Here’s a detailed protocol reverse engineering paper: https://arxiv.org/pdf/2103.02282.pdf My guess would be that you, as the tag owner, locally store the master beacon key and can use it to derive key required to decrypt received beacon payloads for your own tags. You can then filter out your own and approximate how many others (which you cannot link over time) you permanently see. If it is more than one most of the time, you’re probably tagged without your consent.
