Stop Stockpiling Personal Data, Put Users in Control

Handling personal data means a heavy burden of collection, storage, consent, and breach response. MyID is DID-based identity and data infrastructure: users control their own data and submit only what's needed. User-held storage and selective disclosure cut the burden of holding personal data.

Why Now

Data Is Starting to Move
Around the User

A trend that started with MyData, users moving and controlling their own data, is spreading across healthcare, telecom, and every other sector.
At the same time, the more personal data an organization stockpiles, the heavier the burden of breach exposure, regulation, and consent management.

Problem

Solving the Burden of Personal Data

Problem
You Take On Personal Data Yourself
Storage risk

The more personal data you stockpile, the heavier the burden of breach incidents, fines, and lost trust.

Repeated collection and consent management

Every service collects the same information again and manages consent separately, and the cost adds up.

User-control requirements

Users can exercise a right to data portability, requesting that their data be moved or deleted, and institutions have to respond.

Tamper verification

You need to confirm received data is genuine and hasn’t been altered.

After adoption
We Restructure So You Don't Have To
Users hold their own data

Data sits in the user's own storage, so the institution never has to stockpile it directly.

Verify once, reuse everywhere

Information verified once is reused across services, so it never has to be collected fresh each time.

Users share only what is needed

Users choose only the fields a service needs, and requests to move or delete data are handled immediately.

Confirm authenticity instantly

Blockchain lets you confirm instantly that data is exactly as originally issued.

Features

A Structure That Never Stockpiles Personal Data

Data stays under the user's control, and services verify only the facts they need.

  • PDS · Personal Data Store

    Puts data under user control and reduces the storage burden for institutions.

  • BFS · Distributed Storage

    Splits large data across multiple locations, retrievable anytime, tamper-free.

  • Selective Disclosure (ZK)

    Proves only what's needed, like adult status instead of a birth date, hiding the rest.

  • MyID Wallet · API

    Issues, stores, submits, and verifies identity and data via a simple API, no separate app required.
