Method for preventing imposter fraud during blood-pressure measurement

Abstract

With the recent rapid growth in personal devices, the amount of data generated by individuals is increasing. When third parties think of using such data for their services, it is important to ensure that the data is authentic. As the first step in achieving this, we previously developed a system to ensure the authenticity of an legitimate person’s blood-pressure data using pulse waves. However, if a user measures his/her blood-pressure with this system, it is necessary to keep touching the authentication device during measurement. To improve the usability of this system, we evaluated the feasibility of a pulsewave extraction method using face sequence images. We conducted a pulsewave-extraction experiment in August 2015. From the results of the experiment, we found that we should use a video camera with a high frame rate and remove the effects of face movement.
