The Personal Data Ecosystem

Where We’ve Been. Where We Are. Where We’re Going.

The personal data ecosystem is evolving from systems largely organized around institutional control toward the possibility of more balanced relationships, in which people exercise meaningful agency over their identities, information, knowledge and digital interactions. Here is how we got here, where we are, and where we could go.

Stage 1 · Up to 2000 · What Was

The organization-centric approach

Data treated as a tool of social engineering and an enterprise asset.

The web, then mobile phones, then social platforms made it possible to connect almost anyone to almost anything. To pay for it, much of the industry turned to advertising, and advertising turned to data: what people searched, bought, read, watched, where they went and who they knew.

Organizations built the infrastructure that carried that information, wrote the terms that governed it and kept the records. Accounts were issued by the organization; the data lived in its systems; decisions about it were made on the person’s behalf. Shoshana Zuboff named the economic logic that grew from this surveillance capitalism: claiming human experience as raw material for predicting, and shaping, behaviour (Zuboff, 2015, 2019).

These systems also created enormous value: free services, connection across distance, convenience, personalization, and much of the innovation of the last 30 years.

Stage 1 · Up to 2000 · The organization-centric approach

Organizations, at the centre

  • Issue the accounts
  • Collect and keep the data
  • Write the terms
  • Make the decisions

Data: searches, clicks, location, purchases, contacts

Free services, ads

One way, mostly

People

You

An account at each organization, and terms to accept. Little that is your own.

Between organizations: data brokers, ad networks and trackers, buying, selling and combining profiles.

Key takeaway: organizations built, and largely controlled, the infrastructure and relationships through which personal information flowed.

Go deeper: how it works, and the argument

The machinery. Tracking codes and cookies follow people across sites; profiles are built from what they do; data brokers combine those profiles with records from many other sources and sell them on. The U.S. Federal Trade Commission opened a study of the data broker industry in 2012 (see the References).

The argument. Zuboff (2015) first set out surveillance capitalism in an academic article, then in a book (2019). Her account is influential and contested: critics question how well behaviour can really be predicted and shaped, and how new the logic is. Here it names one powerful economic logic within the ecosystem, not the whole of it.

The ideas that pushed back are as old as the problem: the glossary traces them from 1890, and the ecosystem map shows who tried to build alternatives.

Stage 2 · 2000 to 2025 · What Is

An ecosystem in transition

The emergence of human agency.

That logic hasn’t gone away. Platforms, data brokers, advertising technology, tracking and profiling are still central to the digital economy, and AI adds a new appetite for data, and new ways to use it.

At the same time, another way of working has grown up beside it: the people-centric approach. It isn’t one product or one idea. It is many, at very different stages:

ApproachWhat it doesWhere it stands
Personal data stores and PIMSKeep your information where you control itEmerging products exist; most early ones have closed
Self-sovereign identity (Allen, 2016), identifiers and credentialsIdentifiers and proofs you hold and presentEstablished standards W3C DIDs (W3C, 2022) and Verifiable Credentials (W3C, 2025)

Established a published standard, law or tool in wide use · Emerging specified or built, not yet widespread · Experimental drafts and early builds · Aspirational an idea not yet built. Each protocol’s status was checked on 8 November 2026: see Protocols and standards.

Stage 2 · 2000 to 2025 · An ecosystem in transition

Organizations

Private

Companies, shops, platforms, banks, employers, AI providers

Public

Governments, agencies, schools, health services

The traditional exchange, still dominant

Data: searches, clicks, location, purchases, contacts

Free services, ads

The new exchange, emerging

Consent and your own terms

Services, credentials and receipts

People

You, with tools of your own

Still between organizations: data brokers, ad networks and trackers.

The two approaches now run side by side, like the dark Rio Negro and the sediment-rich Rio Solimões near Manaus, in Brazil: in the same channel for kilometres, distinct, influencing each other, not yet mixed.

Identity and data: a meeting of the waters. An orange river, the organization-centric approach (organizations lead the collection, management and use of data), and a blue river, the people-centric approach (individuals have greater agency over their identity and data), meet at a circled point: coexistence, negotiation and change. They flow on side by side: an evolving relationship. How will control and responsibility be shared? A conceptual illustration, not a timeline or prediction.

IdentityAccounts the organization issues: who you are is what it saysIdentifiers and credentials you hold and present, on your own terms
DataCollected, stored and used by the organizationHeld, shared, restricted and revoked by the person; organizations are guests
KnowledgeKept in the organization’s systems and vendors’ cloudsKept in formats the person controls, so any tool or AI can use it and none can lock it in
AgencyExercised on the person’s behalfExercised by the person, increasingly through their own AI agents and twins

Key takeaway: organization-centric systems remain dominant, but people-centric alternatives are increasingly viable. The transition is neither complete nor inevitable.

Go deeper: the original sketch, the river, and who has tried
A hand-drawn map of two rivers meeting: an orange river labelled 'Organizational-centric approach' and a blue river labelled 'People-centric approach' join, with a red circle at the confluence marked 'We are here'. They run side by side, 'measured in years', toward a white stretch labelled 'What does the future hold?'.

Who has tried. The ecosystem map lists 105 organizations and initiatives since the 1990s: 49 are active today, 35 have shut down, 7 were acquired and 14 we can’t confirm. Many people-centric ventures failed for want of a business model, or of organizations willing to meet them halfway.

The standards behind each approach, with their status, are on Protocols and standards.

Stage 3 · 2025 onward · What Comes Next

The rise of empowerment tech

Humans and AI with a seat at the table.

Picture an ecosystem in which you can see who holds what about you, set your own terms, prove what you need to without revealing more, take your information and knowledge with you, and let an AI agent act for you only within limits you set, and withdraw them.

That doesn’t mean organizations disappear, or that you must keep all your data yourself. Much of it will stay with the organizations that use it. What changes is the relationship: your authority reaches across the systems that hold your information, through standards that let your identifiers, credentials, terms and agents work everywhere. Bodies such as the W3C and IEEE are writing those standards, and MyData Global’s Declaration 2.0 (MyData Global, 2026) sets out the aim: a world where people have ability, agency, safety and protection, and understanding and control.

Stage 3 · 2025 onward · The rise of empowerment tech

Organizations

  • Hold what they need, under terms you can see
  • Ask, and record the answer
  • Send receipts and credentials back
  • Earn trust, and keep creating value
  • Many keep their old methods too, in parallel, for some time

The traditional exchange, still running

Data: collected, kept and used

Services, ads and offers

The new exchange, alongside it

Agreements: terms, consent, credentials, receipts

Your AI agents, within limits you set

  • Agents negotiating on your terms, at scaleAspirational

The traditional approach still exists, and will. We are where the two rivers meet. The work now is to find the equilibrium in which organization-centric and people-centric approaches co-exist. The aim isn’t to remove organizations or commercial value. It is relationships that are more transparent, accountable, voluntary and good for both sides. The Identity Nexus™ is a test of that: individuals, private organizations and public organizations each want value, insight, efficiency and effectiveness, and safety and security. Is each party’s value in proportion to the risk it carries, and does the exchange add to the commons rather than draw it down?

We are at a crossroads

Which path will you choose?

We are at a crossroads One road reaches a fork where a person stands. Up and to the right, a red path leads to dystopia. Down and to the right, a green path leads to a utopia that won’t scale. Straight ahead, a wider blue path leads to the Identity Nexus, three overlapping spheres. Dystopia Orwell was an optimist Utopia that won’t scale The Identity Nexus™ Identity Praxis, Inc. © 2023
  1. Further the organization-centric approachToward a dystopia, where Orwell was an optimist (Orwell, 1949).
  2. Lean only to the people-centric approachToward a utopia that won’t scale.
  3. Take the middle pathThe two come together, and we strive for The Identity Nexus™.

Key takeaway: people should have meaningful agency, organizations should earn trust, and value should flow through relationships that benefit both.

Go deeper: the standards, and the case for sharing well

Established: W3C Decentralized Identifiers (DIDs) v1.0 (W3C, 2022) and Verifiable Credentials Data Model v2.0 (W3C, 2025); IEEE 7012-2025 (IEEE, 2025), machine-readable personal privacy terms. Emerging: did:webvh, Solid, Portable Web Spaces, the Model Context Protocol and Agent2Agent. Experimental: the Human Context Protocol, at draft 3. Each is on Protocols and standards, with its maintainer and status.

Sharing, with rights protected. The OECD’s 2021 Recommendation on enhancing access to and sharing of data (OECD, 2021) sets out principles for getting the benefits of data while protecting the rights of people and organizations: the people-centric approach is about how data is shared, not whether.

4 · The Relational Nexus™

Human agency at the center

Every piece of information, product and decision sits in a web of relationships: with people, organizations, technology, regulation, society and culture, and now with non-human intelligences, the AI agents and twins that act for us and for others. We call that web the Relational Nexus™. The Identity Nexus is one part of it: the part concerned with the value and the risk of sharing information.

At its centre is human agency: your ability to act, on your own judgment, in your own interest and in your relationships.

The Relational Nexus™PeopleOrganizationsTechnologyAI agents and twinsRegulationSociety and culture

Human agency: you can

  1. Understand your environment and your choices
  2. Make informed decisions
  3. Manage your identity and information
  4. Create, organize and apply knowledge
  5. Build and keep relationships
  6. Grant, delegate, limit and revoke authority
  7. Take part in exchanges, and gain value
  8. Act yourself, or through AI agents you authorize

Agency is not the same as…

What it meansHow it relates to agency
ControlDirecting what happens to somethingA means to agency. You can control data and still have no real choice.
PrivacyAppropriate flows of information about youA condition for agency. Agency includes choosing to share.
OwnershipA property claim over somethingOften unclear for data. Agency doesn’t depend on it.
SovereigntyUltimate authority over yourselfThe principle. Agency is its exercise, day to day.

Agency doesn’t come automatically with new technology. A wallet you don’t understand, or an agent you can’t limit, gives you none. It has to be a design objective, for every system and every relationship.

Key takeaway: human agency is the point. Technology, standards and law are how we get there, if we design for it.

Go deeper: the frameworks

The Relational Nexus™, and its four areas of focus in Relational Technology Architecture™: AI; personal and organizational knowledge management; self-sovereign identity and data principles; and engagement. The Agency Line asks where AI does your work, and where you keep your agency and critical thinking.
