Amends the Communications Act of 1934 to expand responsibilities of telecommunications carriers with respect to the confidentiality of subscriber (customer) calling records, both cellular and land-line based. Allows a carrier to use individual calling records only for purposes such as increasing business or publishing directories, and prohibits a carrier from otherwise disclosing CPNI without express prior authorization by the subscriber. Directs the Federal Communications Commission (FCC) to prescribe regulations adopting more stringent security standards for CPNI (including detailed customer telephone records) to detect and prevent confidentiality violations. Provides penalties for such violations.
