Giving to Research,
Without Ever Losing Control

You choose a pathology. You give only the data related to it. You revoke at any time. Cryptographic anonymization, blockchain proof, no pharma or insurer access.

V2 — available after V1 stabilization. Module strictly outside medical device scope.

Research Is Stuck Between Two Dead Ends.

Dead End 1

Hospital Silos Are Closed

Every university hospital keeps its data. Researchers spend months on agreements, sometimes years. The result: studies lack volume, results are delayed, treatments arrive later.

Dead End 2

Patients Are Absent From Decisions

When there is data, the patient is not consulted: their record leaves via framework agreements signed by their hospital. They don't know, don't choose, don't revoke.

We propose a third way: an explicit, granular, revocable patient contribution.

Four Steps. You, Every Time.

You Choose a Pathology

From the approved research programs displayed in your app: diabetes, Alzheimer's, cancers, rare diseases. Each program specifies the sponsoring laboratory, the objective, the duration, the data requested.

You Give Only What Concerns This Pathology

Not your full record: only the medical data related to the program (e.g. your glycemia and antidiabetic prescriptions, not your dermatology). Client-side filtering, before sending.

Data Is Anonymized Before Leaving

Pseudonymization, k-anonymity on identity traits (age bracket, region, sex), differential privacy on aggregates. Your passport and the researcher dataset are never linkable.

You Revoke at Any Time

One tap in the app. Data already integrated into a study is removed from the next recalculation. Enforceable blockchain proof — including in case of litigation with the laboratory.

Your Gift Comes Back to You.

This is not a one-way extraction. Every discovery from the cohort is reinjected into contributors' apps — new recommendations, more precise alerts, improved follow-up.

You Consent

Pathology donation opt-in, granular, revocable.

The Researcher Observes

Anonymized aggregated data, without identity.

A Result Emerges

New protocol, new alert, new correlation.

You Benefit

The benefit returns to your app: recommendation, follow-up, prevention.

This loop is also the key to MDMC's data moat: the more we learn, the better we serve you, the more you benefit — without losing sovereignty.

Three Layers So Nobody Finds You.

  • Client-side pseudonymization. Your passport identifier is replaced by a cryptographically derived pseudonym before sending. The researcher sees a random tag, not you.
  • K-anonymity on identity traits. Age by 5-year bracket, region (no municipality), sex. Any trait that would allow cross-referencing your identity is generalized.
  • Differential privacy on aggregates. The researcher cannot submit queries that isolate an individual. Calibrated noise protects edge cases.

Example of transmitted data

{

"subject_id": "7a3f…e2c1",

"age_range": "45-49",

"region": "Île-de-France",

"sex": "F",

"condition": "E11",

"hba1c": 7.2,

"meds": ["metformin"]

}

No name, no birth date, no municipality. The researcher sees a citizen, not you.

Not Promises. Contractual Clauses.

No Data Sale

Never. Written in our Terms of Sale. Labs pay to access cohorts, not to buy you.

No Pharma Marketing Access

Research data is not shared with commercial teams of laboratories. Verifiable contractual separation.

No Insurer Access

Insurers cannot buy access to our cohorts. Non-negotiable contractual clause.

Quarterly External Audit

An independent firm verifies every quarter that donation flows respect the framework. Public reports.

The Lines We Do Not Cross

Create Your Passport Today. Contribute Tomorrow. If You Want To.
