Untraceable cell phones against unwelcome listeners

July 14, 2010 Technology 2 Commenti

Even though all the song and dance that we are witnessing in Italy about the law that would regulate (that is, limit) the usage of telephone wiretapping would only benefit a few people who would want their dirty business to remain secret, it is actually true that, at least theoretically, there is a problem concerning eavesdropping; that is, our phone calls are at risk because the GSM network, as it has been proven several times, is not completely secure.

Therefore, this places us at risk of having our conversations intercepted by prying ears, and that the information gathered could be used against us. Of course, for those who live an ordinary life, the risk of having their calls listened to by a third party does not pose a serious threat.

But for those who have interests to protect, because their professional activity moves substantial amounts of money, or simply because they want their private matters to remain confidential, the danger of telephone wiretapping might mean losing a big order, or even having to close down their business, not to mention potential family problems.

To protect ourselves against mobile phone interception, it is possible to use a tool that makes sure that no one can listen to our conversations. The Stealth untraceable cell phone delivers absolute protection against the possibility of being intercepted, by adopting a dynamic defense strategy.

To understand how it works, you should keep in mind that wiretapping on our mobile phone can be done not only by the phone number, but mostly by keeping track of phone calls placed and received by a specific handset, intercepting it by its IMEI number, that is, the 15-digit number that uniquely identifies every single telephone. So, changing your SIM card is no use if you are being intercepted, and it would actually place you into a greater risk, as while you think you are protected, you may reveal secrets and compromising details.

Instead, the Stealth Phone, thanks to a modification in its installed firmware, can automatically change its IMEI number each time it is switched on and off, or after each call; the IMEI number can also be changed manually. By doing this, even though you are physically using the same handset, for the network operator (and for those who want to discover our secrets) it will be like you are using a different phone each time.

In the extremely unlikely case that an interception attempt should be detected, your invisible Stealth phone will warn you immediately, by a sound or a vibration. In such cases, all you have to do is close your call and change the IMEI number, either manually or by switching the phone off and on again. At this point, with a new IMEI number it will be like having a new (and non traceable) phone, so you will be able to resume your call where you left it.

Of course, using a Stealth phone does not protect you if it is your conversation counterpart who is being intercepted. Therefore, for those who call always the same person (a business partner or spouse) it is recommended that both use a Stealth Phone, in order to keep your conversations 100% secure and protected.

For more information on operation and different models of untraceable mobile phones, with prices and characteristics, we recommend that you visit the Endoacustica website and request a tailored consulting, one of our operators will contact you shortly.

A fabric that can record or produce sounds

July 14, 2010 Technology No Commenti

As we know, optical fibers can be used to transmit data as light pulses, thus making high-speed Internet surfing as we know it today possible. They can also have some more sophisticated properties, such as the possibility to detect, transmit and play sounds.

A team of researchers from the MIT is developing a particular type of optical fibers which could be used to create clothes that, along from being normally worn, might work as real microphones, to pickup and intercept sounds, but also to measure blood flow and brain or blood vessel pressure.

The acoustic fibers that the MIT research team is working on are manufactured by using a special plastic material, and with a procedure that is slightly different from standard optical fibers, which involves the materials inside each fiber being positioned according to a complicated geometrical scheme.

The molecules of this special polymer are asymmetrical, and thanks to this, it can be defined as piezoelectric, since it changes its shape in presence of an electrical current, just like a normal piezo microphone would do. Thanks to this process (briefly described) fibers can capture sounds just like common microphones would do, and by reversing the process they can produce sounds as well.

In practice, it would be like wearing a microphone, and by connecting it to a micro recorder (or in future, integrating the recorder inside a dress manufactured with these fibers), creating a shirt that can work as a recorder as well, and that might for example sport a USB plug inside a cuff, used to download its recordings directly into a computer.

For those who work in the audio surveillance field, like law enforcement agents of private detectives, it would definitely be a tool worth using.

Robot sentries on the Korean border

July 14, 2010 Technology No Commenti

One day, we might all be replaced by robots that do our job in silence, in an absolutely efficient way, with no complaints and most of all, without joining any workers’ union.
The latest development in this respect comes not from the world of labor, but from the military: in fact, the South Korean government has decided to install, inside the famed DMZ, the de-militarized zone which runs along the 38th parallel and separates the two Koreas, a set of robot sentries.

We are talking about robots equipped with sensors that can detect voice, movement and heat generated by a possible intruder within their operating range, and that in extreme cases can shoot with an automatic gun or throw grenades. As soon as the robot sentry detects an intruder, it immediately sends an alert to its control center.

If the personnel from the center can ensure that the intruder is not a real threat, the robot will not act, but if it is identified as a foe, then an order would be given to shoot and neutralize it.

Currently, these robots are only used near a single border post (of course the name and location has not been disclosed) and should this test be successful, the South Korean government would install automatic sentries, at a cost of 330 thousand dollars each, all along the 250-kilometre long border between South Korea and the no man’s land that separates it from North Korea, one of the most dangerous areas on the planet, as well as the most heavily guarded border line in the world.

Those who might not agree with installation of these robots are animals, which have populated the demilitarized zone taking advantage of the lack of humans, and might find themselves in danger in their involuntary natural reserve.
