If you don't know the inside details of how exactly the NSA conducts its phone surveillance programs, it's worth a read, as it goes into a lot of detail on just how and what it collects and what privacy safeguards are now in place. And, somewhat unsurprisingly, the agency says that it's meeting all of the privacy measures that are now required of it.
The report details how the agency faired across a total of eight different categories referred to as "fair information practice principles." Those principles include transparency, individual participation, purpose specification, data minimization, use limitation, data quality and integrity, security, and accountability and auditing. According to the report, the NSA "satisfies" six of those eight principles, which two others are a little less clear.
Unsurprisingly, the two outlying categories are transparency and individual participation. The transparency principle calls for organizations to notify individuals regarding collection and usage of their personally identifiable information (PII), while the individual participation principle calls for organizations to involve the individuals and seek consent with possible for the collection and use of PII. In the former case, the CLPO found that "the robust public debate of the USA Freedom Act, as well as the Government's release of detailed information about NSA's implementation of the statute" was enough to "adequately address" the transparency principle.
As for the individual participation principle, the idea of giving someone a head's up that you're tracking their phone calls is a pretty massive tip-off, so the NSA hasn't really been doing it. The NSA writes in its report:
"If a target of an international terrorism investigation becomes aware of the investigation, he or she likely will take steps to thwart investigators. The targets of such investigations also attempt to conceal from the government the identities of their contacts. As a consequence, direct individual participation thwarts the legitimate need to identify individuals engaged in international terrorism."
Due to this conflict, the CLPO concluded that the NSA's behavior regarding this principle was "appropriate under the circumstances."
