Digital footprints

12 Sep 2018

Your digital footprint is everything in the digital world that is about you.

Every day, whether or not you want to, you are leaving behind a trail of data that puts together a picture of who you are online, what you are doing, where you are going, and why you are doing all these things. This picture is likely more public than you assume. It lets companies better tailor content to your likes and dislikes; it helps universities check your backgrounds before accepting you; it allows advertisers to track your proclivities for purchases; and it allows your potential dates to find out a lot about you before even meeting.

These consequences of leaving digital footprints may not trouble you, if you think ‘you have nothing to hide’. However, everyone has something to hide – be it our personal affairs or our credit card numbers – and digital footprints make it easier to uncover these private details. Criminals often use information that reveal parts of someone’s personal life to steal from someone, blackmail them, or even steal their identity! Although it is not possible to have zero digital footprints, it is possible for you to reduce the number of digital breadcrumbs you leave while traversing online spaces. 

What are examples of digital footprints?

  • Your search history
  • Text messages, including deleted messages
  • Photos and videos, including deleted ones
  • Tagged photos, even those you never wanted online
  • Likes/loves on sites like Facebook and Instagram
  • Browsing history, even when you are on ‘Incognito’ mode

Why does my digital footprint matter?

  • Once information is online, it can be difficult (or impossible) to remove
  • People’s digital footprint determines their digital reputation, which is now as important as their offline reputation
  • Words and photos can be easily misinterpreted and altered, causing unintentional insult
  • Content intended for a private group can easily spread to a broader circle, hurting relationships and friendships
  • Most employers check their potential employees’ digital footprints, particularly their social media, before hiring them, and universities check their prospective students’ digital footprints before accepting them too

What can I do to leave better digital footprints?

  • Stop and ask yourself these questions before you post, forward, or reply to something: what would someone who doesn’t know me think of me if they saw this? Would I want someone else to post this about me? If this was on a billboard for everyone (my parents, friends, teachers) to see, would I be okay with it? If the answer to any of these questions is no, maybe you should not post it
  • Remember to treat others like you want to be treated
  • Set your settings on social media sites to ‘Private’, and check and update this regularly
  • Turn off geo-tagging or location settings on your phone and social media
  • Check the content you are being tagged in, and remove those that are offensive or inappropriate
  • If you have posted content you regret, remove it immediately
  • If you find that you are posting lots of things that are hurtful to yourself or others, it might be good to take a break from social media for a while
