A SYSTEM FOR USER IDENTIFICATION AND CONTACTLESS TEMPERATURE DETECTION AND A METHOD THEREOF FIELDOFINVENTION
The present invention generally relates to a field of image processing and data storing systems. More specifically, the present invention relates to the field of user identification and contactless temperature detection.
BACKGROUND OF THE INVENTION
Body temperature is determined by the temperature of blood, which emits heat as far-infrared radiation. The temperature of a body is usually measured by placing a thermometer inside the tongue or under armpits for a definite interval of time for detecting the temperature.
In the current scenario where disease is spreading through contact, measuring the temperature manually by touching each and every individual can be a good mode of spreading diseases.
There exists a need to develop a system that measures the temperature of the person from a certain distance without contacting the person.
In a current situation, person being sick and having a temperature in body are not following social distancing and are coming in contact with other healthy person and spreading the diseases. It is almost impossible to manually track each and every sick person from spreading the disease to a healthy person.
Moreover, entering inside the organizations and other institutions require a user to authenticate the identity so that unauthenticated users are not allowed to enter. Most organizations and institutions use biometric system for authenticating the user to enter and restrict other from entering in order to maintain the security.
Due to the pandemic, authenticating the user through manually placing the finger on the biometric module. This contact with the biometric module requires the user to place the finger on the biometric module and authenticate the user.
In order to overcome the above-mentioned limitation, there exists a need to develop a system that is able to register the user and continuously track the real time activities of the registered user.
Therefore, there exists a need to develop a system that authenticates the user without contact.
The technical advancements disclosed by the present invention overcomes the limitations and disadvantages of existing and convention systems and methods.
