High Value Data Sharing Protocol

Overview
In June 2009, the governments of the United Kingdom, Canada, the United States, Australia and New Zealand (the Five Country Conference) signed a joint agreement to pursue biometric data sharing for immigration purposes. Under the agreement, known as the high value data sharing protocol, the countries will share a limited number of immigration fingerprint records (approximately 3,000 per country per year) for matching against the other countries' immigration databases. If a match is found, further biographical information will be shared on a bilateral basis.
