Eyes are the most important sensitive organ, if any person feels drowsy his eyes blinks pattern and eye blink count changes. This change in blink count tells us that the person level of alertness has changed. People in high risk areas like border security force personnel, nuclear power plant fuel rod observer, security guard cabins of important buildings (parliament, airport, VIP residence, Army or Police head office, armoury, banks) needs to be alert. In our research we will count blinks in common situation and then we count blinks in working situation. If any difference in these blinks count is observed, then change in awareness is there, hence an alarm is initiated. In this system human-computer interface is there. The blinks in our system are counted by the software we have developed in matlab. When the system found the person in in attentive state it starts the alarm, this alarm buzzes continuously until it is switched off by the person. The system works as human computer interface. Key words: Eyes, Blinks, high risk areas, awareness, human-computer interface, Alarm. 1. INTRODUCTION Lack of awareness of security guards is one of the prime causes of crossing line of control, terrorist attack on important buildings, theft, robbery, smuggling and other security issues. If the attentiveness of all such security agents is ensured then the chance of occurrence of any catastrophe is avoided. All the high risk areas need continuous and keen watching. The people involved in this needs to be very watchful and their watchfulness can be ensured by our eye blink counting mechanism which has an alarming system, if any person in security field is found inattentive then the system easily detects it and alarm is turned on. We have developed such a software that measures the difference in blinks in normal and in drowsy state.  Image sequence of the person is taken manually and then it is taken automatically.  Image sequence taken manually and automatically while working was found approximately same.  In this software images of both the eyes are considered.  The software detects the presence of eyes and then it measures the blinks.  Our software will ensure awareness of people in high risk areas.
