Go.cam - Age verification system

GO.cam offers a simple, easy-to-use application for verifying age online. With just a few clicks, it allows to verify the age of the person who wishes to access certain sites restricted to minors.

Two methods of age verification are available : facial recognition (selfie) and ID documents verification (ID card, passport, or driver's license).

For the selfie verification, GO.cam utilizes the smartphone camera or computer webcam to assess the user's age through artificial intelligence. If the detected age is too close to the legal age, another verification method is suggested.

GO.cam is certified 🏅

We are constantly working closely with regulators from many countries to certify GO.cam.

Authorities that already certified us:

• Central Authority for the Supervision and Protection of Minors on the Internet in Germany
• Age Check Certification Scheme

ASACP recommends Go.cam as a solution for protecting minors online by guaranteeing secure access to adult content.

Environment Variables

Copy the .env.example file and rename it to .env in the project's root directory. The service defaults to using port 3300 on localhost.

cp .env.example .env

Install

This project was developed using Nodejs v20, we recommend using a compatible version.

Clone this repository and install the required packages by running on the root the of the project the following command:

npm install

Run

After the installation of the packages you should be able to run the project in development or production mode. The only difference between them is the watch parameter (watches for any file changes on the backend and restart the nodejs process when a detection is made) which is enabled for the development version.

To run the project in development mode run:

npm run startDev

To run the project in production mode run:

npm run startProd

By default the project will run on http://localhost:3300. Due to the fact that this project requires access to some features that are restricted to https (e.g. webcam access), we recommend you running it on localhost on your first run.

Example implementation

By running this project you will be able to go through both types of verification flows: using a redirect or a iframe overlay.

Additionally, we provide a standalone implementation of go.cam in various programming languages. Please check the example folder for more information about this.

A MIT license alternative for the example implementation code can be found inside this repository: https://github.com/Godotcam/goCamOpenSourceExamples.
