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?
Possibly the most prominent way in a high school student’s life that we leave traces of information is through social media. Just as the photos that we take can be connected with a timestamp and location, every time a person posts on Facebook, Instagram, Snapchat, TikTok, Twitter, YouTube etc., there is a timestamp attached to it. Additionally, while not every post needs to have a location attached to it, many do, which leaves traces of our movements for anyone to see. Additionally, chosen hashtags and language on social media can leave traces of information depending on the language of the post; #canberra, for example, is another way to make it clear that your post is coming from Canberra. Snapchat additionally has a “Snapmap” feature, where you can see exactly where your friend are in the world on a map.
Students must be aware of these factors of social media (and the internet in general) when utilising this; it can be dangerous to leave these traces out there for the public to see. For example, if you post something from the same coffee shop every Friday at 2pm, it would be easy for anyone to track your location with these tags. Another consideration will be that students should be careful with sharing features such as that on the “Snapmaps” on Snapchat; it can be dangerous to share your exact location with a person you do not know.
