UNIT 3 – QUESTION 1


We have shared a few examples of how information can be extracted from data (such as in your images). What are other ways humans can leave traces of information with the use of technologies?

There are some ways that humans may leave their information while using technologies, including:

– Application software: when using transportation, e – commerce or food delivery apps, users are required to provide their locations, spending habits or financial status. These types of data may be extracted and taken advantage of by marketers, hackers or cyber criminals. 

– Social media platforms: Social media users often update their personal data such as photos, private messages, phone numbers, locations, birthday, gender, financial and married status on their personal pages. Besides, search history is also a way of risking users’ data. 

– Online gaming: gamers may reveal their personal data when they sign up, in-game chat with unknown people, or send messages. 

– Black websites: internet users may happen to click the black websites or disguising links, which leads to the risk of their data.
