ECG SECURITY SYSYTEM

Abstract

Now-a-days security and privacy is an essential field in the Technology world. We are working on a security system based on ECG signals. A number of different kind of ECG machines are available in the market and it is also highlighted in the research that single channel ECG can be acquired by making a closed loop with a circuit placed on human wrist. In this project, we have designed a prototype of an embedded device which will be placed as a wrist band and will acquire a single channel ECG. The main principle of the project is that we gather the ECG signals of certain authorized people and add it into the database. Now based on this database we cross check any ECG who tries to access the system. The security system then allows only valid/matched authorized ECGs to access. The project methodology is based on several portions which includes Integration of Sensors where We have Integrated the sensors to get the required data from the concerned person (in the form of ECG) and then we have transferred that data to Arduino on which we have applied pre-processing to get a smooth and workable signal form and then after extracting their features we have cross checked it against the database. Then the system confirms that whether this sample can/cannot access the system. Our main aim is to have a system which can ensure security based on ECG signals. It should be noted here that the project though has a title which manifests its inclination to security systems but due to the concept of intelligent ECG sensing nature it can be applied to various daily life activities. Daily life banking, car locking, hence wherever a biometric is used ECG can replace it ensuring enhanced security
