The Global Centre for Risk and Innovation (GCRI)
The methods Digital Public Infrastructure relies on, the assumptions they carry and the limits of what they can show.
GCRI · In development · service level R0
The Digital Public Infrastructure methods page sets out the methods the platform relies on, among them digital identity and public digital systems, data engineering, interoperability and stewardship, and cybersecurity and cryptography, with their assumptions, validation and limits. Each analysis lists its assumptions and data, reports ranges and confidence beside central estimates, is checked against observations or other models, and states what it cannot show.
Fig.How a finding is reviewed before it is published. Design, not a record.
For methods and uncertainty, in GCRI's spatial-intelligence reading, the map opens on true-colour imagery, night lights and population density with true colour from NASA GIBS, framed on India; every other NASA layer, live feed and forecast waits in the layer list.
The interactive map needs JavaScript; the layer list and sources are below.

Layers and dates
| Source | Why it matters here | How it is reported |
|---|---|---|
| Exclusion data | Rarely measured | Survey evidence labelled |
| Outage data | Not always disclosed | Sources stated |
| Adoption | Registration differs from use | Both shown |
Each analysis lists its assumptions and the data it depends on.
Ranges and confidence are reported alongside central estimates.
Models are checked against observations and, where possible, against other models.
What an analysis cannot show is stated beside what it can.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Uncertainty quantification | Characterising and propagating the uncertainties in a model to state confidence in its outputs. |
| Sensitivity analysis | Repeating an analysis under different assumptions to show how much the result depends on them. |
| Model validation | Comparing model predictions with independent observations to judge fitness for a stated use. |
| Digital identity and public digital systems | Digital identity and public digital systems provide the means for people and organisations to prove who they are and access services online. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
