In general, oral or written publication, in any manner, of material that violates a person’s right of privacy would be considered as a personal injury.
However, your credit card slip may show a few digits of the credit card you use for the transaction and such would NOT be considered as a personal injury, because the word “publication” would not apply to this example.
Other examples of personal injury: libel and slander, publishing / disclosing personal related information (health records, financial, etc) to a public domain without prior approval, false arrest and trespassing.
Always consult with your insurance policy for a proper understanding on what is covered and not under your personal injury.
