So, what is meant by your digital footprint, well whenever you use the internet you’re leaving a series of digital footprints. These footprints are the lasting impression of all the activities you perform online. Your digital footprints can be seen by others, particularly if you are using social networks like Facebook and Twitter.
Sometimes these footprints can be hidden, such as your order history on Amazon, your PayPal purchases, or your searched terms on browsers like Google or Bing. Although most users on the internet cannot see these particular footprints, they are still lasting impressions about you stored online. Therefore, you need to ask yourself if you trust every website and service that you use to keep your data secure and use it appropriately.
Though it is impossible to have no footprint if you use the internet, there are ways to reduce your footprint. This video explains what your digital footprint is and how to reduce it.
All the information that you share online contributes to your digital identity. Your identity is made of what you share online, however, it may include things you didn’t consciously share. For this reason, you need to carefully manage your online activities and curate your online identity.
Many individuals form multiple identities online. Sometimes this is to keep personal, business, and/or study in separate digital spheres to stop personal issues from blending into professional spaces. Others construct online identities as pseudonyms to isolate their true selves from their online activity. This can be to protect personal information about themselves, to hide something they think is embarrassing, or to cover up criminal activity.
Having multiple identities online in most cases (with the exception of criminal activity) is completely fine and often the services people use online encourage this. This doesn’t mean making yourself a completely different person online is okay for example Facebook encourages people to connect with friends and family whereas LinkedIn encourages people to act professionally and connect with colleagues and business professionals. This leads people to act differently on each service, creating unique identities for each service. This kind of isolation is useful as it ensures what you share is appropriate to the audience. However, just as you may be creating your own digital identities, you need to be aware that other users are also doing the same.
