-   All files should be encrypted and can’t be accessed or hacked.
-   When the computer is being shut down (because of damage or by loss of power) everything is lost, the PC will not run anymore and none of the files will be accessible any more. ...

I'll address these 2 points together since they seem to converge on a common theme, controlling the content. I'll try to stick to
the broad strokes here.
1. For storage, a Solid State Disk might be your best bet for longevity.
2. Encryption could be done at the disk level or file level.
3. When first booted, you would have to type in the code for decrypting the files. Key disappears upon power failure since it's in RAM.
4. Software disables keyboard port after decryption code is entered.
5. Decryption code could be used to make the drive accessible or to decrypt the video files as required.

Yes, this type of "security" is something that i'm looking for.

How easy is it to set up something like that. I have no idea if it is easy or not for a programmer to alter Linux in such a way. I'm willing to pay somebody to do this but don't know what kind of budget i would need.

Hi flood
Something like  cryptsetup  might work for you:

Encrypting at the partition level probably makes the most sense, i.e. the partition containing the video files is inaccessible until
the key is entered. You probably need a separate partition to boot from. I'm sure there are more knowledgeable members on
the forum when it comes to disk encryption. Maybe one of them will chime in.

Disabling the keyboard could be as simple as unplugging it and gluing the port shut with some epoxy. No code required.

.. Hope your project is not anti-social due to so much secrecy and security features , and you are not attracting attention of global spy and security agencies. ... Just kidding ! :)

... Many years back ,  I had helped an Engg student with head - sector - tracks and BIOS time stamp based encryption algo to encrypt a 2GB HDD , which none was able to decrypt without an unique key. The key was programmed to expire after 60Hrs.
 ... Now-a-days one can google for many decent Disk level encryption algos ready-made on net , in many languages like C , C++, Assembly etc.

 I think , there may be some projects available on net which emits some radio wave signals at perticular intervals thru some hardware gadgets and helpful in space technology.
... Some IoThings remote controlled projects are already available in technology forums. Pl google for it. Final year Students and Teachers in Tech Institutes  in your local area / city can be your best bet for quick and practical help to achieve your goal within your budget.

...Best Wishes , if the project is of any help to public in general and yourself in perticular ! .. :)

Disabling usb ports is pretty easy, it was just writing a value to some file in /sys IIRC. Being art, gluing the ports shut would look nice in addition to the software lockout.
