Blessing or a curse
I am not sure if it is actually considered a blessing or a curse to know that data storage can somehow be a permanent facility. It is common knowledge to note that once you upload a piece of data onto the world wide web, you are permanently allowing it to wander around digital space aimlessly and indefinitely. Even if we were to wipe out the entire storage, there is still that piece of data embedded somewhere across the digital era by caches or cookies that work beyond our manual intervention.

Re: Hilarious subject
We are clearly living in the digital era but not every business can thrive solely on an online platform. Some businesses, usually within the F&B market, need to have a physical facility for consumers who prefer to come in to have a taste before making any purchases, especially when they cost so much.

Hilarious subject
Cryptographic world is such a nice domain and place. Specially because it's developed by humans.

At least in our days we are using human developed algorithms.

Why is this subject hilarious?


Because all cryptographic devices, algorithms or schemes have a universal key kept by the owner.

So what's the point of crypting your data if it can be undone?

And more, what's the point of deleting encrypted data as long as it can be undeleted and then decrypted with owner's universal key?

Do you want to get rid of your data, forever? Burn it, melt it down, combine it with another metals or chemical and MAYBE then it's possible to be gone. Unless a latest technology in Recovery field takes molecules of melted data, analyze it and get bits and bytes out of it :D

 

Thank you.
