Protecting Rights of Unknowing Dads and Fostering Access To Help Encourage Responsibility (Proud Father) Act of 2006

Protecting Rights of Unknowing Dads and Fostering Access To Help Encourage Responsibility (Proud Father) Act of 2006 - Amends part B (Child and Family Services) of title IV of the Social Security Act to direct the Secretary of Health and Human Services to: (1) establish and maintain an automated National Putative Father Registry; and (2) only accept authentic requests to search the registry. Prohibits the disclosure of information from the registry if it would contravene a national security interest or if such disclosure would compromise the confidentiality of census data.

States that a certificate of search or registration issued by the Secretary serves as rebuttable evidence of efforts to locate a putative father and provide him with notice concerning paternity issues. Requires each putative father to be given notice of: (1) a proceeding concerning a child he has or may have fathered being adopted or entered into state custody; (2) the termination of paternal rights; and (3) the establishment of paternity.

Directs the Secretary to establish a nationwide responsible fatherhood and putative father registry educational campaign.

Requires the Secretary to make grants to states for assistance in programs concerning: (1) improving the protection of the rights of responsible unwed fathers in legal proceedings; (2) improving the laws involving the abandonment of a child by the biological father; (3) assisting mothers in making plans for their children's future; and (4) protecting the privacy and safety of birth parents. Sets forth state eligibility requirements for the grant program, including providing assurances that the state will put into effect a law that defines what constitutes prebirth abandonment and abandonment subsequent to birth.

Provides that any person who knowingly submits false information to a state registry shall be guilty of a misdemeanor and, upon conviction, be subject to a fine. Requires the state to establish procedures to ensure that the information maintained in the registry is subject to established privacy safeguards.
