Final answer:
Smartphones and smart home devices are two modern information technology devices that can decrease privacy by tracking user behavior and collecting data within private spaces, thereby posing a threat to personal privacy.
Step-by-step explanation:
Two modern information technology devices that can decrease privacy are smartphones and smart home devices. Smartphones carry a wealth of metadata that can reveal patterns in behavior and location data through GPS tracking, and even when anonymized, this data can potentially be traced back to individuals, compromising privacy. Moreover, smart home devices, such as security cameras and smart speakers, can collect audio and visual information within private spaces, again threatening privacy as this data may be subject to unauthorized access or misuse.
The proliferation of these technologies highlights the tension between the benefits they offer, such as convenience and security, and the potential for invasions of privacy. With the increased digital footprint we create, we also raise our exposure to cyber threats and unauthorized surveillance, whether from other individuals, businesses, or government entities. Maintaining a balance between privacy and the functional advantages of these devices remains a significant challenge.
