#Brussels - 30 January - Commons Hub Workshop on Identity and Disposable Identities "This Self Sovereign Identity is able to create hundreds to thousands of disposable identities, reversing the current situation. The ‘I’ in the heart of the web is no longer the object of outer nodes, now it sends a different identity to each node and each provider. Mostly it will send payability tokens to each provider (energy, connectivity, subscriptions) as they have no need for any personal information they just want to get paid. If you do not pay, a personal item can be disclosed, only fair. For institutional queries it can send accountability tokens, showing that responsibility is taken for an act. For example, Zero-Knowledge Proofs (ZKPs), a cryptographic method where one party proves a statement is true (like having enough funds) without revealing the actual sensitive data (like the amount or who sent it) and ZKCC by @Dyne.org "

#asknostr #ultrasound #DIY #nerds #help Been researching ways to create DIY minature ultrasound wave emitter for the 17-20 kHz range, looking for help or pointers to anything similar out there in the wilds... I wish to build an 'inaudiable to humans' wearable ultrasound generator for protection from digital microphones and recording devices. Range 1.5-3 meters away from wearer. I have found some Arduino projects for pest-control and sonography using their board but it seems their standard ultrasound distance measuring module does not go to the right ultrasound range I am seeking for this... Imagine having a personal ultrasound forcefield that emits static noise for microphone but not for anyone you are speaking with directly. Whatever I build is FOSS, ideally the device will use a generic ESP32 and some small speakers with the right piezoelectric crystals. Starting point for this rabbit hole:
