Yahoo Password Frequency Corpus

This dataset includes sanitized password frequency lists collected from Yahoo inMay 2011. <br>For details of the original collection experiment, please see:<br>Bonneau, Joseph. "The science of guessing: analyzing an anonymized corpus of 70 million passwords." IEEE Symposium on Security &amp; Privacy, 2012.http://www.jbonneau.com/doc/B12-IEEESP-analyzing_70M_anonymized_passwords.pdf<br>This data has been modified to preserve differential privacy. For details ofthis modification, please see:<br>Jeremiah Blocki, Anupam Datta and Joseph Bonneau. "Differentially Private Password Frequency Lists." Network &amp; Distributed Systems Symposium (NDSS), 2016.http://www.jbonneau.com/doc/BDB16-NDSS-pw_list_differential_privacy.pdf<br>Each of the 51 .txt files represents one subset of all users' passwords observedduring the experiment period. "yahoo-all.txt" includes all users; every otherfile represents a strict subset of that group.<br>Each file is a series of lines of the format:<br>FREQUENCY #OBSERVATIONS...<br>with FREQUENCY in descending order. For example, the file:<br>3 12 11 3<br>would represent a the frequency list (3, 2, 1, 1, 1), that is, one passwordobserved 3 times, one observed twice, and three separate passwords observedonce each.本数据集包含2011年5月从雅虎（Yahoo）采集的脱敏密码频率列表。 如需了解原始采集实验的详细信息，请参阅： Bonneau, Joseph. 《猜测的科学：分析7000万匿名密码的匿名语料库》，IEEE安全与隐私研讨会，2012年。http://www.jbonneau.com/doc/B12-IEEESP-analyzing_70M_anonymized_passwords.pdf 本数据已进行修改以保障差分隐私（differential privacy）。如需了解此次修改的详细信息，请参阅： Jeremiah Blocki, Anupam Datta 与 Joseph Bonneau. 《差分隐私的密码频率列表》，网络与分布式系统研讨会（Network & Distributed Systems Symposium，简称NDSS），2016年。http://www.jbonneau.com/doc/BDB16-NDSS-pw_list_differential_privacy.pdf 本次数据集共包含51个.txt格式文件，每个文件均对应实验周期内观测到的全部用户密码的一个子集。其中`yahoo-all.txt`涵盖所有用户；其余每个文件均为该用户群体的严格子集。 每个文件均采用如下格式的多行文本： 频率（FREQUENCY） 观测次数（#OBSERVATIONS）…… 且频率（FREQUENCY）按降序排列。例如，某文件内容为： 3 12 11 3 该内容对应的频率列表为(3, 2, 1, 1, 1)，即1个密码被观测到3次，1个密码被观测到2次，另有3个独立密码各被观测到1次。
