Abstract: According to an embodiment, an electronic device comprises: a communication circuit, at least one processor, and memory storing instructions. The electronic device may convert a first image into a latent vector using an encoder. The electronic device may obtain a first hash value by applying a hashing method to the latent vector for the first image. The electronic device may compare the first hash value for the first image with a second hash value for a second image; and determine whether the first image is plagiarized based on a result of the comparison.

Abstract: A base station of a communication system may include an antenna; a memory; and a processor. The processor analyzes a signal received through the antenna to determine if the received signal is a signal transmitted from a fake base station. Based on a determination that the source of the received signal is the fake base station, the processor generates a random access preamble signal for accessing the fake base station. The processor transmits the generated random access preamble signal through the antenna. Thus, the base station may effectively defend against an attack from a fake base station by detecting the fake base station based on collected information of a neighboring base station and causing radio resources of the detected fake base station to be exhausted. Various other embodiments are possible.
