📌 1. How Does Microphone Access Work?
When we install an app on our phone or computer, we are often asked to allow it to access various features of our device, such as the microphone, camera, and location. Most apps ask for this permission for specific reasons, such as:
- Communication applications (e.g. WhatsApp, Messenger, Zoom) need the microphone for calls.
- Audio recording and note-taking apps (e.g. Google Keep, Voice Recorder) require access to record audio.
- Voice assistant apps (e.g. Google Assistant, Siri, Alexa) are activated by voice commands.
But the big question is whether these apps are constantly listening even when they are not in use.
(I.e. 2. Do Apps Really Listen Without Our Permission?
There's a widespread theory that apps listen to our conversations even when we're not using them, and then display targeted ads. While there's no hard evidence that major companies engage in such practices, there are some worrying signs:
- Targeted ads: Many users report seeing ads for products they just mentioned in their conversations.
- Application permissions: Some apps request access to the microphone even if they don't need it to function.
- Data leaks: In the past, cases of apps recording audio without the user's knowledge have been revealed.
However, major companies like Google, Apple, and Facebook have categorically denied using the microphone for advertising purposes.
🔍 3. How Can We Protect Ourselves from Illegal Eavesdropping?
While there is no absolute proof that apps record conversations without permission, it is a good idea to take precautionary measures for our safety. Some useful tips are:
✅ Disable Microphone Access
- In the mobile settings, we can control which applications have access to the microphone and disable the permission for those that do not need it.
✅ Using Trusted Applications
- We only download apps from official stores such as the Google Play Store and the Apple App Store, to reduce the risk of installing malware.
✅ Application Permissions Control
- When we install a new app, we carefully check the permissions it requests. If an app seems to be requesting irrelevant permissions, it's best not to use it.
✅ Use of Antivirus and Privacy Tools
- Security programs can detect applications that record data without permission.
✅ Activate "Kill Switch" for Microphone
- On some devices, there is a physical switch option to disable the microphone, which offers additional protection.
🔎 4. What Do Big Tech Companies Say?
Large companies, such as Google, Apple, Facebook and Amazon, have categorically denied that they listen to their users' conversations without permission. However:
- The Facebook has admitted in the past that it used people to listen to and analyze user recordings via Messenger.
- Η Google and Apple have also confirmed that they use humans to analyze recordings from voice assistants (such as Google Assistant and Siri), but claim that this is only done when the user has activated the voice command.
- Η Amazon has been criticized for Alexa's data usage, but maintains that users can delete their recordings whenever they want.
