In our process we analysis the ECG signal to find the coronary diseases. Here we use the different types of algorithm is used to find the diseases. The ECG is taken from the heart it is electro signal from the heart. It is normal to non-diseases. That is analysis based on the different peaks like T peak ST peak and P peak. Those peak is change is help to find the abnormal heart beat. In our proposed we use the DWT for extract the feature from the ECG signal we find weather the signal is normal or abnormal. Here we use the SVM classifier to find the ECG categories. And also we can analysis the weather given signal is the authenticated person or not-authenticated persons. In these we extract the same feature but authentication process we take the feature without peak information because here we analysis the heart beat to find the person authentication. In our proposed we find the diseases with also find the authentication details it help to regular minter person details
