打开你心灵的钥匙：基于ECG信号的生物特征认证

A Key to Your Heart: Biometric Authentication Based on ECG Signals

近年来，人们的兴趣已经转向生物特征认证领域，该领域使用用户的生物特征来证明用户的身份。我们探索了一种新的生物特征的基础上的电活动的人的心脏的心电图（ECG）信号的形式。为了探索ECG作为生物特征的稳定性，我们收集了55名参与者在两次会议上的数据，中间间隔4个月。我们还使用消费级ECG监护仪，比医疗级监护仪更经济实惠，更实用。使用标准的方法来评估我们的分类器，我们得到的出错率为2.4%的数据收集在一个会话和9.7%的数据收集在两个会话。实验结果表明，使用消费级监视器收集的ECG信号可以成功地用于用户认证。

Quality Measures in Biometric Systems

Biometric technology has been increasingly deployed in the past decade, offering greater security and convenience than traditional methods of personal recognition. Although biometric signals' quality heavily affects a biometric system's performance, prior research on evaluating quality is limited. Quality is a critical issue in security, especially in adverse scenarios involving surveillance cameras, forensics, portable devices, or remote access through the Internet. This article analyzes what factors negatively impact biometric quality, how to overcome them, and how to incorporate quality mea…

Audio-Visual Biometric Recognition and Presentation Attack Detection: A Comprehensive Survey

Biometric recognition is a trending technology that uses unique characteristics data to identify or verify/authenticate security applications. Amidst the classically used biometrics, voice and face attributes are the most propitious for prevalent applications in day-to-day life because they are easy to obtain through restrained and user-friendly procedures. The pervasiveness of low-cost audio and face capture sensors in smartphones, laptops, and tablets has made the advantage of voice and face biometrics more exceptional when compared to other biometrics. For many years, acoustic information a…

A Survey of Wearable Devices Pairing Based on Biometric Signals

With the growth of wearable devices, which are usually constrained in computational power and user interface, this pairing has to be autonomous. Considering devices that do not have prior information about each other, a secure communication should be established by generating a shared secret key derived from a common context between the devices. Context-based pairing solutions increase the usability of wearable device pairing by eliminating any human involvement in the pairing process. This is possible by utilizing onboard sensors (with the same sensing modalities) to capture a common physical…
