Filmmakers want cameras with encrypted storage

All data can be securely erased, but it takes time so most systems will, by default, simply remove the file pointers. This means the space becomes available for re-allocation to some other set of files, but until it actually is re-allocated (and overwritten) the original content is still sitting out there can can be recovered easily.

Plus it’s kind of worse on SD, Flash, etc, because the wear leveling is almost built to leave your data recoverable unless you use a utility which takes the feature into account or you fill up all the free space on your drive after you remove the sensitive files.
