, ensuring privacy while meeting verification requirements. [5][6]

MeID

The "one face, one digital identity" principle helps prevent automated scripts and Sybil attacks by using zkMe's facial recognition for identity verification. This process assigns each user a unique digital identity (DID), making it difficult for malicious actors to create fraudulent accounts. This method ensures businesses interact only with legitimate human participants, protecting them from the risks of inauthentic entities. [7]

CKKS Homomorphic Encryption

The CKKS algorithm, proposed by Cheon et al. in 2017, is a fully homomorphic encryption (HE) scheme designed for encrypted computations involving complex and real number data. It offers high computation accuracy and minimal ciphertext expansion, making it widely used in homomorphic encryption. This scheme protects users' facial feature data using homomorphic encryption during registration, where facial features are extracted with liveness verification, encrypted, and uploaded to the server. The server compares these encrypted features and sends back a similarity ciphertext for decryption and verification. If features are unregistered, the DID identifier and encrypted facial features are stored to complete registration. Homomorphic encryption allows secure computations on encrypted data, while liveness verification prevents fake account registration using others' photos, ensuring user privacy and secure DID creation. [8] wiki

MeScores

zkMe's identity allows users to bring personal data, like credit scores and social network statuses, to the . protocols can then use this data to create tailored features, such as determining loan eligibility in or recommending content on social networks. This enables a more personalized and efficient digital experience for users. [9]
