How wise is it to ban Google in China? Look at what it did in the Russian-Ukrainian war, and you will understand.

When it comes to search engines, what comes to mind first? I believe that Baidu is the first thing that many friends think of. In China, Baidu is indeed one of the oldest and largest search engines. But the most widely used and user-friendly engine in the world is Google. Do you know why Google should be banned in China? What are the considerations behind it?

At present, only a few countries in the world are not allowed to use Google. Not only in Russia, but also in 95% countries and regions in the world, Google has the ability to discover and publish their secrets. On Google Maps, we can see almost any corner of the earth, and even the carrier aircraft on the American aircraft carrier moored in the port.

In fact, Google came to China market as early as 14 years ago, ready to make a fortune here. However, the arrogant Google completely ignored the relevant ban in China, threatening China's national security and information security, especially Google Maps, which is the key target of the ban.

Despite the ban, many details of China's geography can still be seen on Google Maps. Will this information threaten China's national security? To understand this, we must know how maps work in the military and the difference between military maps and civilian maps.

Military maps are topographic maps, and civilian maps are geographical maps.

On the topographic map, the topography of a place will be marked in detail, and the three-dimensional scene can be restored according to the corresponding knowledge; However, these things can't be found on the civil geographic map. They will only tell you the specific place, and there will be no more topographic information about this place. For example, it will only tell you the location of villages and cities, but it will not tell you the terrain of villages or cities.

Militarily, the function of map is mainly to facilitate the navigation of troops, planes and missiles, which involves a problem, that is, the coordinate problem. Every corner of the earth has its own unique coordinates. If you only give you the topographic map of this place, you can't be sure where it is, but if you give you its coordinates, you can quickly locate and accurately strike under the guidance of the coordinates. Therefore, topographic map and coordinate information are the two most important parts of military map.

In 2005, Google Maps entered China and became popular with its powerful navigation function. The netizen exclaimed: It's really useful! Only four years later, in 2008, a paper ban completely ended the history of Google providing navigation services to China people. Why? This has nothing to do with what Google did.

We must know that although four countries have the ability to photograph all corners of the world at present, it is much more difficult to lock the coordinates of each corner. In order to get a definite coordinate, there must be a signal transmitter on the ground and more than three satellites in space for positioning. Therefore, in order to obtain the position coordinates, we must first have a signal transmitter on the ground. At this time, ordinary people's mobile phones have become the best ground terminal for Google to collect location information.

At that time, more than 300 million mobile phones were using Google Maps every day. In the process, Google took the opportunity to collect important geographic information and coordinate information of China. Not only that, it will also issue a bounty mission, and you can get a bounty by taking your mobile phone to a specific location and turning on the GPS. The sensitivity of these locations is self-evident. We should know that the large-scale surveying and mapping of a village and city must go through strict examination and approval, not to mention these sensitive areas. In the past few years when Google entered China, related illegal surveying and mapping cases emerged one after another, many of which were related to Google. However, in Russia, Google is not subject to any restrictions. This time, all Russian secrets have been made public by Google, which shows how wise China is to ban Google.

Is it possible for Google to obtain confidential information by deciphering the electronic map currently circulating in the domestic market? This involves an important means of modern maps-map encryption.

As we said before, accurate positioning requires coordinate information, so on the electronic map circulating in the domestic market at present, the geographical position and coordinate information are actually inconsistent, that is to say, if the position is located according to the coordinates given by the map, it is not the position marked on the map at all. This is because all maps must be encrypted by the state before being published, and the coordinate information has been modified. If the enemy uses such a map, there will be a situation of "pointing east and hitting west". Unless there are a large number of terminal devices on the ground, no company can break through China's encryption means and recover the correct ones from the wrong coordinates.

In the 4th year when Google was banned in China, an online car rental company was born in 20 12, which provided a new means for Google to collect information about China. In 20021year, the company was banned from listing in new york by the US government on the grounds of preventing national data security and protecting citizens' interests. Behind it are the action tracks that the company plans to provide to all networked cars in the United States and China, as well as the real-time images of the camera inside the car. You know, with these, the United States can calculate accurate coordinates, and with the photos taken on the internet car, China's secrets will be unobstructed in the American sand table. With these data, the US military can break away from "pointing east and hitting west" and realize "pointing where to hit".

It can be seen that it was a wise decision for us to ban Google. When there is a conflict between the two countries, the casual actions of ordinary people will become knives handed to others. So, is Google still fragrant?
