In some cases, devices can connect to 'edge' devices - gateway devices that run on your local network meaning you can process data without making a call over the Internet. This can be faster when you have a lot of data or a slow Internet connection, it allows you to run offline where Internet connectivity is not possible such as on a ship or in a disaster area when responding to a humanitarian crisis, and allows you to keep data private. Some devices will contain processing code created using cloud tools and run this locally to gather and respond to data without using an Internet connection to make a decision. -One example of this is a smart home device such as an Apple HomePod, Amazon Alexa, or Google Home, which will listen to your voice using AI models trained in the cloud, and will 'wake up' when a certain word or phrase is spoken, and only then send your speech to the Internet for processing, keeping everything else you say private. +One example of this is a smart home device such as an Apple HomePod, Amazon Alexa, or Google Home, which will listen to your voice using AI models trained in the cloud, but running locally on the device. These devices will 'wake up' when a certain word or phrase is spoken, and only then send your speech over the Internet for processing. The device will stop sending speech at an appropriate point such as when it detects a pause in your speech. Everything you say before waking up the device with the wake word, and everything you say after the device has stopped listening will not be sent over the internet to the device provider, and therefore will be private. ✅ Think of other scenarios where privacy is important so processing of data would be better done on the edge rather than in the cloud. As a hint - think about IoT devices with cameras or other imaging devices on them.
