Whether this suits your team

Why this fits you

This organisation declared winners on 10 problem statement(s) in SIH 2025. It has awarded 4 joint winner(s), so it sometimes splits a prize between two teams.

Not decoded yet

We have this problem statement but have not run it through our decode pass. The government’s own description is below, unchanged.

What they'll ask you

Generated from the brief's own wording and the competition's published rules — never from a guess about what this ministry prefers.

We have not run our decode pass over this one yet, so these are the questions asked of every team rather than questions about this problem statement. The organisers’ own description is on this page, unchanged.

Has any part of this been shown at a previous event, hackathon or college project?
The guidelines are explicit: your solution must not have appeared in any previous event or programme, of any sort. A recycled project is what a team under time pressure reaches for.
Where does your data come from — a published source, one you collect, or one you generate?
No dataset is attached to this problem statement, so sourcing it is part of the work and nobody told you that.
Why not use what already exists? Name the closest thing to this that is already running.
A team that has not named the alternative themselves is answering this for the first time in the room.

1 more— the ones a panel gets to if there is time

Which single thing will you demonstrate end to end, start to finish, with nothing skipped?

The data

What the organisers attached, and what the brief assumes you can get.

Dataset from the organisers: None attached
Does the brief need data?: Nothing in the text says it depends on a dataset we would have to find.

Also from Ministry of Home Affairs

Same organisation, same year. Reading two of theirs tells you more about what they care about than reading one.

# Context: India's Smart India Hackathon 2026

I am on a student team entering SIH 2026. Problem statement SIH26231, set by Ministry of Home Affairs.
Its official title, word for word: "Digital Companion for Field Drug Testing"
Theme: MedTech / BioTech / HealthTech. Category: software.

## The organisers' full description, verbatim

<p><strong>Background:</strong></p>

<p>

Field drug-testing kits currently in use rely on visual interpretation of a colour-change reaction. This makes results subjective, difficult to standardise across officers, and leaves no verifiable record that a test was actually conducted at a given place and time. As a result, field test outcomes cannot presently be relied upon as documentary evidence.

</p>

<p><strong>Description:</strong></p>

<p>

Participants are to build a mobile application that works alongside existing colorimetric field-test kits (no new hardware).

</p>

<p>The application should:</p>

<ul>

<li>

Capture an image of the test result using the device camera, using a reference colour card in-frame for lighting calibration.

</li>

<li>

Automatically classify the result against a defined set of outcome categories (e.g., positive, negative, inconclusive).

</li>

<li>

Generate a tamper-evident digital record of the test, capturing timestamp, GPS location, and an operator identifier, together with a cryptographic hash of the captured image.

</li>

<li>

Maintain a simple, searchable log of tests conducted.

</li>

</ul>

<p><strong>Expected Deliverables:</strong></p>

<p>

A working mobile/web application prototype demonstrating image capture, automated result classification, and generation of a signed digital record.

</p>

<p><strong>Note to Participants:</strong></p>

<p>

The output of this application is a presumptive field-test result and a supporting digital record; it does not replace laboratory confirmatory testing.

Note to Participants:

The output of this application is a presumptive field-test result and a supporting digital record; it does not replace laboratory confirmatory testing.
## Constraints that are not negotiable

- The judged build is a prototype demonstrated in roughly 36 hours by students, not a product.
- A jury evaluates it against this problem statement's own wording, not against general merit.
- We submit on sih.gov.in; the problem statement number and title above must match exactly.
- Your solution must not have appeared in any previous event or programme, of any sort.

## What I want from you

1. Who actually has this problem in India, and what they do about it today.
2. What already exists — government systems, open-source projects, published research — that we should not rebuild.
3. For each item under 'what the brief never says', what the realistic answer is likely to be and how I could verify it.
4. The two or three things about this domain that a student team would get wrong without local knowledge.
## How to answer

- Everything above between quotation marks is the organisers' own wording. Treat it as the requirement.
- Do NOT invent requirements the brief does not state. If something matters and is not stated, say so and ask me, rather than assuming.
- Where you are inferring rather than reading, mark it as your inference.
- Do not guess what this ministry wants from its name. Its wording above is the only evidence.
