I gather that the main goal of a dash camera is to capture evidence of an incident so that you can use it to your own benefit. However, some may be worried that their camera might work against them. It's not hard to imagine a scenario where video recorded by your camera is confiscated and used against you, so for people who want to guard against that, I suggest that a solution could be a camera that incorporates Public Key Cryptography.
Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic protocols based on algorithms that require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked.
PGP is a popular cryptographic package that has been under continuous development for about 24 years and includes public-key cryptography, using an open standard. There are other such programs available as well, and many of them are free. A camera could be programmed with an optional feature where a public key could be stored in its memory and used to encrypt video before it's written to memory. The only way the video could be played back would be to decrypt it with the private key that was generated on your computer along with the public key. (The private key is normally stored in an encrypted, password-protected format.)
For marketing purposes this feature would probably be configured as an option that could be ignored by users who found it to be too complicated, but would be available for people who wanted to use it. The only drawbacks I can think of are that the camera would require more capable computer hardware, and, of course, the camera would not be able to play back video that it had recorded.
The more I think about it the more it seems like an obvious idea, which means that it might already exist. If it does then I guess I'm in for a little embarrassment, but I looked at a lot of different dash cameras and haven't spotted anything like this.
