Which of the following pieces of information would be classified as personal data?
Select three correct answers

• Social security number
• Driver license number
• Date and place of birth
• Job title
• IP address

The correct answers are:

• Social Security Number (SSN)
• Driver’s License Number
• Date and Place of Birth

These pieces of information are classified as personal data because they can be used to identify an individual uniquely or in combination with other data, making them sensitive and subject to data protection laws.

Understanding the Classification of Personal Data

In the realm of data protection and privacy, personal data refers to any information that relates to an identified or identifiable individual. With the increasing digitization of information, understanding what constitutes personal data is critical for both individuals and organizations. Among the many types of information that can be considered personal data, three key examples are the Social Security Number (SSN), the driver’s license number, and the date and place of birth. Each of these data points holds significant implications for privacy and security, making them subject to strict legal protections.

Social Security Number (SSN)

The Social Security Number (SSN) is one of the most sensitive pieces of personal data, particularly in the United States. It serves as a unique identifier issued to U.S. citizens, permanent residents, and certain temporary residents. Originally created to track individuals’ earnings and determine their Social Security benefits, the SSN has since evolved into a de facto national identifier used in various contexts, including employment, taxation, and financial transactions.

Why the SSN is Classified as Personal Data:

1. Unique Identification: The SSN is a unique number assigned to each individual, making it one of the most direct identifiers available. Unlike other forms of identification that might be shared or duplicated (like a name), an SSN is exclusive to one person. This exclusivity means that anyone who has access to an individual’s SSN can potentially access a wide range of personal information linked to that number.
2. Broad Use and Dependence: The SSN is used across various sectors, including government agencies, financial institutions, and healthcare providers. This widespread use means that the SSN is deeply embedded in systems that manage sensitive personal data. Consequently, if an SSN is compromised, it can lead to significant breaches of privacy and security.
3. Risk of Identity Theft: One of the gravest risks associated with the SSN is its potential for use in identity theft. If a malicious actor gains access to someone’s SSN, they can potentially open credit accounts, access tax records, or even apply for government benefits in the victim’s name. This makes the protection of SSNs a critical concern for both individuals and organizations.
4. Legal Protections: Recognizing the sensitivity of the SSN, various laws have been enacted to protect it. For example, the U.S. Privacy Act of 1974 restricts the use of SSNs by government agencies, and the Fair Credit Reporting Act (FCRA) places limits on how financial institutions can use SSNs. Additionally, under the General Data Protection Regulation (GDPR) in Europe, any identification number that uniquely identifies an individual is considered personal data, and its handling is subject to strict regulations.

Driver’s License Number

The driver’s license number is another critical piece of personal data. Like the SSN, the driver’s license number is a unique identifier issued by government authorities, typically state or provincial departments of motor vehicles. This number is tied to an individual’s driving record and is often used in various legal and administrative contexts.

Why the Driver’s License Number is Classified as Personal Data:

1. Government-Issued Unique Identifier: Similar to the SSN, the driver’s license number is a unique identifier that is assigned to an individual. It is used by government agencies, law enforcement, and various private sector entities to verify identity, making it a valuable piece of personal data.
2. Association with Other Personal Information: The driver’s license number is linked to a variety of other personal information, including the individual’s full name, date of birth, address, and physical characteristics. This linkage makes the driver’s license number a gateway to a wealth of personal data, which, if compromised, can lead to serious privacy violations.
3. Usage in Verification and Authentication: Many organizations use the driver’s license number as a key piece of information for verifying identity. For instance, financial institutions may require a driver’s license number when opening accounts, and employers might use it to conduct background checks. This reliance on the driver’s license number for verification purposes further underscores its importance as personal data.
4. Potential for Fraud: Just like the SSN, the driver’s license number is a target for identity thieves. If someone gains unauthorized access to an individual’s driver’s license number, they can use it to commit various forms of fraud, such as obtaining loans or opening accounts in the victim’s name. This makes it crucial to protect the driver’s license number from unauthorized access.
5. Regulatory Safeguards: In recognition of the sensitivity of driver’s license numbers, laws such as the Driver’s Privacy Protection Act (DPPA) in the United States impose strict controls on how this data can be accessed and used. The DPPA limits the disclosure of personal information from motor vehicle records, ensuring that driver’s license numbers are protected from misuse.

Date and Place of Birth

The date and place of birth are often considered less sensitive than the SSN or driver’s license number. However, these pieces of information still qualify as personal data because they can be used, especially in combination with other data, to identify an individual or verify their identity.

Why the Date and Place of Birth are Classified as Personal Data:

1. Role in Identity Verification: The date and place of birth are commonly used as security questions or in other identity verification processes. For instance, financial institutions or government agencies might ask for this information to confirm someone’s identity when they attempt to access services or retrieve lost passwords. This usage makes the date and place of birth important pieces of personal data.
2. Potential for De-anonymization: In cases where data has been anonymized, the inclusion of birth data can sometimes be used to re-identify individuals, especially if combined with other data points. For example, in a small community, knowing the date and place of birth might be enough to single out an individual. This risk makes the date and place of birth more significant in the context of data protection.
3. Security and Privacy Risks: While the date and place of birth alone might not be sufficient to commit fraud, they can still pose security risks when combined with other information. For example, in cases of social engineering attacks, knowing someone’s date and place of birth might help a malicious actor in convincing an organization or individual that they are someone they are not.
4. Use in Profiling: In some cases, date and place of birth information can be used to create profiles of individuals, particularly in contexts like healthcare or marketing. This profiling can lead to privacy concerns, as individuals might be targeted or categorized based on their age or place of origin.
5. Legal Considerations: Under data protection laws like the GDPR, any data that can be used to identify an individual, directly or indirectly, is considered personal data. This includes the date and place of birth, which, when combined with other data, can contribute to identifying an individual.

Conclusion

In conclusion, the Social Security Number, driver’s license number, and date and place of birth are all classified as personal data due to their potential to uniquely identify an individual or significantly contribute to their identification when combined with other information. These data points are protected by various legal frameworks to prevent misuse, particularly in the context of identity theft, fraud, and privacy violations. As personal data, they require careful handling, secure storage, and strict access controls to ensure that individuals’ privacy and security are maintained. Understanding the classification and importance of these data types is crucial for organizations and individuals alike in today’s data-driven world.
