On April 13th, it's become an essential part of our daily lives, but do you worry that your phone might be eavesdropping on your conversations?
Some users have noticed that after discussing a particular product, they see related advertisements on shopping websites.
Experts believe that this is actually due to highly accurate user profiling rather than phones "listening" to your conversations.
Apps gather information such as user searches and browsing history to precisely target advertisements, but this approach carries high costs and legal risks.
Experts explain that achieving phone eavesdropping requires keeping the phone's microphone constantly on, significantly increasing its energy consumption.
Moreover, it entails identifying different scenarios, multiple speech speeds, dialects, etc., which incurs high costs.
In contrast, accessing information through other means such as user search history and browsing records is more reliable and valuable.
Therefore, experts advise users to exercise caution and avoid using apps from unknown sources as much as possible to mitigate the risk of eavesdropping and covert filming.
