Design and Implementation of Child Missing Registration and Mutual Aid Mini Program Based on Java

With the rapid development of the internet, information dissemination has become faster, which makes it even more important to expedite the handling of child missing cases across the country. In this paper, a missing child registration and mutual aid mini program based on Java was designed and developed. The mini program can record various information about missing children and publicize their basic information. More importantly, it can share information with local public security systems. In the age of information technology, people can make better use of this mini program to participate in the search for missing children and improve the success rate of search operations, bringing positive impacts to families and society.
