What is Personally Identifiable Information?
Personally Identifiable Information, or PII, refers to data that can be used on its own or in conjunction with other information to identify, contact, or locate a single person. This includes direct identifiers like social security numbers and email addresses, which can uniquely identify a person.
Additionally, it encompasses quasi-identifiers such as a person’s date of birth, race, or gender, which, when combined, can be used to accurately identify an individual. Understanding PII is crucial for data protection and privacy, as misuse of this information can lead to identity theft and other privacy violations.
PII in the context of technology and big data
The digital era has significantly transformed how PII is collected and used. With the advent of technologies like smartphones and social media, there’s been a dramatic increase in the volume of data generated. This proliferation of digital data, often termed ‘big data,’ is extensively analyzed and processed by businesses, providing deep insights into consumer behavior and preferences.
However, this surge in data collection brings with it heightened risks of data breaches and cyberattacks. As more personal information becomes digitally accessible, it becomes a target for malicious entities recognizing its value. This trend has sparked widespread concern over how businesses and organizations handle sensitive consumer data, prompting regulatory bodies to advocate for stronger data protection laws. In response, there’s a growing trend toward seeking more secure, anonymous digital interactions, underscoring the critical need for robust PII management and protection strategies in our increasingly connected world.
Sensitive vs. non-sensitive personally identifiable information
Sensitive PII: This category includes data that is not available in the public domain and is, essentially, private. Examples include full names, Social Security Numbers, driver’s licenses, mailing addresses, credit card information, passport details, financial and medical records. Sensitive PII demands heightened security, such as encryption, both in transit and at rest, due to legal and ethical requirements for privacy.
Non-Sensitive PII: This refers to information that is generally available in public domains like phonebooks or online directories. It includes zip codes, race, gender, dates and places of birth, and religious affiliations. While individually these may not identify a person, when linked with other data, they can reveal someone’s identity. Non-sensitive PII becomes critical when combined with other identifiers, necessitating careful handling to prevent unintended linkage and identification.
Examples of PII
Personally Identifiable Information (PII) is categorized into two distinct groups: direct and indirect identifiers. Direct identifiers are specific to an individual, encompassing items such as passport and driver’s license numbers, which alone can pinpoint a person’s identity.
On the other hand, indirect identifiers encompass broader, less distinctive data, like an individual’s racial background or birthplace. Although these elements on their own may not reveal an individual’s identity, in combination they have the potential to do so.
In-depth breakdown of Personally Identifiable Information (PII)
Direct identifiers:
- Personal identifiers: Full name, home address, email address.
- Government IDs: Social security number, passport number, driver’s license number.
- Financial data: Credit card numbers, bank account details.
- Contact information: Personal telephone numbers, email addresses.
- Property details: Vehicle identification number (VIN), property titles.
- Digital identifiers: Processor or device serial numbers, Media Access Control (MAC), Internet Protocol (IP) addresses, device IDs, cookies.
- Login credentials: Usernames, passwords.
Indirect identifiers:
- Common names (either first or last).
- General location data: Country, state, city, zip code.
- Demographic information: Gender, race, age range (e.g., 30-40).
- Employment details: Job position, workplace.
- Personal characteristics: Photographs, fingerprints, handwriting samples.
- Biometric data: Retinal scans, voice signatures, facial geometry.
A notable example of a data breach involved Facebook (now Meta) and Cambridge Analytica. In the 2010s, Cambridge Analytica, through a University of Cambridge researcher, developed a personality quiz app on Facebook. This app harvested data not only from the quiz participants but also, due to a Facebook system loophole, from the participants’ connections. In total, over 50 million users’ data was harvested without consent. Despite Facebook prohibiting such data use, Cambridge Analytica sold this information for political consulting purposes.
This incident had significant financial repercussions for Facebook, incurring $3 billion in legal expenses as reported in early 2019, impacting its financials considerably. The breach led to a tarnished reputation for the social media giant, substantial fines, and a decline in user trust and engagement.
The importance of securing PII
Securing Personally Identifiable Information (PII) is essential to protect individuals from various risks, most notably identity theft and privacy breaches. When PII such as social security numbers, email addresses, or financial details fall into the wrong hands, it can lead to serious consequences.
Identity thieves can use this information to impersonate individuals, access their financial accounts, or even commit fraud in their victims’ names. Additionally, unauthorized access to PII can lead to privacy violations, where sensitive personal details might be exposed without consent. This not only leads to potential financial losses but also to a loss of trust and damage to personal reputation.
In the digital age, where information can spread rapidly, the impact of such breaches can be far-reaching and long-lasting. Thus, safeguarding PII is not just a personal responsibility but also a crucial aspect of maintaining online security and trust in the digital ecosystem.
How is PII used in identity theft?
The misuse of Personally Identifiable Information (PII) plays a central role in identity theft, a serious concern in our digital society. Identity thieves often target PII such as names, social security numbers, driver’s license numbers, and bank account details to perpetrate their crimes.
With access to this sensitive information, criminals can fraudulently assume someone’s identity, applying for loans, making purchases, or even committing crimes in the victim’s name. They may also gain unauthorized access to personal accounts, from banking to social media, causing financial loss and reputational damage.
The theft of PII for such purposes not only impacts individuals financially but also compromises their personal and professional lives. This underlines the critical need for stringent measures to protect PII and prevent its exploitation in identity theft.

Who is responsible for protecting PII?
The responsibility for protecting Personally Identifiable Information (PII) in the United States primarily falls under the Privacy Act of 1974. This Act governs how federal agencies handle PII, emphasizing respect for individual privacy during the collection, use, and dissemination of personal data. It also demands transparency from these agencies and grants individuals rights to access and amend their personal records.
While this Act directly applies to federal agencies, it significantly influences data privacy practices in other sectors, setting a standard for handling personal information.
Beyond the federal realm, the absence of a comprehensive federal data privacy law means that private sector entities often operate under state-level regulations, such as California’s Consumer Privacy Act. This creates a diverse regulatory landscape, with each state having distinct compliance requirements.
In addition to government agencies and private companies, individuals themselves play a crucial role in protecting their PII. They need to be aware and cautious about sharing personal information, practicing safe online behaviors, and staying updated about potential security threats.
GDPR and PII in the European Union
In the European Union, the General Data Protection Regulation (GDPR) represents a significant legal framework in the protection of PII. The GDPR places stringent requirements on organizations collecting and processing the personal data of EU residents, regardless of the organization’s location. It emphasizes the principles of consent, right to access, and the right to be forgotten, providing individuals greater control over their personal data.
Under GDPR, organizations are required to implement adequate data protection measures, report data breaches within a specific timeframe, and ensure the privacy and security of processing PII. This regulation has set a high standard for data privacy globally, influencing policies and practices beyond European borders.
Overall, the task of protecting PII involves a collaborative effort between government bodies, private sector organizations, and individual citizens, each contributing to a safer digital environment.
