Ecological destruction of data

[The text was translated automatically by Google Translate] Polish law as well as common sense, requires that selected by our method of data destruction prevented their restoration. It is very difficult that most of the available methods of destroying not give such a guarantee, and the only difficult and boosts the recovery process. Even the smallest pieces of media data can be recovered, and the never sure whether or not this happens is these key figures who were trying to protect. This means that the only way to guarantee data destruction is total physical destruction of media, currently only achievable with the help of two methods: chemical and thermal. At the same thermal method is neither mobile nor ecological - causes the destruction of not only data, but also precious and valuable commodity, which sometimes just is not irreplaceable...

The requirements for the desired degree of destruction of data, specified in the relevant Polish legislation (including in the Ministry of Internal Affairs and Administration of 29 April 2004, the Act on the Protection of Personal Data and a dozen other regulations), present even on a fundamental level security of personal data, meet currently only two methods of data destruction, namely chemical and thermal. These regulations require damage "devices, disks, or other electronic media containing personal data (...) in such a way that absolutely prevents reading them."

Although the same rules we do not find the exact answer what exactly does the term "absolutely prevent" it, due to the fact that most of the currently used methods, including overwriting digital, mechanical shaving, degaussing, etc., does not prevent the read data but only more or less difficult and / or increases the cost of their reading, it can not meet the above requirement. The Act on the Protection of Personal Data determines penalties - even imprisonment - for those who made ​​it possible (even unintentionally) access to personal data, so people do not destructive data effectively expose themselves to criminal liability.

In order to effectively and permanently destroy the data must be destroyed even the smallest piece of media - since 2004 we already know that it is possible to recover data even from microscopic particles disks (Read more about it: Link) . Such a total destruction is only achieved by dissolving the carrier to form a liquid - by chemical LiquiDATA technology , or by dissolving the carrier due to the high temperatures, exceeding 1000 degrees Celsius , which is unavailable in the home . In contrast to technology LiquiDATA , thermal method is not mobile - furnace is not able to come to the client, which means that there is a risk of data loss during transport, it is also ecological - while burning discs are irrevocably destroyed not only data but also valuable raw materials from which the carriers are built, and in addition to the atmosphere of pollutants emitted are many particles, including hazardous.

The question of irretrievable loss of resources is so important that, Thomas Graedel of Yale University, and his team, after analyzing the elements used in the manufacture of mobile, warns that if nothing changes, in the near term will be physically impossible to manufacture modern gadgets (and You can add that as well and storage media). Although his research focused on mobile phones, its results can be generalized into other media as they also consist of elements that can not be replaced.

According to the Graedel research team to produce phones are used 62 different chemical elements, with 12 of them irreplaceable: rhenium, rhodium, lanthanum, europium, dysprosium, thulium, ytterbium, strontium, thallium, magnesium and manganese, in the case of other the effect of the use of substitute elements is either unexplored or unsatisfactory. The word list of the disks overlap - and, in view of the larger dimensions, it is used even more such elements, including rare-earth metals.

Rare earth metals are not for nothing called "rare" - on Earth, they are few, including a large part of them is mined in China, often at great expense to the environment. Another problem is the limited export of these metals from China - in August 2010, they announced a reduction in exports by over 50% and the creation of strategic reserves.

According to the data provided in the course of debate on this issue in the European Parliament, the think tank of the U.S. Congress estimates that in 2014 the world will need 200,000 tons of rare earth metals, in 20-30 years may run out of raw materials necessary for the production of gadgets and media (or even faster - if their popularity will grow even more).

The solution to this issue can, and perhaps must, be recycling and disposal of materials already used. This means that the irreversible destruction of them in the course of thermal methods of data destruction harms not only ecological, but also the future development of technology - or at least maintain the status quo. The only method of destroying data, providing not only the irreversible destruction of data, but also the ability to recover valuable elements technology is LiquiDATA: destroyed for its help carriers move in the liquid, with which you can recover the elements to which these vehicles were built.
