Internet privacy involves the right or mandate of personal privacy concerning the storing, repurposing, provision to third-parties, and displaying of information pertaining to oneself via the Internet. Privacy can entail either Personally Identifying Information (PII) or non-PII information such as a site visitor's behavior on a website. PII refers to any information that can be used to identify an individual. For example, age and physical address alone could identify who an individual is without explicitly disclosing their name, as these two factors are unique enough to typically identify a specific person.
Internet privacy forms a subset of computer privacy. A number of experts]weasel words[ within the field of Internet security and privacy believe that privacy doesn't exist; "Privacy is dead – get over it" according to Steve Rambam, private investigator specializing in Internet privacy cases. In fact, it has been suggested that the "appeal of online services is to broadcast personal information on purpose." On the other hand, in his essay The Value of Privacy, security expert Bruce Schneier says, "Privacy protects us from abuses by those in power, even if we're doing nothing wrong at the time of surveillance." Privacy concerns have been articulated from the beginnings of large scale computer sharing.
An electronic document is any electronic media content (other than computer programs or system files) that are intended to be used in either an electronic form or as printed output.
Originally, any computer data were considered as something internal — the final data output was always on paper. However, the development of computer networks has made it so that in most cases it is much more convenient to distribute electronic documents than printed ones. And the improvements in electronic display technologies mean that in most cases it is possible to view documents on screen instead of printing them (thus saving paper and the space required to store the printed copies).
Secure communication is when two entities are communicating and do not want a third party to listen in. For that they need to communicate in a way not susceptible to eavesdropping or interception. Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what was said. Other than spoken face-to-face communication with no possible eavesdropper, it is probably safe to say that no communication is guaranteed secure in this sense, although practical obstacles such as legislation, resources, technical issues (interception and encryption), and the sheer volume of communication serve to limit surveillance.
With many communications taking place over long distance and mediated by technology, and increasing awareness of the importance of interception issues, technology and its compromise are at the heart of this debate. For this reason, this article focusses on communications mediated or intercepted by technology.
An electronic envelope or e-envelope is almost like a postal Envelope in function. Where a paper Envelope privately encloses its contents like a mail message, so an Electronic envelope privately encloses its contents like an e-mail message. Currently, e-mail not enclosed in an electronic envelope is like sending a Postcard in the standard postal mail system. Just like the postcard, where any postal worker handling the mail can read its contents, any server operator and programs from governments can read your E-mail (also "email"). E-mail is more or less an electronic postcard (or E-postcard)in function. ("e-" = electronic as in e-mail (email), e-envelope or e-postcard.)
A missive, composed personal or business letter or a document is placed into a postal envelope, usually sealed, addressed and mailed through the Postal system. The envelope can be intercepted and the interceptor of the mail can open it, read it and understand it providing the interceptor can read the language, understand the terminology or break any encryption of data. Most paper mail does not have this happen to it unless a government has a specific interest in a person's mail. When the letter or envelope arrives the recipient opens the sealed envelope, takes out the contents and must have the understanding and knowledge to read it.
