their site visitors. When a user decided to use P3P, they set their own set of policies and state what personal information they will allow to be seen by the sites that they visit. Then when a user visited a site, P3P will compare what personal information the user is willing to release, and what information the server wants to get – if the two do not match, P3P would inform the user and ask if he/she is willing to proceed to the site, and risk giving up more personal information. As an example, a user may store in the browser preferences that information about their browsing habits should not be collected. If the policy of a
Website stated that a cookie is used for this purpose, the browser would automatically reject the cookie. The main content of a privacy policy is the following:
519:(EPIC) has been critical of P3P and believes P3P makes it too difficult for users to protect their privacy. In 2002 it assessed P3P and referred to the technology as a "Pretty Poor Policy". According to EPIC, some P3P software is too complex and difficult for the average person to understand, and many Internet users are unfamiliar with how to use the default P3P software on their computers or how to install additional P3P software. Another concern is that websites are not obligated to use P3P, and neither are Internet users. Moreover, the EPIC website claims that P3Ps protocol would become burdensome for the browser and not as beneficial or efficient as it was intended to be.

personal information for others’ benefit. Some believe that there should be a limit to the collection and use of the consumer’s personal data online. Currently, sites are not required under any United States laws to comply with the privacy policies they publish, therefore P3P causes some controversy with consumers who are concerned about the release of their personal information and are only able to rely on P3P’s protocol to protect their privacy.

can compare to privacy preferences of users. The EPIC website says, "The incredible complexity of P3P, combined with the way that popular browsers are likely to implement the protocol would seem to preclude it as a privacy-protective technology," EPIC continues on to state, "Rather, P3P may actually strengthen the monopoly position over personal information that U.S. data marketers now enjoy."
628:(FCRA) of 1970 makes it legal for consumer reporting agencies to disclose personal information only under three specified circumstances: credit, employment or insurance evaluation; government grant or license; or a “legitimate business need” that involves the consumer. A list of other sectoral privacy laws in the United States can be viewed at the Consumer Privacy Guide's website.
481:. It is a publicly available "P3P-enabled search engine." A user can enter a search term along with their stated privacy preferences, and is then presented with a list of search results which are ordered based on whether the sites comply with their preferences. This works by crawling the web and maintaining a P3P cache for every site that ever appears in a search query. The

Internet Explorer extends only to cookie blocking, and will not alert the user to an entire web site that violates active privacy preferences. Microsoft considers the feature deprecated in its browsers and totally removed P3P support on Windows 10.

provides individuals with a certain set of principles about how personal information is collected and the person's rights to protecting their personal data. The act allows individuals to control the type of information that is being collected from them. Various principles are included within the act,

EPIC also talks about how the development and implementation of P3P can cause a monopoly of private information. Since it tends to be only major companies who implement P3P on their websites, only these major companies are tending to then gather this information seeing as only their privacy policies
522:
A key problem that occurs with the use of P3P is that there is a lack of enforcement. Thus, promises made to users of P3P can go unfulfilled. Though by using P3P a company/website makes a promise of privacy and of the use of gathered data to the site’s users, there are no real legal ramifications if

The failure for its immediate adoption can be related to the idea of it being a notice and choice approach that does not comply with the Fair
Information Practices. According to the Chairman of the FTC, privacy laws are key in today’s society in order to protect the consumer from providing too much

The agreement to use P3P not only puts in place unenforceable promises, but it also prolongs the adoption of federal laws that would actually inhibit the access and ability to use private information. If the government were to step in and attempt to protect
Internet users with federal laws on what

Moreover, since there has been an increase of browsers there are more users at risk running into privacy problems. But the
Internet Education Foundation points out that, “P3P has been developed to help steer the force of technology a step further toward automatic communication of data management
292:
P3P is a machine-readable language that helps to express a website’s data management practices. P3P manages information through privacy policies. When a website used P3P, they set up a set of policies that allows them to state their intended uses of personal information that may be gathered from

Additionally, the P3P Toolbox developed by the
Internet Education Foundation recommends that anyone who is concerned about increasing their users’ trust and privacy should consider implementing P3P. The P3P toolbox site explains how companies have taken individuals data in order to promote new

data. This is advantageous over simply reading the original natural language privacy policy on a web site because many privacy policies are written in legalese and are extremely convoluted. Additionally, in this case the user does not have to visit the web site to read its privacy policy.

such as the rule that individual has the right to retrieve the data collected about them at any time under certain conditions. Moreover, the individual's personal information cannot be kept longer than necessary, and not be used for purposes other than those agreed upon to begin with.

Currently, the United States has no federal law protecting the privacy of personal information shared online. However, there are some sectoral laws at the federal and state level that offer some protection for certain types of information collected about individuals. For example, the

At the moment, we aren't sure whether P3P is the best solution. P3P is among the specifications we are considering for support in the future. There have been some issues with how well P3P will protect privacy, and for that reason we have decided to wait until these are resolved.

to keep their personal information secure. P3P was designed to give users a more precise control of the kind of information that they allow to release. According to the W3C, the main goal of P3P "is to increase user trust and confidence in the Web through technical empowerment".

only 15% of the top 5,000 websites incorporate P3P. Therefore, many sites that do not include the code but do practice high privacy standards will not be accessible to users who use P3P as their only online privacy guide.

The main alternative to P3P may not be these technologies, but instead stronger laws to regulate what kind of information from
Internet users can be collected and retained by websites. For example, in Europe, the
