Digital passport with verified data provenance

Abstract

Systems and methods for accurately and securely assembling, storing, and leveraging travel data are provided. A method may include detecting a travel event of a user. The method may include recording the travel event in a travel map that is stored in a database. The travel map may be a temporal- and spatial-based record of one or more travel events of the user. The travel map may be stored as a blockchain ledger. The method may include tokenizing sensitive information associated with the user in the database, and calculating a hazard vector. The method may include updating, based at least in part on the hazard vector, a status index associated with the user, and providing the user and a system administrator access to the travel map and the status index. Access may be provided via an online portal configured to be viewed via an application running on a mobile device.

Description

FIELD OF TECHNOLOGY[0001]Aspects of the disclosure relate to digital systems. Specifically, aspects of the disclosure relate to secure digital systems with increased data accuracy.BACKGROUND OF THE DISCLOSURE[0002]Traveling may expose a traveler to hazards. Being exposed to the hazards may present a danger to the traveler. Being exposed to the hazards may present a danger to other parties aside from the traveler. The traveler and the other parties may be unaware of the exposure. The traveler and the other parties may be unaware of the danger presented by the exposure.[0003]Travel data may include travelling patterns associated with travelers. Travel data, however, is often inaccurate and not comprehensive. For example, a traveler may travel on one itinerary using one passport and a second itinerary using a second passport. Travel data based on one passport will be incomplete. As another example, an itinerary may indicate that a traveler traveled from a first country to a second coun...

AI Technical Summary

Benefits of technology

The patent is about a system that can accurately and securely collect, store, and use travel data. The system detects when a user moves from one location to another and records this information in a database. This information can be used to calculate a hazard vector and update the user's status index. The system uses a blockchain ledger to store the travel data, which ensures increased accuracy and security. The technical effect of the patent is to provide a reliable and safe way to manage and use travel data.

Problems solved by technology

Traveling may expose a traveler to hazards.

Being exposed to the hazards may present a danger to the traveler.

Being exposed to the hazards may present a danger to other parties aside from the traveler.

Travel data, however, is often inaccurate and not comprehensive.

Travel data, therefore, may lack important information.
