Digital footprints are the data trails that we leave behind when we use the internet. They can affect our online privacy and security by revealing our personal information, preferences, habits, and activities to others. Some of the risks of having a large digital footprint are:
- Identity theft : This is when someone uses your personal information, such as your name, date of birth, social security number, or credit card number, to commit fraud or other crimes. For example, someone could use your identity to open a bank account, apply for a loan, or make purchases in your name.
- Cyberbullying : This is when someone uses the internet to harass, threaten, or humiliate you. For example, someone could post hateful or embarrassing comments, photos, or videos about you on social media platforms or websites.
- Online harassment : This is when someone repeatedly contacts you online with unwanted or abusive messages. For example, someone could send you spam emails, make prank calls, or stalk you online.
- Targeted advertising : This is when advertisers use your online activity and preferences to show you ads that are relevant to you. For example, if you search for a product on Google, you might see ads for similar products on other websites.
There are two types of digital footprints: active and passive. Active digital footprints are the data that we intentionally submit online, such as social media posts, online forms, or website logins. Passive digital footprints are the data that are collected about us without our knowledge, such as information from cookies, online databases, or trackers.
Some examples of active digital footprints are:
- Posting a status update on Facebook: This is an active digital footprint because you are voluntarily sharing your thoughts, feelings, opinions, or activities with your friends or followers. You can control who can see your posts by adjusting your privacy settings.
- Filling out an online survey: This is an active digital footprint because you are willingly providing your personal information, such as your name, email address, age, gender, or interests. You should be careful about what information you share online and read the terms and conditions of the website before submitting the survey.
- Creating an account on a shopping website: This is an active digital footprint because you are deliberately creating a profile that contains your personal information, such as your name, email address, password, shipping address, or payment details. You should use strong passwords and avoid using the same password for different accounts.
Some examples of passive digital footprints are:
- Visiting a website that tracks your IP address: This is a passive digital footprint because you are not aware that the website is collecting your IP address. An IP address is a unique number that identifies your device and location on the internet. Websites can use your IP address to analyze your behavior, preferences, or interests.
- Searching for a product on Google: This is a passive digital footprint because you are not aware that Google is storing your search history. Google can use your search history to show you personalized results and ads based on your previous searches.
- Receiving an email from a newsletter you subscribed to: This is a passive digital footprint because you are not aware that the newsletter is tracking your email activity. The newsletter can use tracking pixels or links to monitor when you open the email, click on the links, or forward the email to others.
Some ways to reduce or erase our digital footprints are:
- Deleting or deactivating old or unused accounts: This is a way to reduce our active digital footprints by removing the data that we no longer need or use. For example, we can delete or deactivate our accounts on social media platforms or websites that we don’t visit anymore.
- Adjusting the privacy and security settings of our online profiles: This is a way to reduce our active digital footprints by limiting the access and visibility of our data. For example, we can change the privacy settings on Facebook to control who can see our posts, photos, or friends list. We can also change the security settings on Google to turn off the web and app activity, location history, or YouTube history.
- Clearing the browser history, cache, and cookies regularly: This is a way to reduce our passive digital footprints by deleting the data that are stored on our browsers. For example, we can clear the browser history to erase the record of the websites we visited, the cache to erase the copies of the web pages we viewed, and the cookies to erase the small files that store our preferences or login information.
- Using a VPN or a private browsing mode: This is a way to reduce our passive digital footprints by hiding or masking our online activity. For example, we can use a VPN (virtual private network) to encrypt our data and change our IP address. We can also use a private browsing mode to prevent our browsers from storing our history, cache, or cookies.
- Avoiding clicking on suspicious links or downloading unknown files: This is a way to reduce our passive digital footprints by preventing malware or spyware from infecting our devices. Malware or spyware are malicious software that can steal or damage our data. For example, we can avoid clicking on links or attachments in spam emails, pop-up ads, or fake websites. We can also avoid downloading files from untrusted sources or websites.
