Selective encryption reduces security by making it easier to find the data worth decoding. For example a check image would highlight a target of interest - even if part were encrypted. A clear text online order would provide valuable contextual information even if the credit card information were encrypted. With overall encryption, a lot of effort can be devoted to decoding what proves to be useless information.

Sounds like a good approach, but I wonder how much is saved (on average - I am sure it is media/image dependent) versus what additional power is used in the initial analysis? Looks like it works but getting major acceptance could prove a challenge.

Content based encryption sounds like a good idea to reduce power consumption. I would like to know more technical details of the idea such as how much power it saves.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
