The Privacy Shield is a recent (2016) privacy framework managed by the US Department of Commerce and EU counterparts. Organizations can certify beginning 1 August 2016.
What follows is a snip of the description of this effort from the DoC website:
The EU-U.S. Privacy Shield Framework was designed by the U.S. Department of Commerce and European Commission to provide companies on both sides of the Atlantic with a mechanism to comply with EU data protection requirements when transferring personal data from the European Union to the United States in support of transatlantic commerce. On July 12, the European Commission deemed the Privacy Shield Framework adequate to enable data transfers under EU law (see the adequacy determination).
The Privacy Shield program, which is administered by the International Trade Administration (ITA) within the U.S. Department of Commerce, enables U.S.-based organizations to join the Privacy Shield Framework in order to benefit from the adequacy determination. To join the Privacy Shield Framework, a U.S.-based organization will be required to self-certify to the Department of Commerce (via this website) and publicly commit to comply with the Framework’s requirements. While joining the Privacy Shield Framework is voluntary, once an eligible organization makes the public commitment to comply with the Framework’s requirements, the commitment will become enforceable under U.S. law. All organizations interested in joining the Privacy Shield Framework should review its requirements in their entirety. To assist in that effort, Commerce’s Privacy Shield Team has compiled resources and addressed frequently asked questions below.
