Analysis of the prospects for using fitness bracelets as a source of biometric information when synthesizing the biosignature of an important document

Abstract

The possibility of increasing the effectiveness of the use of the so-called biosignature due to the transfer in its composition of an expanded set of bioparameters characterizing the functional and psycho-emotional state of the author of the document at the time of its signing or approval is shown. Analysis of the entire set of bioparameters transmitted as part of the biosignature, as well as their comparison with similar individual parameters characteristic of the author’s normal working and calm state, makes it possible to identify cases of his inappropriate behavior, including obtaining a signature under duress or under the influence of narcotic substances. Along with such bioparameters as heart rate, blood pressure, and pupillary response, the study examines the possibility of recording hand tremor. This informative indicator allows you to assess the level of nervous tension of the author of the document, and also makes it possible to identify a number of diseases of the author, which may also be a reason for declaring the document incompetent. The study examines the possibility of using a fitness bracelet to record hand tremor. Experimental studies have shown that hand tremor recorded by accelerometers and a gyroscope, usually included in the fitness bracelet, can be measured with good accuracy by these gadgets, taking into account the level of their own noise. The advantage of the considered approach is also that the fitness bracelet, as a rule, is constantly on the hand, which makes it possible to register the bioparameters of the author at the time of working with the document. The use of cell phones, smartphones and other wearable devices for this purpose is not always possible, since at the time of signing or approving the document, the author most likely does not hold them in his hand and places them on the table.
