In this world, that it would be a school, office, banks or apartment the only thing which we concern is safety and security. In this case, we are trying to keep our personal belongings safe like data, money and other important files to be secured from unauthorized persons. To overcome this technology, we are going to represent a fingerprint and algorithm-based security system that provides complete security and making unable to access for unauthorized person or someone else. Therefore, in this system, we are going to tighten the security for the unauthorized person. In this system, we are going to authorize the person's fingerprint who is going to open the locker or door. This fingerprint recognition is only done by the Arduino Uno to check for authentication. In this case, if the person has the correct fingerprint matched with the registered fingerprint, the door willautomatically open otherwise the GSM module will be triggered and the registered person will get the concern alert message and the buzzer connected will be intimate the sound to alert the surroundings officially. Here we have done a few algorithms for more safety purposes.

Human Detection in the Images of a Single Camera for a Corridor Navigation Robot

In this paper, a robot vision technique is presented to detect obstacles, particularly approaching humans, in the images acquired by a mobile robot that autonomously navigates in a narrow building corridor. A single low-cost color camera is attached to the robot, and a trapezoidal area is set as a region of interest (ROI) in front of the robot in the camera image. The lower parts of a human such as feet and legs are first detected in the ROI from their appearances in real time as the distance between the robot and the human becomes smaller. Then, the human detection is confirmed by detecting his/her face within a small search region specified above the part detected in the trapezoidal ROI. To increase the credibility of detection, a final decision about human detection is made when a face is detected in two consecutive image frames. We tested the proposed method using images of various people in corridor scenes, and could get promising results. This method can be used for a vision-guided mobile robot to make a detour for avoiding collision with a human during its indoor navigation.
