It is better to declare the SNS account as one of the emergency contact means

Good morning. I expected that it would rain yesterday, but not even one drop. It was so humid and hot last night that I opened the window a bit, and when I went to bed I became cold at dawn and closed the window in a hurry.

People who do secrets in the real world

As a recent trend, having multiple accounts seems to be popular. It seems that there is a normal account and a back account. I don’t understand very much, but the surrounding young people talked in common about how to use the back account and how to block information in LINE. The fact that such abstract rules are understood and used is evidence that IT literacy is widespread.
I think IT literacy is an extension of real literacy. People who do secrets in the real world do secrets in the IT world, and those who enjoy in the real world should have many followers in the IT world.

In the United States, the filing of an SNS account is required to apply for a visa

The US Department of State has made it one of “to strengthen our process to review these applicants and confirm their identity.” Visas are required for long-term travel or migration from countries other than 38 designated countries, but SNS accounts must be declared. Visas are exempted from 38 countries and regions within 90 days of stay.
The breakdown of the SNS account declaration is the user name, phone number, and e-mail address of Twitter, Facebook, etc. used in the past five years. It is estimated that it will be applied to 15 million foreigners a year.
Well, from such a noisy world, the government must do everything it can. However, the move seems to be somewhat discriminatory in that it targets travelers from countries other than those to which the United States is friendly.

From the point of safety confirmation

Recently, the fear of terrorism is threatened by serious pretending reports, children’s animation called violence as justice and strange and unnatural labyrinth incidents. Opinions that oppose this are often overlooked. However, if you have to be contacted urgently, if your emergency needs to be confirmed, etc., you will receive useful information if the government knows your SNS account.
Conventionally, it takes time and effort to confirm the safety of the traveler, but if the SNS account has been declared, it suffices if the message is sent to the terminal possessed by the traveler. It’s really fast and cheap. So, from the point of safety confirmation, it is better to declare the SNS account as one of the emergency contact means.
Especially when travelers need to return home quickly, especially in the case of an emergency such as a disaster, it is correct that the government office uses SNS to make the necessary instructions known quickly and in large quantities. If you don’t have SNS, the trouble will be bigger. I think there is such a positive side.

At the time of the disaster, instructions such as direction and place of evacuation are not easily transmitted. Screaming with a loudspeaker has its effect limited. However, if the information is broadcast simultaneously to the registered SNS account, many people will be led to the safe zone quickly. I think that SNS account declaration is effective as a disaster countermeasure, what do you think? I know that there is a humanitarian downside in which personal information is monopolized in account declaration. I would like to discuss the problem together.
About GPS, if we wear GPS, will human rights be violated? I do not think so. Rather, I wear GPS. So, someone please monitor me. Because, for example, when I was in a car accident suddenly, I do not want the tragedy that nobody knows me lying on the road to happen.

No matter how much we benefit from IT, the owner of IT is us. Real We use IT. It is not the opposite. The accident of the computerized system occurred, but it is the real us who kept using the system 30 years ago. So there is a fault in us for the accident. It is natural, though. Yes, have only one account. Today’s post is over. Thank you
