Privacy

"privacy" is extended so widely today and exposed a lot of concern, especially by the internet.

i admit there are somethings people don't want others to know, say, your bankbook passwords, your email passwords, or  a set of personal data that is qualified to be used on the things that make you lose, say, people can use your citizenship number and address and phone number and birthday to pretend your relatie and get money from your bank. or use this identity to commit crime that you never did.

notices that the many "and" between those items, only your address make no harm. coz people can always make up this address, but it is the COMBINATION that define you, or the social identity that is you in the court or in bank. therefore, your phone number, your citizenship number, your address, your blood type, your medical history, your finger print ALONE. is not important and should nto be counted as secret at all. coz the data alone fail to represent a person and function as "another" identity. ( fake identity is, picke one some data that the combination is not a real person in the world, say, Barack Obama, born in 12, July, 1964, blood type B, etc.. is not the a real person! so, that is fake identity )

however, people are easy to be scared by things they don't understand. and or some private reasons, they don't like those data are able to be known by others.
