In democratic political systems based on the secrecy of vote, substantial levels of privacy, integrity and authentication have been and are indispensable requirements to sustain the internal communications of formal and informal democratic citizens’ organizations, as well as "social networks".A substantial level privacy and reliability of communications among 2 or more citizens has been and is indispensable to ensure the effectiveness of citizen's constitutional rights to communicate. Today, most human communications in the developed world happen through 2-way telematic services involving hardware and software on both ends.
Current laws allow and encourage producers to market and distribute computers, electronic devices and telematic services that, in turn, allow the potential illegal abuse of privacy of their users in a mass scale by several ICT companies, governmental agencies, criminal groups, or just as well by sub-groups or individuals within such entities.
But such risks have been around since the times of postage and telephone... What has changed radically during the last few years is the hugely decreased cost per person/per minute of such communications privacy abuses, together with the greatly reduced ability of police and judiciary to ascertain such mass privacy legal breaches.
For the first time in history, hugely lowered costs and risks make it economically feasible for a large number and type of entities to continuously monitor and analyze illegally millions of people, with extremely low risk of getting caught per each abuse.
On the contrary, since very secure operating systems and encrypted communication software and protocols are widely available through the world, criminal individuals and groups (including entities illegally mass abusing citizens privacy!), can communicate via email and VoIP with a very low possibility of even (legal) military or NSA agencies to decrypt or detect such communications about illegal activities.
