Inro

Inro is a revolutionary advancement in decentralized ID verification, offering a privacy-centric solution that enables individuals to prove their age without compromising personal information. This system is ideally suited for venues such as bars and rental services, where age verification is essential, but other personal information is unnecessary. The verification process is streamlined through a simple QR code scan, designed to be efficient and user-friendly.

Users generate a QR code using the Inro smartphone app, and when service providers scan this code, the user's age is verified using zero-knowledge proof technology. This process allows for age verification without disclosing any additional personal information, ensuring a high level of privacy and security.

Inro leverages the Sindri API to achieve efficient and secure generation of zero-knowledge proofs. Utilizing the Sindri API significantly reduces the time required to generate zero-knowledge proof proofs, and Noir, a tool for developing proof logic, ensures that only the necessary age information is verified. By harnessing Sindri's technology, Inro enhances its capability to provide reliable digital ID verification while maximizing user privacy protection.

How It Works

The process consists of four simple steps:

For Users:

1. Scan Your ID: Currently, the system supports only the MyNumber Card, a government-issued ID in Japan.
2. Show the QR Code: Generate and display the QR code through the Inro app for scanning.

For Verifiers (e.g., Bar Owners):

1. Scan QR Code: Use the Inro system to scan the presented QR code.
2. Check Verification Result: Verify the age without accessing any other personal information.

Future Prospects

Inro is poised to transform various aspects of digital identity verification, holding significant implications for both users and businesses:

1. Automated Age Verification in Bars: Simplifying the age verification process enables bars and similar establishments to operate more efficiently by ensuring compliance with age restrictions without the need for manual checks.

2. Enhanced eKYC Process: The automation of the eKYC (Electronic Know Your Customer) process can significantly reduce initial setup costs, ranging from hundreds of thousands to millions of yen. Additionally, it eliminates the waiting times for account openings, such as securities accounts that previously required manual verification, and reduces the labor costs associated with verification tasks.

These applications are especially important as they not only pave the way for more secure and private transactions in the digital age but also address the growing need for digital identity management and privacy protection in society.

Inro was constructed with a paramount emphasis on privacy, security, and user-friendliness. The backend of Inro taps into the power of the Sindri API for the generation of zero-knowledge proofs, notably utilizing the Noir proving system to craft the logic behind age verification. This approach ensures that only indispensable information, such as a user's age, is authenticated while safeguarding other personal details from exposure.

For the frontend, Inro is engineered using modern JavaScript frameworks, with React Native specifically chosen for its ability to deliver a seamless and intuitive user experience across both iOS and Android platforms. This choice underscores Inro's commitment to accessibility and efficiency, allowing users to interact with the system through a smartphone app where they can generate a QR code for age verification.

To facilitate the scanning of NFC cards, Inro leverages Expo's Native Modules feature, integrating advanced functionality into the app without compromising on its cross-platform compatibility. This integration not only enhances the system's usability but also showcases Inro's innovative approach to leveraging cutting-edge technology for practical purposes.

A particularly innovative feature of Inro is its capability to offer reliable age verification while ensuring privacy remains intact. The synergistic combination of Sindri's adept proof generation and Noir's specialized logic, supplemented by the application of React Native and Expo's Native Modules for NFC card scanning, positions Inro as a distinctive and invaluable asset in the realm of digital identity verification.
