Biometrics is the form used by banks, some safety equipment and also in the last elections
to identify people from fingerprints.
The hacker Jan Krissler states that could falsify the fingerprint of the German Defence Minister Ursula von der Leyen, using photos taken with an ordinary camera.
This case reinforces the idea, which is advocated by some experts, that biometrics fingerprint is not a safe method, it is worth remember that began it was used in electronic voting machines in Brazil, in the last elections in this country.
Declarations of Krissler, using the code name “Starbug” among hackers, was made at a convention for CCC members (association of hackers Europe), he is 31 and his speech was also broadcast online by the association’s website.
In his speech said that the Von der Leyen pictures were taken in October, and a “close” your finger and photos from different angles was possible to fake the digital minister.
There is much talk in individual data security, but public safety and respect for states by citizen data are the biggest problem.

Networking of things: 5G

So far the connections were being upgraded to improve the performance of telephone between people, but the IoT (Internet of Things) is coming up with 5G connections and this can cause an even greater transformation.
We point in our blog (see smart cities or smart cities) that a greater connection between people and things could facilitate the daily lives of people, but now the idea is to connect us to our everyday objects.
This scenario will be fully ready in no more than six years, and now scientists, governments and communications companies make plans for the use of 5G communication from 2020.
Most experts believe that this will multiply by 10 the connections between people and objects, says Sara Mazur to BBC News: “Before there was talk that by 2020 there would be 50 billion devices connected to the internet, it is now believed that this figure is cautious,” it is research director at Ericsson, one of the communications companies that are developing the 5G.
In 2013 Samsung announced Samsung announced in 2013 that was experiencing the 5G connection to 1 gigabit per second (Gbps), and this means downloading a movie in HD in just one second with this connection, the future has arrived.
Holograms tactile

Dec
The invention comes from the University of Bristol, 
England, where through micro-speakers can touch and feel the images projected in 3D, as news in Daily Mail.
The technique is being called tactile holograms, and the effect is produced by the strong changes in the molecules that make up the air using small speakers that produce ultrasound, the virtual objects created by holograms, sensations in the hands in three dimensions.
The next necessary step now is that the technology integrates conventional holograms production technologies, giving the impression that he can play the virtual object, for example, transmitted video calls from a person, it would be possible to greet her.
The great application thought initially is in medicine, where holographic images of tumors could be played by doctors, helping the most accurate understanding of the size of the affected area, assisting the diagnosis and treatment of cancer.
New technology allows HD 24 Ter

Current technology allows hard drives of up to 3 Terabytes (3000 Gigabytes), but the technology developed
by the Japanese Hitachi now promises an HD 24 Terabytes.
The development made together with NEDO (New Energy and Industrial Technology Development Organization), the technology has developed a breakthrough in miniaturization and organization more productively magnetic grains that make up the HD disks, reaching a size of 10 nanometers (1 billionth of centimeter).
Thereby increasing the density of an HD 8, which now rotates around 500 Gbits per square inch, thus reaching near Gbit 4000, which is a significant increase for a single disk.
Western Digital has launched the new 10TB hard drive in September, the same Helioseal using technology that debuted with the first 6TB WD hard drive in November 2013
Seagate announced a HD 8TB in July.
