Abstract：
Sensor data has been used in social security and welfare infrastructures such as insurance and medical care to provide personalized products and services; there is a risk that attackers can alter sensor data to obtain unfair benefits. We consider that one of the attack methods to modify sensor data is to attack the wearer\'s body to modify biometric information. In this study, we propose a noninvasive attack method to modify the sensor value of a photoplethysmogram. The proposed method can disappear pulse wave peaks by pressurizing the upper arm with air pressure to control blood volume. Seven subjects experiencing a rest environment and five subjects experiencing an after-exercise environment wore five different models of smartwatches, and three pressure patterns were performed. It was confirmed in both situations that the displayed heart rate decreased from the true heart rate.
摘要：
传感器数据已被用于社会保障和福利基础设施，如保险和医疗，以提供个性化的产品和服务;存在攻击者可以更改传感器数据以获得不公平利益的风险。我们认为修改传感器数据的攻击方法之一是攻击佩戴者的身体以修改生物特征信息。在这项研究中,我们提出了一种非侵入性攻击方法来修改光电容积图的传感器值。所提出的方法可以通过用气压对上臂加压来控制血容量来消除脉搏波峰值。7名受试者体验休息环境，5名受试者体验运动后环境，穿着5种不同型号的智能手表，并进行了三种压力模式。在两种情况下都确认了显示的心率从真实心率降低。
