Unit 3


  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? Share an example or examples with the community.

The way people leave traces of information with the use of technologies is through digital footprint. Whenever we go online, we are leaving our digital footprints. Digital footprint is referred to the information that remains on the internet as a result of our activity online. Examples of digital footprint includes our browser search history, photos we are tagged in, comments we leave online, as well as our deleted text messages.

If we are not careful, these digital footprints that we leave online can be seen by other people and can even be traced on in a database by big businesses to track our spending behaviour and even trace our personal information such as credit card number. Hence, we should always be mindful of the digital footprints we leave behind and always keep our personal information private by switching on privacy settings as much as possible.
