Unit 3 – Question 1

When access to any social network sites (gmail, facebook, instagram, Zalo…), we have to give some personal information, such as phone number, email, pictures even ID number. So, we leave behind a trail of information known as your digital footprint. A digital footprint grows in many ways – for example, posting on social media, subscribing to a newsletter, leaving an online review, or shopping online.

Sometimes, it’s not always obvious that you are contributing to your digital footprint. For example, websites can track your activity by installing cookies on your device, and apps can collate your data without you knowing it. Once you allow an organization to access your information, they could sell or share your data with third parties. Worse still, your personal information could be compromised as part of a data breach.
