Biometrics are body measurement and calculation which is related to human characteristics. Biometric authentication is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance.
Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. A biometric identifier is also categorized as a physiological characteristic that is related to the shape of the body for example such as fingerprint, palm veins, face recognition, DNA, Palm print, hand geometry, iris recognition, retina, and odor/scent. Thus behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythm, gait, keystroke, signature, behavioral profiling, and voice.
Biometric monitoring devices are sensors embedded in a smartphone, wearable technologies examples such as wrist bands, skin patches, or everyday objects such as smart cap bottles that offer the opportunity to collect biological, physiological, or behavioral patient data, continuously, remotely, and unobtrusively
ECG (Electrocardiogram) devices
An electrocardiogram is a device that records the electrical signals in your heart. Its common and painless test is used to quickly detect heart problems and monitor your heart’s health. Electrocardiograms also called ECGs or EKGs are often done in a doctor’s office, a clinic, or a hospital room ECG rooms and ambulances. Some other personal devices such as smartwatches, offer ECG monitoring
EMG (Electromyography)
Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. ECG is performed using an instrument called an electromyography to produce a record called an electromyogram. Thus it detects the electric potential generated by muscles cells as these cells are electrically neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order, or recruitment order, or to analyze the biomechanics of human or animal movement
