In this paper, we design an intelligent backpack based on wireless mobile technology, which includes a backpack ontology, mobile terminal, and terminal app. On the backpack ontology, there are several related modules such as the master control chip, voice recognition module, wireless transmission module, GPS/GPRS module, and acceleration gyroscope module, among others. To enhance security and privacy, we have integrated a fully anonymous authentication scheme based on hash functions and elliptic curves. This scheme ensures the confidentiality, security, and user’s privacy. The master control chip communicates with the terminal app through the wireless transmission module. The backpack can realize wireless network services, multimedia services, security functions, and more. The experiment results show that the intelligent backpack can ensure personal and property safety when the backpack user faces danger. Therefore, the intelligent backpack has strong emergency response capabilities, real-time features, and it has a promising application prospect.
