Security and Confidentiality concerns

[ROBERT-MCDOWELL]

I didn't find any whitepaper or proof that this new feature guarantees private data confidentiality and safety with 100% approved code that no third parties nor the browser itself will intercept barcodes and face data for themselves for resell or share it to illegal activities.

This repository only covers the specification of this interface, not how it may be implemented by a particular browser and the data protection features that browser implements. I can only speak for the Chromium implementation when I say that barcode detection is implemented using the APIs provided by the platform on which the browser is running, for example the Vision Framework on macOS and the BarcodeDetector API on Android.
