Chapter 1: Introduction

By “understand how it works” I mean could you, if asked to do so, put together a presentation for managers and investors in your AdTech company or your brand’s advertising or privacy groups that can explain in moderate detail how it works today and how it currently is envisioned to work when the specification and the underlying systems are completed?

We are not going to get into flows or “connective tissue” for how the various pieces talk to each other (e.g. OHTTP) for now. We are going to build up the main static elements first, bit-by-painful-bit, exploring all the underlying concepts and technologies that reside within and drive the functionality of these “big pieces”. Then we will show how all the pieces fit together.

This will be a living document, so you can always check back in if you see a new term that I haven’t explained before to see if I define it here. Alternately, please use the comments section below to ask me to define terms here that you would find useful.

The previous post ended with a high-level diagram of the revised Chrome browser that is adapted for the Google Privacy Sandbox (Figure 1). In this article, we will explore in more detail the core products and services that form the browser side of the Privacy Sandbox. In the subsequent article, we will highlight each element in Figure 1 and explain how it supports/ties into the products and services that need to be delivered (Figure 2).
