I dont think that 'invasion of privacy' can be defined exhaustively. Such a definition should evolve over a period of time. Enumerating the kinds of info that may lead to invasion of privacy may also prove to be fallacious since very often it may depend on the context in which the said info is used or called for. Interpolating UK's definition of 'sensitive personal data' to define the concept of 'invasion of privacy' under our
RTI may be undesirable.
