Subcutaneous Data Storage

Thanks for your ideas, I think storing an encrypted file on the cloud with an access key in SPARK 2 is a good idea
I also think that in the case of EMP, everything will be fine with him, since he will be under the skin and in the case of radiation, the body’s capacity will absorb him and he will survive. Maybe I’m wrong

& Thank you for the link!

It will either be fine regardless, or it won’t be…. Skin doesn’t change magnetic force

Sad it can’t be checked. in a peaceful way)

Amal has done some basic testing

Enough of a pulse that it physically launched the chip

At that point you have far bigger concerns

In general besides knocking out wide infrastructure power, you don’t need to get worked up about a nuclear generated EMP, EVERYTHING else will be so significantly worse you won’t care

The mental energy spent trying to “emp proof” stuff is better spent trying to be elsewhere… I don’t think you will care about data if you are in the affected area of a strike

I hope it doesn’t come to that, but who knows what’s inside the sick head of the Kremlin’s bloody bastard

Right…

But EMP proofing stuff regarding a strike,
is like making sure you have a life preserver when the Titanic sank…

Sure it’s better than nothing, but it’s mostly a false sense of security…

I am sympathetic to what’s going on over there, but I don’t do false security

I used to advocate and teach emergency preparedness, and nukes are bad
Imagine a Radioactive 10.0 earthquake and everything on fire… and nobody is coming to help

If you are genuinely wanting to be better prepared,
Spend the implant money on a rubber seal half mask respiratory n95, a tyvek suit, a weeks worth of food and water… nothing is going to be up to the task… but it will give you the best chance of minimizing immediate or lethal radiation poisoning… kick that can down the road as much as you can
and then hope you get REALLY lucky and can self extract otherwise your just shit out luck

Any more time effort or expense is just fantasy role play

If it’s time to prepare for a nuke, it’s time to leave

You could write your data to a USB drive, a very small one, in terms of physical size. Or even just a NAND flash chip itself and get it made into a custom implant, or make it into one yourself. People have implanted things WAY bigger than a chip or an entire flash drive into their bodies. Some have implanted entire computers into their bodies!

I don’t recommend you go to that extreme, but a small chip wouldn’t be a problem. You can retrieve it from inside your body when / if needed.

i tested it with an NFCKILL, an nfc specific EMP device

did it on implants that’s were inside of me Ns some that weren’t.

skin does nothing to stop it being fried

The Spark 2 does not allow you to store anything on it; it’s meant to be used with the VivoKey service.

An xDF2 would probably be your best bet but encrypting a small text file and writing it as NDEF should be easier than setting up keys for it.

Okay, trust me on this, i learned this stuff. The body won’t block electromagnetic waves in the radiowave spectrum, (13,56MHz) which is where the resonace of the coil lies. Now do your walls block radiowaves a tiny bit. Your hand? I don’t think so, since the radio still plays indor with you infront of the antenna. Also your handy signal isn’t impeded by your body. The best bet at EMP proofing something is to put it in a farraday cage, aka metal enclosure. The smaller the better These chips won’t survive beeing put into a microwave, and a nuclear EMP will have similar strenght. However it’s nontheless a good idea to have the keys on an implant since then you won’t loose them. However if you are worried about emp’s keep a copy of it on a metal enclosed SD-Card, which also can hold your data directly by the way.

Also check out the EMP section of this:

You may be right, but it’s important to note that electric fields are distinct from magnetic fields in a few key cases, such as RFID implants. The magnetic component of the EMP blast reduces in magnitude at the inverse cube of the distance, whereas the electric component of the EMP blast reduces at the inverse square of the distance. In addition, the LC tank circuit in these implants acts as a band pass filter only allowing a small frequency range to enter the chip (from my VNA testing 13.56MHz ± 1.5MHz). There is also ESD protection built into the silicon die.

I think many people overestimate the effect of a EMP.
They are not very well suited to destroy every little electronic device in a area.
Instead they aim to destroy the large scale infrastructure like power grids, communication networks and communication equipment with antennas.
If are close enough to absorb enough energy n your x-series tag to destroy it, the state of your implant probably isn’t much of concern for you anymore

This is what I was trying to point out

But “EMP kills everything electric” is a persistent trope

Like tampons for gunshot wounds, microchips are mark of the beast, wasp spray = pepper spray, frozen paintballs hur hur,

People usually prefer easy soundbytes to complicated details

I want to solder (a bag - a case) for personal electronics, tell me who knows what size of the cell and the thickness of the copper wire is optimal for this task? I plan to buy a mesh, but I don’t understand what cell caliber is right for my purposes as accurately as possible Condition to save devices and data in case of EMI. There is already a ground cable in the basement of the house and I plan to solder it to a box of copper mesh with electronics inside.
In Ukraine, on August 23-25, Russian Nazis are planning to arrange a missile armageddon, you can expect anything from these bastards.
I want to insure myself a little

What you want is called a Faraday cage. It can be made from almost any kind of metal, but people usually use foil or fine screen.

I used to think doomsday preppers were a little nuts, but the last couple of years have proven them a little wiser than I thought. The good news is they’ve done all the research for you.

I kind of like the last one. It’d be something that provides physical and enviromental (water) protections too.

Thanks buddy, in theory I know about the faraday cage, I would like to do it qualitatively as they say with guarantee)
I’m currently using an old metal toolbox in which I drilled a hole and bolted on a ground cable. Should work in theory
Thanks

You want to close any gaps that are the EM wavelength or larger. For broad spectrum use, that means the smallest gaps possible. Look at that last one I posted. She uses tinfoil as a gasket to seal the gaps in the lid. She also lines it with carboard to provide a barrier against the electronics touching the metal.

You can also get aluminum foil tape to cover the gaps. Just make sure the aluminum portion is connected as the adhesive doesn’t conduct.

Simply put, what I’m trying to find out is the maximum allowed cell size when using a copper mesh. i try to explain, I have a backpack in which I want to place a copper (flexible) faraday cage.

To block an em wave, the cell must be any size smaller than the wavelength of the em wave. So first you have to ask what frequencies are you trying to block? Then figure out the length of it’s wave. Finally, find material with holes smaller than that.

It might be easier to say " I have mesh fabric with holes at xxx size. What wavelengths would that block?"
