Current centralized data sharing infrastructures fail to provide a reliable, GDPR-compliant, and ethical mechanism to share data, thus, impeding the development of the flourishing data economy. Indeed, the future of technology and, consequently, the flourishing economy and society should be built on a paradigm of decentralization. This is known more widely as the Web3 movement, which is being celebrated as the future of the internet, and which seeks to endow everyday internet users with the capacity to have full control of their digital footprint. It aims to provide a trustless, secure, unmediated, and verifiable infrastructure that spreads control throughout the community, putting the individual at the center of it all. Aiming to tangibly implement this paradigm shift, decentralized data access control enabled by EcoSteer’s Data Ownership Platform, provides a key to a trustless, unmediated ecosystem of data exchange where all the players are rewarded for participating. This is achieved by means of EcoSteer’s patented Multicast End-to-End Encryption Scheme and Blockchain Smart Contracts. The former hands the control back to the data owner by protecting the data at the point of its generation. The latter provides a possibility for Data Owners to control visibility over third-party access to their data granularly and establish a 1-to-1 relationship with all the interested Data Users. Furthermore, Blockchain also enables a straightforward compensation mechanism for data sharing in exchange of goods and services, which is an enormous incentive and an imperative for a lively ecosystem of data sharing.

4. Data Visibility Control Overlay
A multicast end-to-end encryption scheme, the Data Visibility Control Overlay
(DVCO) assigns control of personal data visibility at its point of origin – any
IoT device
Data streams flow encrypted from the point of origin to the point of usage, where
they can be decrypted only with the explicit consent of the data owner, as
mandated by EU GDPR

5. Terms
is any individual or a legal entity, who is the rightful
owner of a specific set of data streams
is any stakeholder, who is interested in receiving data
streams for whatever purpose
is a component responsible for data sharing, privacy, and
security
is a data streams-generating device
is a destination/target of data streams

DVCO API provides the
driver with unilateral
control over personal
data visibility,
making on-board data
sharing GDPR
compliant by-design
DVCO Cloud allows the
driver to manage data
access with granularity
and at any time
Turns the Data Movement
Platform into a neutral
data exchange,
eliminating costs and
liabilities of consent
management
Participate in
multicast scenarios
where consent is
managed directly by the
driver
Each Data User
establishes a
disintermediated 1-to-1
relationship with
drivers
ONBOARD / VEHICLE OFFBOARD / CLOUD OFFBOARD / DATA USERS

20. • Leverages existing HTTP and HTTP(S) protocols
• Utilizes readily available data sharing infrastructure
• Requires a simple software upgrade
• Can handle massive workloads (IoT)
• Designed to offer horizontal scalability and high availability
