Abstract: A method, an apparatus, and a system for solving and managing security problems, which may occur during a handover of a User Equipment (UE) between PLMNs in a mobile communication network, by using a Non-Access Stratum (NAS) protocol are provided. By the method, a UE can perform a security mode command and an authentication with a network. Further, the method can prevent interruption of communication due to authentication or security during a handover of a UE between Public Land Mobile Networks (PLMNs).

Abstract: The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure provides a method and a device for enhancing data security. The method includes when a request message including information related to a first privacy level is received from a user device, authenticating the user device. The method also includes verifying the information related to the first privacy level. The method further includes transmitting, to the terminal, an image processed on the basis of the first privacy level among images processed on the basis of a plurality of privacy levels.
