What is Data & Why Do We Need to Protect It

Video Summary

Understanding Data Privacy and Its Real-World Impact

Every day, you share personal data online—from banking credentials to social media posts. But what happens to that data, and how can it be protected? Data privacy refers to the responsible handling of personal information, ensuring it’s only accessed or shared with consent. Data protection builds on this by securing data through encryption, access controls, and backups to prevent loss or theft. In the event of a breach, the consequences are severe—identity theft, financial fraud, and loss of trust.

Several high-profile breaches—such as Marriott (2018), Facebook (2018), and Equifax (2017)—have exposed millions of users’ sensitive data, leading to identity theft, lawsuits, and corporate fines. For example, Equifax’s breach leaked 147 million social security numbers, while Target’s 2013 breach cost $18.5 million in settlements. Such incidents underscore why companies must secure data, as breaches not only harm individuals but also damage reputations and businesses.

Real-World Application

Imagine if your banking details were exposed fraudsters could drain your account, damage your credit, and put your financial future at risk. Companies failing to protect data face massive fines, lawsuits, and customer distrust, as in the case of T-Mobile in 2021, where 50 million customers had their data compromised. Strong data protection measures, such as encryption and regular security audits, are essential for both organizations and individuals.

Revisiting Data Protection & Privacy – Introduction to Protected Health Information (PHI)

Protected Health Information (PHI) covers sensitive medical data, including patient names, addresses, Social Security numbers, treatment records, and insurance details. This confidential information requires strict protection due to the risks of identity theft, patient privacy violations, and legal repercussions if mishandled.

PHI must be secured during both transmission and storage—encrypted when transferred, restricted by access controls, and safely stored in encrypted databases. Healthcare organizations are legally required to follow laws like HIPAA, ensuring confidentiality, proper data destruction, and compliance to avoid legal penalties.

Real-World Application

PHI breaches have real-life consequences. For instance, the Anthem data breach in 2015 exposed over 78.8 million patient records, costing the company $115 million in settlements. Unauthorized access to patient information can lead to severe financial and reputational damage. By implementing best practices like encryption and access controls, healthcare providers ensure that patient trust is maintained and sensitive information is protected. Properly securing PHI not only upholds patient rights but shields organizations from lawsuits and heavy fines.
