Data protection during remote monitoring of person’s state

Abstract

Problem of human personal data protection in telemedicine systems is considered. The model of possible threats is developed for a mobile measuring system that provides continuous monitoring of a person’s state by recorded biosignals. The problem of ensuring the confidentiality and integrity of personal data transferred from the sensor to the cloud is identified. Possible ways of protection of the transmitted information in systems for remote monitoring of person’s state are systematized. An original method of personal data protection is presented. It is shown that the necessary information for construction of cryptographic keys can be obtained by appropriate processing of biosignals. It is proposed to use biosignals registered by sensors to construct symmetric cryptographic keys, which reflect the physiological characteristics of the patient and can be used to conceal information. The processing of biosignals is based on the reconstruction of a mathematical model that generates time series, which are diagnostically equivalent to the original biosignals. Examples of reconstruction by biosignals for obtaining physiological signature of the person are given.
