Abstract: This paper proposes the design and development of security system for visitor validation at entrance using Raspberry Pi and Elliptical curve digital signature with WiFi network connectivity. When visitor presses the doorbell switch at entrance it is captured by the GPIO pin of Raspberry Pi. Once Raspberry Pi gets the signal it activates the Raspi camera to capture the image in jpg format. The image gets time stamped. The data in the jpg format is than authenticated using ECDSA (Elliptical Curve Digital Signature Algorithm) process that takes current time as seed to generate private key and required signatures. The authenticated image along with its signature are zipped and sent to the authorized e-mail address. Upon receiving the e-mail notification the image file can be verified by the user in both Windows and Linux operating system that has verification program installed in it to know whether signature matches with the image. The advantage of the system is that the user can verify image from anywhere and anytime and can respond to the situations. The setup uses Raspberry Pi 3, Raspberry Pi Camera and MIRACL software library, along with tactile switch and bread board.
