AUTHENTICATED MODIFICATIONS OF MULTI-PARTY LEDGER DATA DURING USER CONNECTIVITY VIA IN-FLIGHT SYSTEMS

A central computing platform provides users with control over multi-party information involving third-party services during different stages of a travel journey, or while users are provided with data connectivity via different networks or systems. The central computing platform provides a digital ledger on which the multi-party information is recorded. Recording of the multi-party information, as well as modification thereof, requires authentication of each party as well as input (e.g., approval) by the computing platform. The central computing platform can be communicatively coupled with local networks, such as cellular networks, as well as mobile platforms or in-vehicle connectivity systems to which user devices can be connected. As a result, the central computing platform is involved in generation, recording, modification, and fulfillment of multi-party arrangements between users and third-party services.
