From using social media to traveling to airports (i.e. biometric services like Clear and TSA Precheck), modern life essentially requires us to give up data and privacy for our daily activities. These practices apply to our vehicles and in some cases also include our private conversations. Due to the constant risk of hacker attacks and data leakage, many people are looking for ways to not only provide less data, but also to protect themselves from harmful threats.
The most tempting and easily accessible methods of powering off include GPS jammer, and audio or voice protection systems, sometimes called voice jammers. When looking at these different anti-surveillance devices, it is important to recognize the differences between them, especially in terms of legality. GPS jammers are illegal devices. Audio jammers are legally and morally correct, and are named incorrectly because their functions are completely different from highly illegal jammers.
