The optic USB-stick gives a new type of data security

The optic USB-stick gives a new type of data security

Transporting the stored light is one of the things, which are opens new opportunities for a new and safe way to store data. The magnetic data mass-storage can read to the computer without the owner of the data storage notices it. And that thing makes those things problematic. If the data is read to some supercomputer it can start to break code. The owner of data that doesn't even know that the data is stored. The USB-sticks are used to transport the highly secured data like cryptic keys to systems. 

Those cryptic keys can be the images, that are stored in the encrypted area, and they are used like physical keys to data networks. And if those keys are copied, the hackers can enter the system without nobody notices them. 

If we are thinking of traditional or USB-storage what can be encrypted, the problem is that the similar systems, what are observing the neural electricity of the brains can read the bits that are stored in the USB sticks. Those systems are basing the superconducted antenna and extremely sensitive technology. So when the encrypted data is read to the computers, the code-breaking computers can start to operate with that.

That kind of system, what reads data from the USB-stick can be in the customs or it can be even portable, and the data from USB-memories can read that the victim doesn't even notice that thing. So the stored light could solve the problem. If that thing doesn't require the external energy, this is the revolution of the data systems. 

The optical USB-stick could be basic like a thermos bottle, where are mirrors, and the laser ray will jump between those mirrors. When the data is read to the computer it is lost from the stick. And the owner notices that the data is lost. 

Researchers have created a way to make an echo of the 100% of the light. This thing requires that the mirror is cooled to the zero Kelvin degrees, which makes that mirror stable. And if the system uses very small or nano-size mirrors that help to keep the surfaces of mirrors stable. That means that we could stop the laser ray between mirrors, and store the data to that light. When the system needs to access in that data the laser ray simply turn to affect the light cell, and then the data is transferred to the computer. 

By using nanotechnology there is a possibility that researchers could create the USB-stick-size thermos bottle, where is extremely small mirrors, where the laser ray is jumping between those mirrors. The thing is that the extremely small size of the mirrors is making the system stable enough. And when the data is needed to read, the mirror just lets the laser ray enter the computers.

Could this be the thing, that some people don't want you to know about zombies?

Could this be the thing, that some people don't want you to know about zombies? The simplest way to control zombies, which are made by using tetrodotoxin, which is called "zombie poison" is to use the automatic dispenser, which is normally used in diabetes treatment. In this case, the dispenser would be loaded by using tetrodotoxin. If the level of this poison is right, the person would be totally under the control of other people. And if the system cannot detect this poison there is a possibility to make the laboratory experiment when the staff will follow the decrease of the tetrodotoxin, and then the system can use a simple clock, which will inject poison to the body of a victim after a certain time. This would be an effective tool in the hands of military and counter-terror operators. Those zombies can be captured enemy operators, who will send back, and then they just kill their ex-partners. By using genetically engineered bacteria could be possible to create t...

Terrifying visions of genetic engineering.

 Terrifying visions of genetic engineering.  The modern Hounds of Baskerville ABW:s (Advanced biological weapons are the modern Hounds of Baskerville. The term ABV means the animal which is genetically engineered. And which is controlled by using some interactive electronic systems. There is a possibility to connect the action camera to dogs collars. And transmit commands to that animal by using electronic systems. Spoken words can use to the commands.  Or they can be a series of sounds that are stored in the sound files. When the operator activates a certain file that sound means a certain command to the animals. There is the possibility to automatize some commands by connecting the system to the image recognition tool. When the action camera sees something that is stored in the memory of the computer. That system sends the coded order to the animal.  Nanotechnology and genetic engineering are the most lethal combination in the world. The ABW:s (Advanced Biological ...

Facebook and dominance of the media.

The position of Facebook is dominating and that causes concern. Facebook is a well-known and commonly used service. And that thing causes that the information is starting to pile up in that service. That information contains data that we might want to hide. Facebook is a network-based service that can use for many purposes from marketing to intelligence.  Facebook was down and the thing cost about half a million dollars per hour to that service. That shutdown has shown how dominating that service has been growing. Facebook is a powerful tool. It can use to track the networks of people.  Artificial intelligence can show the network map of the people who are using that service. The data that travels between certain members of the network can show how often those people are contacting each other. There is a lot of criticism against Facebook but the fact is that everybody is using that thing.  The attitudes toward Facebook are conflicting. People are criticizing that service ...
