Geek help needed). How to send a letter after 15 years?

Question

Email

Hello! So friends, there is not quite a common question. The conditions of the problem are as follows:
There is a father and his child aged 2.5 years.
For certain reasons, it is necessary to make sure that after about 15 years the child receives a message from his father. And I got it guaranteed. And to be more precise, I got access to the account on which certain information will lie.
A prerequisite is to set up once and never again be able to roll something back. Roughly speaking, I sent it now and the addressee will definitely receive it, no matter what you do.
So the question, dear experts.
How to do this in order to be as sure as possible that the message will reach?
It should be taken into account that the services of delayed mail sending may be closed, it’s just that the chrome plugin may not work, since the account will most likely be reset for being inactive for a long time.
A cell in a bank with passwords will also not work, since the bank will not look for a grown child with a request to go to them. In addition, suddenly the child can move.

Answer 1

the task is similar to this one: guaranteed to live another 15 years.

Answer 2

Empires fall in 15 years.
In half a year, humanity may not be.

Answer 3

1. Come up with some number combination, say 52341
   By default, we accept that it is impossible to crack the safe. Gold can be replaced with any other reward.
   The bottom line is that after 14.5 years the shelf life will end. Bankers will not cut the castle right away, usually they wait there for 2-3 months, trying to contact the client. Having opened your cell, the banker will receive motivation, no matter what it will be - gold, bonds or something else. The main thing is that this something has not lost its value in 14.5 years. Another 2-3 months they will look for the addressee. The result - in about 15 years, your message will most likely be brought to the final addressee.
   The only bottleneck of the algorithm is how well you can hammer the key sequence given on the safe into your child's head.

Answer 4

in my opinion this is done through lawyers (or notaries?).
you can search for a service, but there will be fewer guarantees than if it is a real paper letter from a living person.

Answer 5

In fact, the task is very easy to solve. Non-geek solution.
Option 1 - if you have enough money, find a normal law office in New York, London or Paris (preferably the bar + notaries together), agree on a fee (possibly a partial prepayment and partly after the transfer of documents), hand over to them this is all that you want to pass on to the child and that's it. As the years go by, some kind of duty lawyer or notary will come to an already adult child and bring what they need.
Clarifications:
1. Partial payment can be made through a bank, with a guarantee, a deposit or something else, there are different options.
2. The office can monitor the place of residence and other details of the child's life, for example, once a year.
3. Instead of New York / Paris / London, you can Berlin. In the US and Britain, plus is the COMMON LAW system, where all such agreements are possible and they can even be defended in court. In France, a plus is a historically strong notary, who is also used to such expressions of will. Well, Germany is just a country ordered to the details and the system will not collapse.
2. Option 2 - if there is not much money, you can do the same with Russian lawyers. Although the issue of reliability and durability is more risky.

Answer 6

"one of the strange beliefs of our techies is that the Lord God created communication channels, servers and operating systems for them forever, which means that you should not think about options when they suddenly stop working"
from here

Answer 7

There are a fairly large number of services that allow you to send letters to the future, including paper ones, for example https://future-mail.org/

Answer 8

This is done with the help of the so-called. trust fund. My daughter has one for 20 years. And self-replenishing. After 20 years, the fund is unfrozen, and she gets the opportunity to withdraw money. At the same time, in the documents, you just need to specify an additional line that they say there is such and such there, and the password is this.
But again, the letter will receive, and the second question is the account. It’s much more complicated here - you can’t even be sure that Google will live that long (what if?) So you can buy hosting that, well, it’s definitely not going anywhere (from the state registrar) and set up payment in the bank’s pay account to pay for hosting.

Answer 9

My son is 7 years old, and 2-3 years ago I thought about solving such a problem. I thought about it because I will live or not - a matter of good luck in life. I wanted that if "what" is with me, then the son would not stay in F * in which case. I bought a decorative lamp, it is very similar to the "time capsule" that is buried in some US schools. I threw out all the insides, put a few documents + a letter + expensive watches, jewelry, and when I went to the mountains, I found a place and buried it. I thought to give jewelry with engraved coordinates. But here the question is that the rings will not fit - the child is growing rapidly. Jewelry can be lost and you need to think about some kind of "encryption". Now the child knows by heart all the coordinates, but how to explain to him what it is is an open question.
I hope we go to his 18th birthday together or he rolls himself later,
PS: I came up with an ingenious thing while reading the answers. What remains with the child and is rarely lost: Birth certificate
This point is worth considering.

Answer 10

as a joke: leave a will and die.

Answer 11

Rent in different data centers from different vps hosts (if you rent shared hosting, then probably in 15 years the version of the language will be updated and the script will not be executed, and no one will reconfigure anything on vps without you) for 15 years and install a script on it that, upon the occurrence of a certain date will send a letter.
Even if one or more hosters fail, some copy of the script will complete this task.

Answer 12

I did not understand, but what is, so to speak, the identifier of the addressee in this mortal world?
The question has been tagged "e-mail" (and therefore a lot of answers are about exactly how to send an e-mail to the future), but this is just from the bullshit, right? Where does a child of 2½ years old get an e-mail address, and even one that is guaranteed to remain with him for fifteen years?
Apparently, we are talking about a fuzzy type identifier: such and such, son of such and such, brother of such and such, grandson of such and such, nephew of such and such, currently living there.
And this task at the present stage of AI development can only be set before a living person. And here, in general, there is nothing complicated. 15 years is not 150 - dozens of people that surround you after 15 years will still be quite sane and in a sober memory. Of course, we must remember that a person is mortal, and suddenly, and indeed can fail, well, this is also not a great problem, if the information is propagated (and it is propagated) - ask many people.
I believe that it is quite possible to find even completely strangers (and for the reasons described below, it is precisely such that are desirable) who will take on such an assignment. I would, say, take it; although for what reward I don’t know yet, maybe even out of pure interest. :-)
The problem is different - you seem to have confidential information. If so, then it is obvious that it is necessary to encrypt it, and in the simplest case, transfer the key through other people who are not familiar with the former.
If you find this not secure enough, then move on to the “what you are” method. Classical methods - fingerprints or retinas will not work here, because this is not authentication, where you can make some error in the comparison - we need perfect reproducibility.
Such reproducibility is provided by the genetic material; a typical analysis of 16 loci, as in a paternity test (made from a mucosal smear in any DNA laboratory for no more than a hundred euros), provides information (though not random, but rather unique) I won’t say offhand exactly how much, but definitely more than 128 bits (each locus has two alleles, there are at least two dozen common “values” of alleles for each locus). It remains to turn it into a key, and send the instructions for reproducing the key to the addressee in the same way as the message itself.
However, this method is still unstable against a malicious intermediary - having found a person, it will not be difficult to get his genetic material - it is enough, say, to steal a toothbrush.
Therefore, the encrypted message itself and the instructions for obtaining the key are still transmitted through different groups of intermediaries.

Answer 13

Consider the task not as a technical one, but as a psychological one.
Condition. Someone needs to hand over a letter in 15 years.
So this someone must be mativatirovan.
Decision. Promise the family, because non-relatives can fight, a very generous reward that they can receive if the letter is delivered. Secure it in a contract.

Answer 14

Some kind of nonsense, 10 years ago people shied away when someone decided to say a whole Gigabyte of information from the network, and now an ordinary film weighs over 10GB. This I mean that it’s really possible to make some kind of forecast here, you don’t even know what will happen to the country in 15 years, let alone what awaits us in technology. Maybe YouTube and Facebook will go down forever, and so on, and even more so, some kind of service, even if it’s super cool for sending letters (if, of course, you can send it after such a time, here, in 15 years, the servers with all the letters will change 5 times and no one will store it will be) So it’s better not to bother, I think, and either immediately say or give a letter to a person who will give it back in 15 years

Answer 15

Buy multiple ssds. Encrypt a container or section with a message on these disks using several encryption methods. Next to the open section put software with instructions for decryption, but without a key. Distribute discs to trusted friends.
The key is to tell other trusted friends who will never cross paths with the former. And ask him to give the cipher to his son on the appointed day. And a few days later the disks.

Answer 16

It seems to me that it is better to do this through lawyers. And not Russian (the jester knows what will happen in 15 years), but foreign, and several. There, of course, there is also a non-zero probability of problems, but still.

Answer 17

I know. The child is 2.5 years old.
Bury the letter in another city.
Stuff a child on the back \ arm \ leg \ ass with a tattoo with a map of the area.
in 15 years he will be 17.5 In half a year he will be of age and will be able to pick up the package.

Answer 18

The author, it has already been said here that Google \ Facebook \ Internet \ countries may not be in 15 years. But I think that for reliability it is still worth using this data transmission channel. For greater reliability - twice. You find 2, 3, 4 cheapest hostings where there is a mail server and where you can install a script that can send a letter / sms at the right time. How much will cheap hosting cost? 1000 rubles a year? Pay a couple, three. Total 24,000 rubles or 300 bucks. You might find it even cheaper. The next question is: where to send in 15 years? You can use the real emails of close relatives to whom letters are sent (the more the better). Which, in turn, will tell their son that you have received a letter here. Risky? Risky. But you have an extraordinary task.
And then: I don’t understand why you are looking for some kind of service? Why not turn to people with this request? Yes, not to one. I assume that the information can be very personal, but it can be thought through somehow.

Answer 19

you rent a VPS server for 15 years, set up cron, write a script to it that sends an email. that's all. I can give you a script... you can also buy a domain and post something using a secret url, you specify the url in the letter.

Answer 20

It is worth looking at the problem from a different angle and simplifying it.
For example, instead of sending a letter in 15 years, it is better to send 15 letters in a year. This makes the task more difficult for you, but easier for the performers. This increases reliability and the likelihood of successful execution.
15 (plus or minus) sets of software are being made. One of them provides access to the message for the son, the rest provide access to each other. It turns out a chain.
There is a reliable person or several. They will receive a letter from the first script in a year. there will be a task, according to which the executor must run (and most likely just check that everything works) the second script and find the next executor.
A year later, the second script will give the second group of performers the TOR for deploying the third script, as well as a notification to the first group of performers (so that they control the work of the performer they have chosen, you never know).
Everything is repeated in a cycle every year. This is how we protect ourselves from irreversible changes that could happen in 15 years. Plus, the number of performers is growing exponentially, which improves reliability.
Part of the task for the performers may be to track the situation of the child (where he is, where he moved, whether he changed his last name). Tracking should be implicit. So that the performers do not know about the child.
Supervision may be for the mother, for school teachers and other people who have contact with the child. Because the circle of these people is unknown in advance, there is some difficulty in finding them every year.
Each new performer will have more and more information, but will never know everything.
The feedback to the already fulfilled performers is also important - their interest and curiosity should be maintained. They insure the stages that will be after them.
If possible, it is worth excluding material remuneration of performers.
In general, this is a very cool task at the intersection of technology and social engineering.
