Abstract
An electronic device in an example embodiment may include a communication interface configured to receive an original file, a memory, and a processor. The processor may generate bit information corresponding to uppercase and lowercase letters included in a filename of the original file. The processor may generate a case insensitive (CI) filename in which the filename of the original file is expressed by characters of a first type. The processor may encrypt the CI filename and may calculate a first hash value corresponding to the encrypted CI filename. The processor may record filename metadata including at least one of the encrypted CI filename, a length of the encrypted CI filename, the first hash value, and the bit information, in the memory. The processor may search for a target file to be found based on the filename metadata.
