Free Software extensions for cameras such as Magic Lantern http://www.magiclantern.fm/ http://www.magiclantern.fm/ exist. I wonder if it's possible to add encryption support there, before images are written to the SD card?
- Joeboy 10y agoMaybe, but I think the cameras are already working at full tilt just to encode the file. Also I don't think you can run ML on anything professional, and Canon's consumer range are increasingly poor value for video.
- dom0 10y agoThey'd have to add at least an AES engine to the chips, but that's really not a big factor in terms of transistors or power usage. (Although, if they're using some ARM cores somewhere, they probably already have one or two of these lying around).
- Joeboy 10y agoWe're talking about Magic Lantern, which is a third party firmware hack that's not supported by Canon, so they can't do anything to the hardware. I suppose it is possible the processor accidentally supports some encryption primitive(s).
- Joeboy 10y agoWith hindsight this was a slightly stupid thought as you could just encrypt the file after writing it. Although that could mean it stayed unencrypted if somebody seized the camera while you were still recording.
- zimpenfish 10y agoThe article references http://www.magiclantern.fm/forum/index.php?topic=10279.msg99214#msg99214 http://www.magiclantern.fm/forum/index.php?topic=10279.msg99... which is old, experimental, somewhat faffy, and a bit buggy.
- Joeboy 10y agoAlso looks (at first glance) like it's only for stills (".CR2 and .JPG").
