Researchers at NordVPN have devised a test to check if devices eavesdrop on conversations to send targeted ads.
Smartphones listen to what you’re saying via built-in microphones, which is always on so virtual assistants can hear voice commands.
One member of NordVPN research team investigated whether speaking about countries – selected at random – would increase ads for tour businesses and other hospitality companies in that country.
The legality of listening practice hinges on the user consent. Any app spying without consent is illegal.
Consumers can test phones by discussing a unique topic near their device and observing if related ads appear in the following days or weeks.
The test has four-step unique topic selection, discussion, maintaining normal phone usage and observing and analyzing.
Users should audit app permissions, manage voice assistant data, use a robust VPN, and utilise built-in security.
NordVPN suggests users limit app permissions on their devices, including microphone and location access.
Regularly audit social media settings, and be mindful of the information shared online. Even innocuous details can be used for targeted advertising or more nefarious purposes.
Users can encrypt their online communications and sensitive data by using a VPN service, like NordVPN, when connecting to public Wi-Fi networks to prevent eavesdropping.
