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.

File processing device and file processing method including file that stores encrypted image

The present technology relates to a file generation device, a file generation method, a file reproduction device, a file reproduction method, and a program capable of associating an image stored is a file with external data outside the file. A file control unit generates an association-type high efficiency image file format (HEIF) file in which an image in an HEIF file compliant with HEIF and specific information that specifies external data outside the HEIF file, the external data to be associated with the image, are stored in association with each other. Furthermore, the file control unit reproduces the association-type HEIF file. The present technology can be applied to a case where an HEIF file is generated or a case where the HEIF file is reproduced.
