Understanding Personally Identifiable Information (PII): How the U.S. Is Rethinking Data Privacy



Today, as we exist in an age of hyperconnectivity, data is money—most notably, Personally Identifiable Information (PII), which is the most valuable data of all. Each time we make an online purchase, log into an app, or register for a service, we provide pieces of information that, when combined, provide a very rich profile of who we are. Regulatory compliance and secure handling of such information is now one of the largest legal and ethical challenges of the 21st century.

What Is PII and Why It Matters

PII is any information associated with a particular individual, either directly (a full name, Social Security number, or passport information) or indirectly (ZIP code, IP address, or date of birth). In other words, direct identifiers are clear representations of someone, while indirect identifiers can be a lot of things but become identifiable by association.

PII, if compromised, can cause real harm. Cybercriminals can use it to engage in identity theft, financial crime, or phishing. Exposed PII not only harms individuals but can harm corporate reputations and lead to a decline in public trust.

The Global Push for Data Privacy

Across the world, governments are enacting stronger data protection laws. The European Union’s General Data Protection Regulation (GDPR) remains the gold standard, setting out stringent requirements for consent, data minimization, and breach notification. Other regions, such as Canada (with PIPEDA) and Australia (under the Privacy Act), have followed suit with similar protections.

The United States, however, takes a different approach. There is no single, overarching federal data protection law. Instead, privacy regulation is fragmented across multiple state and sectoral laws — such as the California Consumer Privacy Act (CCPA), the Health Insurance Portability and Accountability Act (HIPAA) for healthcare data, and the Gramm-Leach-Bliley Act (GLBA) for financial institutions.

This patchwork framework means the level of protection varies depending on where you live and which companies you interact with. In practice, businesses must navigate a complex maze of state-level regulations and industry standards, while consumers must stay vigilant about how their data is collected and shared.

The Growing Frequency of Data Breaches

Despite new legislation and heightened awareness, data breaches continue to occur with alarming regularity. Organizations across sectors — from finance to healthcare — face constant threats from ransomware, phishing, and insider negligence.

One recent example highlighting the risks of PII exposure is the Cohen Fashion Optical data breach, reported in late October 2025. Attackers allegedly accessed hundreds of gigabytes of sensitive customer information, including personal and medical data. While investigations continue, incidents like this underscore how easily consumer data can become a target, even for well-established companies.

The Challenges of Protecting PII in the U.S.

The U.S. faces a unique challenge in balancing innovation with privacy. The country leads in technological development, yet its legal framework often struggles to keep pace with evolving digital threats. Several challenges persist:

  1. Fragmented Regulation: Different states enforce varying standards, creating inconsistency in how companies must respond to breaches.
  2. Corporate Accountability: Many firms still treat cybersecurity as a compliance issue rather than a core business risk.
  3. Low Public Awareness: Consumers often share personal information without understanding the long-term consequences.
  4. Rise of Emerging Technologies: Artificial intelligence and the Internet of Things (IoT) are generating massive amounts of identifiable data, often without explicit consent.

Moving Toward a Culture of Privacy

Protecting PII requires more than regulatory compliance — it demands a cultural shift. Companies must embed privacy-by-design principles into every product, system, and workflow. This means encrypting sensitive data, minimizing unnecessary collection, and regularly testing systems for vulnerabilities.

Consumers, too, have a role to play. Using strong, unique passwords, enabling multi-factor authentication, and staying alert to phishing scams can significantly reduce personal risk. Regularly reviewing breach notices and acting quickly — by changing passwords or monitoring credit — is essential.

The Future of PII Protection

The debate over data privacy in the U.S. is evolving rapidly. Several proposals for a federal privacy law are under discussion, aiming to unify the fragmented system and bring the country closer to global standards. Until then, both organizations and individuals must operate with the assumption that breaches can and will happen.

The protection of personally identifiable information is not just a technological concern — it’s a social contract. Every stakeholder, from lawmakers to consumers, shares responsibility for safeguarding data in an era defined by digital dependence.

Conclusion

Personally identifiable information is the basis of the modern identity, and its protection defines the integrity of the digital universe. As data flows across countries and industries, trust can only be maintained with transparency, accountability, and security that is forward-looking. The implications of global laws like GDPR and breaches like Cohen Fashion Optical demonstrate one thing: protecting personal data is not optional. It is simply the cost of doing business in the digital age.

Visage Imaging Data Breach Shows Growing Threat to Radiology Data Security

Image
The Visage Imaging data breach proves the troubling truth about today's health care system, in that medical imaging companies are one of the most sought-after targets for cybercriminals. Medical imaging companies deal with very sensitive information from patients, many of which are stored in databases that utilize many layers of third-party applications. When combined with the outdated technology of most medical imaging systems, it makes them vulnerable much quicker than the majority of medical facilities can secure them. Imaging companies do not receive the attention for cybersecurity that hospitals typically receive, but they are part of a larger, more distributed network that supports the operations of radiologists, clinics and third-parties. Imaging companies are responsible for coordinating the thousands of diagnostic images and reports they send throughout this network and then back out to the respective users. Medical imaging organizations have been around for many years an...

Pelican State Credit Union has revealed that a recent security breach involving a third-party vendor has resulted in the exposure of sensitive user information. The incident is at the forefront of ongoing discussions around the challenges faced by financial institutions regarding the security of sensitive information aligned with their operations and data handling through external vendors. After Pelican State Credit Union discovered the  Data Breach incident on August 15, 2025, it was reported that Marquis Software Solutions—a vendor providing software services to Pelican State Credit Union—had experienced a compromise of their data security system. An investigation into the incident determined that an unidentified individual may have gained access to or acquired computer files containing private user data. Marquis Software subsequently alerted Pelican State Credit Union in late October of 2025 regarding the likelihood that user's personal information had been compromised, prompti...
