Keystroke timing information for 2,522,186 characters typed over several months

Keystroke dynamics for one user for 2.5M characters typed over several months. Consists of one text file, each line being a typed character, and a Unix time stamp. For privacy reasons the characters typed are randomly mapped to another character, same mapping across the whole dataset, so timing information for bigrams and trigrams can be extracted but not mapped to actual typed characters.<br>

本数据集为单用户历时数月累计录入250万个字符的击键动力学（Keystroke Dynamics）数据集。该数据集仅包含一个文本文件，文件中每一行均对应一个击键字符与一条Unix时间戳（Unix Time Stamp）。出于隐私保护需求，原始输入字符将通过全局统一的随机映射规则替换为其他字符，因此尽管可提取双字组（bigram）、三字组（trigram）的时序信息，但无法将其还原为实际输入的原始字符。
