NIST Special Database 301 Nail to Nail (N2N) Fingerprint Challenge Dry Run

In April 2017, the Intelligence Advanced Research Projects Activity (IARPA) held a dry run for the data collection portion of its Nail to Nail (N2N) Fingerprint Challenge. This data collection event was designed to ensure that the real data collection event held in September 2017 would be successful. To this end, biometric data from unhabituated individuals needed to be collected. That data is now released by NIST as Special Database 301.

2017年4月，美国情报高级研究计划局（Intelligence Advanced Research Projects Activity，IARPA）为其“指甲到指甲（Nail to Nail，N2N）指纹挑战赛”的数据采集环节举办了预演测试。本次预演活动的核心目标是保障2017年9月开展的正式数据采集环节顺利完成。为此，需从未经采集流程适应的个体处采集生物特征数据。该批数据目前已由美国国家标准与技术研究院（National Institute of Standards and Technology，NIST）以特种数据库301（Special Database 301）的形式正式对外发布。
