Privacy is the right to be let alone. 
Everyone wants some privacy, but no one can explain that in a way that matches anyone else's desire for privacy. Privacy is associated with liberty, but also with privilege (private roads, private schools), with confidentiality (private conversations) with nonconformity, with dissent, with shame, with embarrassment, with the deviant, with the taboo, with subterfuge and concealment.
In his dissent to a 1952 Supreme Court decision Justice Douglas issued this stirring defense of the right to be let alone:
"If liberty is to flourish, government should never be allowed to force people to listen to any radio program. The right of privacy should include the right to pick and choose from competing entertainments, competing propaganda, competing political philosophies. If people are let alone in those choices, the right of privacy will pay dividends in character and integrity. The strength of our system is in the dignity, the resourcefulness, and the independence of our people. Our confidence is in their ability as individuals to make the wisest choice. That system cannot flourish if regimentation takes hold. The right of privacy, today violated, is a powerful deterrent to any one who would control men's minds."
The above statement seems to state that the people's character and integrity will be enhanced by the right to pick their own sources of information. There is ample reason to doubt that statement in light of the environment in 2018 where populist demagogues are again persuading people to vote against their own interests by manipulating news sources that appeal to the peoples' prurient interests.  But the statement does seem to clarify that privacy is about liberty, the right to do what you want with yourself and your belongings.
User and Web Site Acceptance for Privacy Seals
Back in 2000 the FTC had the following to say. There is no evidence to-date that things have changed for the better.
The 2000 Survey also examined the extent to which industry's primary self-regulatory enforcement initiatives online privacy seal programs have been adopted. These programs, which require companies to implement certain fair information practices and monitor their compliance, promise an efficient way to implement privacy protection. However, the 2000 Survey revealed that although the number of sites enrolled in these programs has increased over the past year, the seal programs have yet to establish a significant presence on the Web. The Survey found that less than one-tenth, or approximately 8%, of sites in the Random Sample, and 45% of sites in the Most Popular Group, display a privacy seal.
- Users or Consumers have always been a real asset to any business and access that provides user attention (aka eyeballs) to a message is now a commodity to be bought and sold on the internet.
- Technology, and social media in particular, record nearly every transaction that we make, and can retrieve it for any purpose not explicitly disallowed by regulation. The amount of information that Facebook has accumulated about people is far more that most people understand. The constantly evolving problem is to keep the laws protecting citizens from depredations by large organization up-to-date in the face of rapidly accelerating change.
The number of governments that have proposed "Solutions" to the invasions of "The Right to Privacy" is large, but the results are meager and most law enforcement agencies are often in court trying to use any loop-hole to strip away privacy even where products have been specifically designed to maintain privacy. The same laws that protect privacy also protect criminal behavior. Not that privacy laws always make sense; federal law prohibits the National Tracing Center from using a searchable data base to identify the owners of guns seized at crime scenes. No privacy advocate has recommended that law be repealed.
Privacy Enhancing Technology Providers have been proposed and are actively explored by Microsoft and IBM. Their uptake has been negligible because of two factors: they are clumsy for users and they don't provide much privacy. The real problem facing users today is how to stop digital agents from using your information once they acquire it. The GDPR is designed to control the movement of users private data from one enterprise to another. The State of California now has a initiative scheduled for ballot that focuses more on places where your data exits. But neither of them addresses the problem of your data in some third world country, or island nation, from misuse. In some ways the GDPR is a scam in that it is more about penalizing corporations in California for the benefit of bureaucrats in Europe than helping with existing loss of privacy.
- Help effort like the new citizen initiative filed with the secretary of state in California to limit the sale of user data.
- Pay attention to security and privacy notifications on your computer
- Never click on a link or call a phone number that you cannot validate as legitimate.
- See the page on GDPR which went into effect on 2018-06-24.
US Federal Regulations
ACM's U.S. Technology Policy Committee (USACM) this week (2018-07-02) submitted recommendations to the Senate Commerce Committee's Subcommittee on Consumer Protection, Product Safety, Insurance, and Data Security that focus on protecting personal privacy in the wake of the Facebook and Cambridge Analytica scandal. USACM urged Congress to immediately act to protect the public good and the integrity of the democratic process by addressing technical and ethical issues raised by the data breach. Specifically, USACM wants Congress to draft and adopt comprehensive personal privacy protection legislation extending beyond social media to meet nine critical goals, including limiting collection/minimizing retention of personal data; clarifying and simplifying user consent processes and maximizing user control of data, and simplifying data-sharing policies and assuring data-flow transparency. USACM chair Stuart Shapiro says the organization has significant expertise in the technical and ethical aspects of the case, and looks forward to serving as an apolitical resource for Congress in pursuit of solutions.
