Mobility

Overview

Current challenges

The mobility sector is undergoing a deep and wide transformation with mobility providers such as DriveNow, Car2Go, Sixt Share, Uber, and Lyft all experiencing significant growth driven by the changing mobility patterns of young adults, who are largely reshaping the industry.

Today, centralized mobility service providers go-to-market strategy is based on proprietary and customized service offerings. As a result, customers are forced to create multiple accounts with each mobility service provider, plus any public transportation accounts they might need in their own city and possibly other cities.

Furthermore, to process the mobility service for their users, providers need to integrate various backend services like onboarding, verification, authentication, payment, and settlements. To meet identification and authentication regulations, each service provider also needs to implement a KYC mechanism.

The importance of trust

In B2C relationships, the customer needs to trust the service provider, not only to use the service but also pay for it. Trust is also required in B2B relationships between mobility service providers and their providers of mandatory functional capabilities:payment, user identification, etc.

Without knowing the business partner (KYBP) and customer (KYC), business relationships cannot be entered into. The sector requires a much higher degree of agility and spontaneous trust than most, both structurally and in the user experience demanded by its younger, digital-native target customers.

Digital-identity-powered KYC and KYBP

One key objective of a blockchain-driven solution for these trust issues is to automate the verification and authentication process between business partners.

To enable participants to discover mobility service offerings and enter into contracts with a business partner in a seamless and automated way, it is paramount that all involved parties have a unique, verifiable, and addressable digital identity with associated credentials that can be verified by third parties. The digital identity and its associated verifiable credentials are stored and managed by the identity holder in wallets. Credentials for digital identity holder are issued by trusted organizations or enterprises, so called issuers.

Only in this way, humans, enterprises and machines can find their match online, verify its identity by resolving the issuers credentials and to enter a business transaction.

Built on Self-Sovereign Identity (SSI) principles, Spherity enables a comprehensive and end-to-end user experience that gives the holder identity control over its own data.

Identity verification and credential based trust

All participants in an open mobility ecosystem need to have unique, addressable, and verifiable identities. Participants can be humans, enterprises, and machines: vehicles, trains, etc.

Human identity

Based on the user ́s digital identity, the service provider or another interacting entity like a vehicle, needs to verify whether the digital identity is really the person requesting a service or access to a vehicle.

Spherity´s identity wallet for humans allows users to store issued credentials and to present them to verifiers in a privacy-preserving way. The user can store credentials such a picture for biometric authentication, driving license ID, date of birth, address, etc. in an identity wallet. These credentials can be issued directly to the wallet by trusted governmental organizations, or by identity verification providers. As the DIDs of either kind of issuer are publicly resolvable, the origin of credentials can be cryptographically proven without the need to contact them in any way.

Spherity´s identity wallet capabilities for humans can be either integrated with a SDK into existing mobility applications or used as a standalone app on a mobile device.

Enterprise identity

Like humans, legal entities like enterprises or organizations need a digital identity, that can be used to enter legally binding contracts or to issue credentials. In B2B relationships, the involved mobility service and functional capability providers need to be able to automatically prove whether the other party is a valid company or not.

Spherity offers identity wallets for enterprises that enable automated interoperability. Based on Know Your Business Partner (KYBP) processes, enterprises can store credentials that are issued by corporate registries or trusted organizations. These credentials are fundamental to interacting with previously unknown business partners.

The enterprise identity wallet API can be consumed by existing systems. Additionally, Spherity offers an identity wallet web application to manage delegated digital identity functions, such as role-based access controls or fleet management of automotive identities.

Machine (vehicle) identity

In the context of mobility, humans and enterprises need to interact with vehicles. Today, vehicle identities and their associated data are siloed in multiple backend systems of OEMs or mobility service providers.

To make this data accessible for mobility service providers and to link relevant data to transactions, Spherity uses an identity wallet to store different kind of data as credentials on the digital vehicle identity.

Verification

For users, the optimum experience is to run through the identity verification process only once, reusing the verification as long as their credentials are valid.

The participants in an open mobility ecosystem need to be able to verify each other based on the digital identity on the network. This verification process has to be automated, ideally in the span of a few seconds. This requires the digital identity to be able to present some form of proof that the driver holds a valid driver's license or that the vehicle is registered.

Operations

Today, mobility service providers have their own apps with permissioned identity management that is not designed to be interoperable. Vehicle identities are managed in permissioned backend systems and enterprise/ governmental organization identities are only globally verifiable by using private Ids of registry service providers.

Hence, a meta infrastructure layer to manage digital identities for humans, vehicles, and enterprises is required.

Design requirements for digital vehicle (machine) and enterprise identities differ. For both, Spherity is offering solutions within the decentralized identity management services. Spherity offers a mobile identity wallet for humans and a cloud based identity wallet management solution to manage decentralized enterprise and vehicle identities.

Summary

For the Mobility Blockchain Platform, Spherity contributes an Open Source Identity Wallet SDK for humans. This enables mobility service providers to integrate DID Management, Verifiable Credential, KYC, and payment functions into their existing applications.

In collaboration with Daimler and other startups, Spherity is contributing on the Mobility Blockchain Platform to facilitate the open ecosystem for the future of mobility. Platform capabilities enable mobility service providers to expand their service offering. By using this infrastructure, seamless multimodal transportation and other innovative service offerings can be realized.

Further details on capabilities, business models and the open ecosystem will be published soon.
