Abstract
In the constant advancement of technology, protection of one's property becomes a major concern for each individual. To secure one's property the protection such as locks and keys mechanism were used but this mechanism can be easily replicated. This study aims to developed a device and a security system that replaced the conventional lock and keys mechanism to secure one's property. This device also established a strong security based on the secret knock pattern security system. This security system consists of Arduino Mega, Piezo Sensor, and uses a Secret Knock that is known only to the owner. The researchers conducted hardware and system functionality. Thirty (30) trials were made in checking the accuracy of changing knock patterns where they obtained a 100% accuracy. Thirty-one (31) trials were made to check the accuracy of detecting incorrect patter. The experiments conducted obtained a 100% accuracy in detecting incorrect pattern.
