In a closely-watched case, the U.S. District Court for the Western District of Washington recently held that Internet Protocol (“IP”) addresses do not constitute personally identifiable information (“PII”). The plaintiffs in Johnson v. Microsoft Corp. brought a class action suit against Microsoft claiming that the collection of consumer IP addresses during the Windows XP installation process violated the XP End User License Agreement. The Agreement stated that Microsoft would not collect PII without the user’s consent. The plaintiffs referenced Microsoft’s own online glossary to support their claim that IP addresses should be considered PII. The glossary defined “personally identifiable information” as “[a]ny information relating to an identified or identifiable individual. Such information may include…IP address.” In granting summary judgment in favor of Microsoft, U.S. District Court Judge Richard Jones found that “[i]n order for ‘personally identifiable information’ to be personally identifiable, it must identify a person. But an IP address identifies a computer.”

A recent federal court decision offers a detailed analysis of several theories of liability for violations of a privacy policy.  Pinero v. Jackson Hewitt Tax Service Inc., No. 08-3535, 2009 WL 43098 (E.D. La. January 7, 2009). 

Plaintiff Pinero visited Jackson Hewitt Tax Service in Louisiana to have her tax returns prepared.  During her visit, she provided Jackson Hewitt with confidential information such as her Social Security number, date of birth and driver’s license number.  Pinero signed Jackson Hewitt’s privacy policy, which stated that Jackson Hewitt had policies and procedures in place, including physical, electronic, and procedural safeguards, to protect customers' private information.  Pinero alleged that she relied on this statement in her decision to turn over her information.
