Ghost in the Shell
More or less the premise the movie is based on.
(Icon because it seems to be the closest to "The Laughing Man" among the options.)
Scientists in Belgium have tested the security of a wireless brain implant called a neurostimulator – and found that its unprotected signals can be hacked with off-the-shelf equipment. And because this particularly bit of kit resides amid sensitive gray matter – to treat conditions like Parkinson's – the potential consequences …
The last ever dolphin message was misinterpreted as a surprisingly sophisticated attempt to do a double-backwards-somersault through a hoop whilst whistling the 'Star Spangled Banner', but in fact the message was this: So long and thanks for all the fish.
attacks on brain-computer interfaces have shown "that the P-300 wave can leak sensitive personal information such as passwords, PINs, whether a person is known to the subject, or even reveal emotions and thoughts."
Will it be the UK or the USA that first makes these compulsory? To protect the children!
Question: Given that implantable devices have to work within very tight power restraints (due to size and location) , how do you improve security (which has a necessary power cost) without reducing it's working life, which necessarily needs to be maximized due to the inherent risks of surgery?
"Good news! The operation was a success and your tremors should be under control. Just don't get your head wet when you bathe, and don't get any MRIs, and be sure and tell your dentist you have a brain implant. And, Oh yes, here's the battery charger you'll have to wear for at least three hours every day ...
What could possibly go wrong?
... we are not yet ready as we currently would still let companies do such implants. Once they become sophisticated enough to do complex things, you can bet that the manufacturers will use them for advertisement and other forms of attention monetarisation... just like they already did with Smartphones.
A mandatory Happyness Chip, that keeps Big Brother alert of how happy you are with him. And, if not will automagicaly schedule a few quick appointments at the reeducation center, if needs be... I'm sure Mr's Junker and, Barnier would happily pass a mandate to make this compulsorily for the entire EU... Sans its Migrant Workers, who are set to inherit Europe anyway.
Small external power pack with an unobtrusive induction coupling should do the trick.
Rejection of external interference, physical security and robust connections are just implementation details...
Say a 200lb lithium-ion trailer with some of those industrial shielded multi-pin threaded connectors... completely unobtrusive and no more issues about power budget or flimsy connections.
Seems like a plan with no drawbacks to me...
You've never had to deal with a person wearing a pacemaker, have you? Magnetic induction interfaces mean you can't pass many things in life, like microwaves and magnetometers (metal detectors). Plus, externals complicate things especially when the patient is already infirm and may not be in suitable physical shape.
