With the advancement of electronics, the different technologies used in computer vision, helps to recognize a hand written character more effectively and yields a reliable output. Password protection is a current challenge and it has various methods involved in it. On-line hand writing character recognition using accelerometers is the basic proto-type for all the latest technologies. In this project, the recognition process is done by using a micro-electromechanical device (MEMS) Accelerometer and Microcontroller within built ADC and using I2C interface. The system uses processor to store the characters and it is interfaced to the computer for recognizing the data with any of Integrated Development Interface (IDE) as Visual Basic. There are advance techniques in research of password by studying blood veins of a person’s palm, such as bio-metric techniques works on accelerometers in built.
