The above definition is slightly wrong.
Doxing or Doxxing is the act of identifying a person from one small bit of information such as an email address. The "Doxer" uses this email address to find out phone numbers, address, real name etc of the target. Doxing is "legal" as long as you are only finding publicy available information, it becomes illegal if you stalk the person through online chat services, like facebook or msn, or if you hack into their social accounts, like facebook, twitter, gmail hotmail etc.
