Short Answer Question

The purpose of the application is to provide a universal and decentralized user verification solution with cross-verification capabilities that allows user information, especially information related to user documents, to be securely shared and verified between enterprises.

Cross-verification refers to a system in which one entity (such as a company) can request information from another entity that verifies the identity of a specific user. This ensures multi-party verification before sensitive user information is shared.

The system uses two main types of user identification information: (1) traditional identification documents such as passports, driver's licenses, and utility bills, and (2) biometric data such as fingerprints, iris scans, and facial recognition data.

DUID refers to "Digital Unique Identifier" and is used in the system to create a unique, verifiable identity for each user on the blockchain or trust tool.

The system leverages the decentralized and tamper-proof nature of the blockchain or trust tool to securely store and verify user data. Each user's verified document is associated with their DUID and stored on the blockchain, creating a secure and auditable record.

Company A can request access to a verified user document held by Company B by sending a request to the trust tool that specifies the user and the required information they wish to access. The system then prompts the user to approve or deny the request.

The user plays a vital role in granting access to verified documents. Before any access is granted, the system notifies the user of the request and requires the user to explicitly consent to share their information.

The "Receive Verified Document Component" is responsible for receiving verified documents associated with a user from an entity (such as a company or organization). These documents can include identification documents, proof of address or any other relevant documents used to verify the identity of the user.

The system utilizes biometric data to enhance its security measures and provide a reliable method of user authentication. It allows the use of fingerprint scanning, facial recognition or other biometric methods to verify the identity of users and authorize access to their data.

In addition to blockchain, other distributed ledger technologies such as Hashgraph, DAG (Directed Acyclic Graph) and distributed databases can also be used in this system to provide a secure and decentralized data management solution.
