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