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>

本数据集为单用户在数月内键入250万个字符时采集的键盘动力学数据。数据集包含单个文本文件，每行对应一个键入字符及对应的Unix时间戳。出于隐私保护考量，所有键入字符均通过全局统一的随机映射规则替换为其他字符，因此可提取双字符组（bigram）与三字符组（trigram）的时序信息，但无法将其还原为实际键入的原始字符。
