Information obtained by any agency under this article shall be available to the public unless the director certifies such information to be confidential. The director may make such certification where any person shows, to the satisfaction of the director, that the information or parts thereof, if made public, would divulge methods, processes or activities entitled to protection as trade secrets. Nothing in this section may be construed as limiting the disclosure of information by the division to any officer, employee or authorized representative of the state or federal government concerned with effecting the purposes of this article.

Any person who knowingly and willfully divulges or discloses any information entitled to protection under this section is guilty of a misdemeanor, and, upon conviction thereof, shall be fined not more than $5,000, or imprisoned in the county jail for not more than six months, or both fined and imprisoned.
