Globally, countless numbers of people are missing every day including children, adolescents, the mentally challenged, adults with Alzheimer’s, and so on. Most of them have not been tracked. This paper proposes a program that can help police and the public by speeding up the search process using face recognition. If a person is missing, people related to that person or the police can upload a photo of that person which will be stored in a database. If the public meets a suspicious person, you can photograph and upload a photo of that person on our site. The face recognition model in our system will try to find the same on the website with the help of face code text. It is done by comparing the face text of the uploaded image with the face text of the image on the website. If a match is found, you will be notified by the police and the people related to that person and the place where that person is found. The facial recognition model we have used maintains 99.38% accuracy on the Face Unveiled Wild Benchmark covering 13,000 images. The most troubling fact about the missing Indian children is that although on average 174 children go missing every day, half of them are not traced. A report by the National Crime Records Bureau (NCRB) quoted by the Department of Home Affairs (MHA) in Parliament (LS Q no. 3928, 20–03–2018), more than one lakh children (1,11,569 in real numbers) were reported missing until 2016 , of which 55,625 remained unavailable until the end of the year. Statistics, however, are an indication of the lack of a national repository for Missing Children. "There are no funds set aside to trace the missing persons," said an official source.
