Abstract

The present technology relates to a file processing device and a file processing method for enabling restriction of viewing of an image. A file control unit generates a file that stores an encrypted image obtained by encrypting an image with a first encryption key, and an encrypted encryption key obtained by encrypting the first encryption key with a second encryption key, the encrypted image and the encrypted encryption key being associated with each other in the file. The file control unit also decrypts the encrypted encryption key in the file into the first encryption key, and, with the first encryption key obtained by the decryption, decrypts the encrypted image into the image. The present technology can be applied to a digital camera and the like that capture images, for example.
