PPG Dataset

The UDESC PPG biometric dataset was created to address specific research requirements regarding Continuous Authentication via Photoplethysmogram signals. A minimum of two samples per subject taken days apart was ensured. Every sample incorporates a series of PPG signals. The age of subjects was incorporated as it significantly affects the fingertip PPG signal. Additionally, subjects' resting conditions were controlled and consistent, creating a more reliable dataset. The final dataset comprised of 30 subjects each contributing two separate samples, collected in a controlled environment.UDESC PPG生物特征数据集旨在满足基于光电容积描记图（Photoplethysmogram）信号开展连续身份认证的特定研究需求。该数据集确保每名受试者至少采集两份样本，且两次采样间隔不少于数日。每份样本均包含一系列PPG信号。研究人员纳入了受试者的年龄信息，因为年龄对指尖PPG信号具有显著影响。此外，所有受试者均处于受控且一致的静息状态，以此提升数据集的可靠性。最终构建的数据集共包含30名受试者，每人提供两份独立样本，所有样本均在受控环境下采集完成。
