   4. Utilizes PixelPass library to automatically decode uploaded QR codes for accurate credential retrieval.

3. Streamlined Credential Sharing:

   1. Inji Verify leverages OpenID4VP standards to simplify the process of verifying the verifiable credentials (VCs). Instead of embedding the entire credential within the QR code and with the OpenIDVP online sharing feature the QR code is embedded with a URL that points to a secure storage location like Inji Web or any platform adhering to OpenID4VP standards. This reduces the size and complexity of the QR code, making it easier to scan and share across devices, while still ensuring secure credential verification.

4. Docker Compose for Easy Installation:

   1. Inji Verify offers a streamlined installation process by supporting Docker Compose. This containerization tool allows users to quickly set up and deploy the application without complex configuration steps.

5. Validation and Verification:

   1. Upon scanning a QR code or uploading the QR Code, Inji Verify validates the authenticity and integrity of the credential data.

   2. Advanced algorithms and cryptographic methods ensure that the QR code has not been tampered with and consumes pixel pass library v0.5.0.

   3. Real-time verification provides instant feedback on the validity of the credential, giving users confidence in its authenticity.

   4. PixelPass library now supports decoding of CBOR-encoded QR codes, enabling Inji Verify to verify CBOR-encoded QR codes. However, CBOR encoding capability within the PixelPass library is still under development.

6. Credential Display:

   1. Valid credentials retrieved through QR code scanning or uploading QR codes are displayed securely within the Inji Verify portal.

   2. Users can view detailed information about the credential, including name, DOB, gender, expiration date, and any associated claims.

   3. The user-friendly interface provides a clear and concise representation of the credential data for easy verification.

7. Ease of Integration for Verifier Applications:

   The Inji Verify SDK- OpenID4VP- VP verification component enables developers to easily embed OpenID4VP- VP verification capabilities into their verifier (relying party) applications. This plug-and-play TypeScript component is designed for seamless integration with React + TypeScript applications, enabling robust Verifiable Credential verification using OpenID4VP standards.

   a) Modular NPM Package: The OpenID4VP component is available as a standalone NPM module, promoting modularity and simplifying integration. Developers can incorporate it into their projects without depending on the full Inji Verify repository. Comprehensive documentation (add link of the integration setup guide) is provided for installation, setup, and usage, ensuring a smooth integration process.

This flexibility empowers developers to accelerate their VC verification implementation with minimal setup, enabling faster time-to-market for digital identity-enabled services.

Note: The Inji Verify SDK- Scan / Upload component to enable developers to easily embed VC verification capabilities into their verifier (relying party) applications will be coming out in future releases! Stay tuned!

1. Generate QR Code based VP request for sharing credentials from wallet to Inji Verify for verification in different devices: The OpenID for Verifiable Presentations (OpenID4VP) standard introduces the VP Token, enabling end-users to present Verifiable Presentations (VPs) to verifiers via a digital wallet. In scenarios where the verifier and the user's wallet operate on separate devices, the process unfolds as follows:​

   1. The verifier formulates an Authorization Request, which is then rendered as a QR code. This QR code encapsulates a Request URI, allowing the wallet to retrieve the complete request data, thereby keeping the QR code concise.

   2. The user scans the QR code using their digital wallet (e.g., Inji Wallet), which fetches the Authorization Request data and prepares the requested credentials. Depending on the wallet's contents, the user can share all or a subset of the requested credentials.​

   3. Utilizing the vp_token response type and the direct_post response mode, the wallet securely transmits the VPs directly to the verifier's specified endpoint via an HTTP POST request. ​

   4. Upon receipt, the verifier assesses the authenticity and validity of the presented credentials. The verification results are then displayed within Inji Verify, providing immediate feedback on the credential status.​

This cross-device flow ensures a secure and efficient method for users to share their verifiable credentials across different devices, enhancing both flexibility and user experience in credential verification processes.

1. Backend Setup and Verification Mechanism : Inji Verify's backend supports robust and secure verification of Verifiable Credentials (VCs). The integration of the vc-verifier library facilitates server-side verification of VCs, accommodating both Ed25519 (Signature 2018 & 2020) and RSA (Signature 2018) cryptographic standards.To ensure persistent and reliable data storage, the backend has transitioned from an in-memory H2 database to a PostgreSQL database which enhances data durability.

2. Language Selection: User can choose from the listed languages for better usability so that the text description and VC result on the UI is displayed based on the chosen language . Inji Verify supports the following international languages: Portuguese, Spanish, French, English, Arabic, Khmer and the following Indian langauges: Tamil, Hindi, Kannada
