Research On Verification Algorithms Of Electrocardiogram

ECG(Electrocardiogram) has been a very useful tool for detection and analysisof the disease by the doctor, when it was found. But in the beginning of the21thcentury, it is found by some researchers that the ECG signal can be used as abiological characteristic for human verification. Based on the deep survey of theresearches and development of the ECG verification at home and abroad, this papersummarizes and provides three effective verification algorithms of the ECG, andevaluates deeply each algorithm with two experiments designed carefully. The firstexperiment aims at providing a fair environment for the testing of the the threealgorithms based on the same training data. The second experiment designed forexamining the verification function of these algorithms in the real practicalcondition. Though using the ECG as a verification tool is available, it is just in thestarting of the theory research, for conquer the problem of the real ECG verification,a lot of hard works needed to be done. This paper also provides a useful and easyhardware architecture and sofeware procedure. The main achievements of this paperare listed below:(1) Based on the real application of the ECG verification, designing a practicaluseful hardware architecture and sofeware process, combining with the wirelessfunction, providing more convenience. It has useful referred value for the realapplication of the ECG verification.(2) Providing three practicable algorithms, and using the experiment and datato test their verification effect. Each of these three algorithms catch the eigenvaluesfrom the ECG wave by different direction, and gets a better verification success rate.The results clearly denote that it is available for the ECG verification of the real lifecondition, and can help the others design and realize a useful ECG verificationalgorithm in the future.(3) Solving the questions that do the ECG identification, under the long timeand sport statuses, and get better result.By the comparison of these three algorithms, the mean-cycle algorithm is thebest one, coming from the modification of the template matching, also explain t hatthe template matching is a very strong and useful tool in the field of the ECGverification. Of course, the Advanced RBP algorithm based on the mathematicstatistics also obtains a good verification result, moreover this kind of algorithmhave a strong anti-interference ability. Inexact AC algorithm has the similarverification result with the Advanced RBP algorithm, its status tree make the patternupdate better and the matching more quickly. After the deep research on these three algorithm, it is clear that how to analysethe ECG wave, to realize the human verification better. Based on the advantages anddisadvantages of these three algorithm and the solution of the long time and sport,the more practicable and more stable verification system of the ECG can bedesigned out.
