But how you will identify it if you are about to retrieve the wallet? You have to put some hint of doing this. This came to my mind but I'm very easy to forget and my memory doesn't works well now.
The "story" part gave me an idea. Maybe it can be encrypted into a poem that can be then memorized. Would be longer but seems easier to memorize than a random sequence of words. Thanks for the suggestion.
Wooah I remember someone suggested and created this type of encryption to his private key. Making a story with the use of your private keys will give confusion if someone accidentally sees your PK's. Thanks for reminding me about this type of sequence and the story thing. This is familiar to me and it's a good way to protect it that way, you don't have to memorize it you only need some hints on what are the most important words.
Yeah, I'm thinking along the lines of a number sequence you can easily remember (special dates, etc) and using that as key to extract the words form the sentence. Am starting to read up on cryptography now. Interesting stuff.
Here's a total paranoid way of storing it. It was (and probably still is) used a lot for message coding by intelligence services of many countries, so old, but still effective.
Take a book. Any book you like.
Find all the words your mnemonic phrase contains.
Mark their location using page-paragraph-word number combination, ie 120826 would mean page 12, paragraph 8, word 26.
As a result you will have a series of 6 digit numbers which you are free to store on your Google drive, email to yourself or paint on your roof
Without knowing what the key book is no one will be able to decipher it.
That's quite cool. I think the good thing about is is that you can use any book, there's less danger of you losing it since many books are available online, you can just download them if you lost your physical copy and then just do a pen-and-paper solving.
You mentioning books reminded me of a technique I saw in a Kdrama. To decipher the number sequence, basically the content of the book is written on a grid. The number are actually pairs showing the coordinates in the grid so they'd spell out the words. I suppose the hard part is keeping the sequence. Most people are not that good a remembering strings of numbers.
