What is Sensitive Personal Information (SPI)? 

4 min to read

Sensitive Personal Information (also known as SPI), refers to personal information that is sensitive by nature and can usually identify a specific individual. SPI is varied, but it can include aspects such as:

• Race and ethnicity

• Religious and political views

• Trade union membership status

• Biometric data

SPI can also include whether a user has a criminal record, their sexual orientation, genetic information, and various other data elements. Considering the potential for privacy breaches associated with SPI, additional safeguards are crucial for mitigating risks. The CCPA, GDPR, and other data protection laws have stringent guidelines that you should follow.

Pro Tip:
Prioritize the best SPI practices if you want to increase user privacy. Strong encryption, only collecting necessary data, and handling exposure-related risks are all important.
Key Takeaways:
  • Sensitive Personal Information (SPI) requires additional protection compared to general PII
  • SPI includes information like race, genetic data, and medical information
  • Following common SPI protection practices and adhering to legal obligations is essential

What makes certain data or categories ‘sensitive’? 

Generally speaking, you’ll know if data is sensitive if the risks associated with it being exposed are higher. While sensitive personal information may be linked to fraud, identity theft, and other cyber security threats, the absence of such links does not guarantee security. 

Data that is categorized as sensitive typically involves personal information that pertains to private aspects of a person’s life, such as their health information, financial records, or family relationships. This frequently involves keeping individuals’ private or sensitive information confidential unless essential. 

Because of the risks associated with sensitive personal information being leaked, it’s vital that you implement the strongest security measures. Doing so should limit the chances of unauthorized exposure, though it does not guarantee this. 

Pro Tip:
Use strong passwords and consider implementing multi-factor authentication. 

How does SPI differ from PII? 

The main difference between SPI and PII (personally identifiable information) is that SPI is significantly more sensitive and valuable. This is especially true for cyberattackers. However, SPI is a subset of PII – and knowing both of them is important. 

SPI contains information that, when misused, can result in discrimination and other harmful activities, highlighting the importance of responsible usage. This is the main reason that this kind of information requires additional protection by law, such as encryption. PII doesn’t need such strong measures most of the time, but you should still protect user information to a strong enough level. 

Pro Tip: 
Treat all PII as sensitive. Implement access control, encryption, and other measures – even if the information is not technically SPI.

While it’s important to consider the legal importance of handling SPI appropriately, you should also think about the business aspects. How you handle SPI can impact your business reputation and how much customers trust you.Understand all of the legal necessities for jurisdictions in which you operate and ensure that you’re compliant with them.

What constitutes SPI mishandling is subject to local laws, so it’s crucial to comply with the specific regulations in each relevant region. If you don’t, the ramifications are often significant. You may face criminal prosecution, for example, and whether you’re a business or individual, you could be liable to fines and penalties. 

Pro Tip: 
Research SPI legal requirements in every jurisdiction you serve. If needed, hire a legal advisor with comprehensive knowledge of the rules in each region. 

How is biometric data classified (SPI or PII)? 

Biometric is classified as both SPI and PII. This is mainly because SPI is a subset of PII. Although categorized as SPI due to potential harms associated with unauthorized access, the safeguarding of biometric data necessitates strict protocols and careful handling. 

You can use biometric information to identify specific individuals, and for this reason, protecting it is of the utmost importance. You should implement several measures that will ensure data protection, such as a zero-trust policy and strong credentials that only the necessary people know.

The GDPR, CCPA, and similar regulations will define SPI and protect it accordingly. When complying with these laws, you should only process data like biometrics if it’s an absolute necessity. You should also give users control over their most sensitive information. 

Although SPI protection is complex, taking the time to understand regulations and definitions should help you avoid mishaps.

Conclusion

Given the possibility of substantial harm if mishandled, SPI necessitates more extensive and robust protection protocols compared to those required for PII. Regulations can sometimes be complex, and they will vary depending on where you operate – but understanding all of them is very important. 

One of the best ways to protect against breaches is to treat all PII – even if it’s not “sensitive” by definition – with the utmost importance. Though data protocols may not guarantee complete protection, they can assist in threat detection and customer data security efforts.
