  9. Security of
  
  information -
  1.  
  
    Any
  
  information furnished to the statistics officer or to any person or agencies
  
  authorised under this Act shall only be used for statistical purposes.
  2.  
  
    No
  
  person other than a person engaged in the work of collection of statistics
  
  under this Act or preparation of statistics resultant to such collection shall
  
  be permitted to see any information schedule or any answer to a question asked,
  
  except for the purposes of a prosecution under this Act.
  3.  
  
    No
  
  information contained in any information schedule and no answer to any question
  
  asked shall, except for the purposes of a prosecution under this Act, be
  
  separately published, or disclosed without suppressing the identification of
  
  informants to any agency.
  4.  
  
    All
  
  statistical information published by any agency shall be arranged in such a
  
  manner so as to prevent any particulars becoming identifiable by any person
  
  (other than the informant by whom those particulars were supplied) as the
  
  particulars relating to the informant who supplied it, even through the process
  
  of elimination, unless-
  5.  
  
    that
  
  informant has consented to their publication in that manner; or
  6.  
  
    their
  
  publication in that manner could not reasonably have been foreseen by the
  
  concerned agency or any employee thereof.
  7.  
  
  
  
    For
  
  the purposes of sub-section (4), the Central Government may make such rules or
  
  make such arrangement, as it may consider necessary.
