Information Security Theory

【question】

Is it okay if I don't worry about being exposed?

When I was looking at the internet, a former NHK announcer was a member of the mistress club and was featured.I'm honestly worried.

Is it safe to manage personal information?

Thank you very much for your question.

The strongest information security in modern times is to not be hated.

Any kind of security is almost meaningless if people don't like it.I have no doubt that the strongest modern security available to the average person is not to be hated.

 

Information leaked by hacking! !I don't mind

Computers and machines are by no means perfect, but they are overwhelmingly infallible when compared to silly devices like humans.

Now, let's say that the questioner did papa katsu and then became an announcer.

As a matter of course, the questioner who became the announcer caught the attention of many people.

Of course, there is a high possibility that some of them are people you met when you were working as a dad.and will disappear from the announcer column of the homepage.

Information leakage, which is said to be a so-called scandal, is basically lost in such a flow.I don't know how secure Universe's personal information management is, but even if it's Pentagon-level security, that would be a trivial matter.

In addition, if someone witnesses the scene where the questioner enters the hotel with a dull uncle, he may find out from there.At that level, there is nothing the universe can do anymore.

Furthermore, as long as you sell yourself as a product, you need to disclose your information to customers to some extent.

If the questioner is a university student, there may be university professors among the customers, and if he is a member of society, there may be a boss at the company.That's how it happens.

At least compared to the chances of the Universe database being hacked and exposed, the chances of it being leaked by someone close to you are probably hundreds of times higher.

Devalue your information

From the Caesar cipher used by Caesar in ancient times to the modern RSA cipher, cryptography is considered in terms of "cost".

All ciphers can be deciphered.In other words, an undecipherable cipher cannot be deciphered by allies, so it cannot be used as a cipher.Therefore, when creating a cipher, we consider the cost of decryption.

For example, let's consider RSA encryption, which is the mainstream of modern times.This cipher uses multiplication, so if you do a lot of calculations on your computer, even I can definitely solve it.

The problem is that time.The number of multiplications is so great that even with the world's best personal computer, it would take a little less than a year to calculate.

 

For example, if I hacked the questioner's passbook out of desperation, what would happen if there was only 100 million yen in it? The amount of money you can get by running a supercomputer for a year is only 1 million yen.This cannot even cover the electricity bill of the supercomputer.

In this way, in information security, it becomes important to increase the cost of decryption against the reward that can be obtained.The value of the questioner's bank account is almost zero, but if this is confidential information of the Pentagon, it will be worth stealing even if it takes a year or two.

Then, how much value is the information that the questioner finds out, that is, the questioner is doing dad activities?

There was a clear value in the information that a certain announcer had a mistress contract.I don't know the specific amount, but if you sell it to a weekly magazine, you'll probably get some pocket money.

 

On the other hand, what about your question?

Even if I obtained the information of the questioner, even if I sold it to a weekly magazine, it wouldn't even be worth 1 yen.In other words, the value of the questioner's information for me is almost zero.

But what if I really hate the questioner?

If you're a college student, you can think of a variety of effective ways to use it, such as selling it to the university, threatening to shake the money, or sending it to your employer so you can't stay at the company.

If the questioner, who I hate so much, has a misfortune, I might think that 100 million or 1000 million would not be a waste.

It is in this sense that the strongest information security is not to be disliked by people.

 

The value of the questioner's information jumps up by being disliked by people.If the value of the information increases, it will be possible to spend a huge amount of money on decomposing it.

And in modern times, it would be extremely difficult to protect information if it was seriously targeted.

The number of people who don't like the questioner.That is the degree of danger of your information.
