Personal Identity Information (PII)

What is PII?

Personal Identity Information (PII), also known as P4 data, is a specific category of particularly sensitive data defined as:

Unencrypted electronic information that includes an individual’s first name or initial, and last name, in combination with any one or more of the following:

  • Social Security number (SSN).
  • Drivers license number or State-issued Identification Card number.
  • Financial account number, credit card number*, or debit card number in combination with any required security code, access code, or password such as expiration date or mother’s maiden name that could permit access to an individual’s financial account.
  • Medical information (any information regarding an individual’s medical history, mental or physical condition, or medical treatment or diagnosis by a health care professional)
  • Health insurance information (an individual’s health insurance policy number or subscriber identification number, any unique identifier used by a health insurer to identify the individual, or any information in an individual’s application and claims history, including any appeals records)

PII is sometimes called "notice-triggering data" because State of California Information Practices Act of 1977 (Civil Code Section 1798 et seq.) requires that Personal Identity Information (PII) is appropriately protected and that affected individuals must be notified of any reasonable suspicion of a compromise of that protection. The University is responsible for complying with these legal requirements and for providing employees with information about requirements and responsibilities relating to PII.

*Credit card information is also regulated by the Payment Card Industry (PCI) Data Security Standard.

Data Management Practices for PII

In general, the best way to protect PII is not to have it in the first place.

If you handle PII make sure you know how to best protect it.

Common places where PII may be found

University-related PII is likely to be found in files and email containing the following types of information. While this is not an all-inclusive list, you can use it as a guide to locate PII you may not be aware of so you can remove or protect it. Remember to check old and archival files and email, too.

  • Student records, including old class lists, student rosters, financial aid and grade records
    • One way to locate older class lists is to search your older email for messages from Any that are older than September 1, 2004 are likely to be class lists with Social Security numbers.
  • Personnel- or academic-related spreadsheets, databases, and files
  • Old Lx/Rx forms, UPAY forms, Travel Reimbursements and Pro Card Forms
  • Health, medical, or insurance records
  • Downloads from Banner/FIS, PPS, AIS, DivData, or Data Warehouse/InfoView
  • Financial spreadsheets
  • Old applications (job or student), performance evaluations or letters of reference
  • Credit card sale records
  • Credit and collections records
  • Research proposals or databases, research grant applications, or other Intellectual Property (IP)
  • Data related to DMV pull notices

Examples of electronic devices on which PII may be stored include:

  • Desktop and laptop computers
  • Servers
  • Personal or home computers used for University business
  • Portable electronic devices, such as phones, tablets, and other mobile devices
