"The multiple human needs and desires that demand privacy
among two or more people in the midst of social life must
inevitably lead to cryptology wherever men thrive
and wherever they write."
David Kahn, The Codebreakers
In the age of the vitreous man, whose data are not only collected by different institutions but kept under disclosure, out of reach, uncontrollable and unmanageable for the individual, privacy obtains new importance, receives a much higher value again.
The irony behind is that those who long for cryptography in order to preserve more privacy actually have to trust the same people who first created the methods to "produce" something like that vitreous man; of course not the same individual but persons of the same area of science. It is the reign of experts.
So far about self-determination.

CIA's mission is to support the President, the National Security Council, and all officials who make and execute U.S. national security policy by: Providing accurate, comprehensive, and timely foreign intelligence on national security topics; Conducting counterintelligence activities, special activities, and other functions related to foreign intelligence and national security, as directed by the President. To accomplish its mission, the CIA engages in research, development, and deployment of high-leverage technology for intelligence purposes. As a separate agency, CIA serves as an independent source of analysis on topics of concern and works closely with the other organizations in the Intelligence Community to ensure that the intelligence consumer--whether Washington policymaker or battlefield commander--receives the adaequate intelligence information.
