I was watching a televised production about the disappearance of Zoe Campo from Lubbock TX, (a few years back). About all the authorities seem to have to go on is the last ping from her cell phone, and later finding her car, but not the cell phone. They looked at her Facebook stuff, and accounts of persons surrounding her life. So far, no trace of Zoe.
What can engineers to to help? Can we make a cell phone app that would keep a young (or old) woman's cell phone camera, and/or microphone up and running, transmitting to a "safe" storage in the cloud? Mass storage would probably be one of the issues related, but could there not be some discriminatory software running that would hold at least one day's worth of pics, video, audio recordings, and telephony, but that would automatically roll off, unless triggered to hold in memory by some means. I do not know what that means would or should be. Nearly anything I can think of would easily be surmounted by a crafty criminal.
Any ideas, suggestions, willingness to create something new that could be a really valuable tool for police?
