Picasso WASM

Lightweight Device Class Fingerprinting for Web Clients using the HTML5 Canvas.

This small library implements parts of the Google Picasso white paper in WebAssembly. It can be used to identify different device-classes and generate a unique fingerprint for them. It can't be used to identify individual devices.

For more information about how this can be used check the white paper.

Usage

npm install picasso-wasm

// these values could come from your server
const seed = 1234567890;
const rounds = 25;
const width = 500;
const height = 500;

import("picasso-wasm")
    .then(wasm => wasm.make_fingerprint(seed, rounds, height, width))
    .then(fingerprint => console.log(fingerprint))
