Zanini* landmark Identification for reading of the digital ones or the Iris of the eyes, authentication for voice command and face are only some of the mechanisms already comumente seen in hollywoodianos films to guarantee the safe access to a system of data. This esteretipo is in the head of the people as a model of advanced and futurista protection. But the reality is more complex. What it is, after all, an excellent notice in a world where each time more given and documents are stored and distributed digitally. With the technological evolution, the security of the information from passwords and attribution of access levels left of being the form most efficient to keep a document.

To assure the maximum levels of protection in the electronic document transactions is one of the main concerns of the enterprise world. Great and average the company already had perceived that this is one of the priorities in the management of the technology. Now, with the adoption of certainly goes to heat the debate on the security of systems. The electronic note helps to reduce the costs of acquisition of paper, the costs of fiscal document storage, eliminates the time of stop of trucks in fiscal ranks of border, eliminates the digitao of forma bills of sale in the reception of merchandises, among others benefits. Everything this already is known. But the point that really worries the companies when we speak in the transaction of electronic the forma bill of sale is the security. This makes sensible? Yes. Total trustworthy resources of protection exist but the company needs to acquire knowledge itself of the necessity to use them. The NF-e is a document> inspector emitted and stored electronically, whose legal validity is guaranteed by the digital signature of the drawer. The document is signed digitally by one third trustworthy part, that associates an entity (person, process, server) to a public key.

The development of solar energy in 2007 shows a bright future, according to Greenpeace. The world market grew 40% and in 2015 will compete in some areas with traditional energy. Despite the lost time, nature sheds further light on what is the best alternative in the transition to a low emissions.

Renewables have covered most of the needs of man until the nineteenth century, when they were replaced by coal mining, and since 1950 by the “black gold.” While geopolitical threats increase the oil supply, prices rise and it reaches its end, it is becoming increasingly clear how this has influenced environmental barbarism. All studies have confirmed something: nature always comes. However, governments do not seem able to find a solution. For now, investment in research and development (R & D), both public and private, are not in line with the urgent needs of challenges to overcome. They have lost too much money and time to adapt traditional energy.

Experts have reiterated their concerns about biofuels as potential substitutes, both for the consequences this would have to feed millions of people and by the lowest performance against energy expenditure required for its production. That is why the EU is now rethinking the idea of covering up to 10% of transport fuel by 2020 with ethanol and biodiesel. And similarly, alternatives such as chambers for CO2 capture and storage suggest that we are going crazy. The difficulties in finding a safe method of disposal will be added groundwater pollution and other effects, a price tag too high.

In the passed month, in the city of Copenhagen (Denmark), it occurred the Cop15, Conference of the ONU on the Climatic Changes. The conclusion of that the great meeting did not get resulted forts was unanimous for diverse involved specialists who had folloied of close the negotiations. To only cite a case, the presidents of important nations as U.S.A. and Brazil, they had arrived no longer final of the round of debates. This delay allowed that many colloquies were not carried through seriously.

The result of Cop 15 sufficiently remembered the case of Kyoto, in which promises had been made that until had today not been fulfilled. In Copenhagen they want to impose impossible tasks. In this case nobody goes to sign the papelada one of quotas of emissions. The problem in general seems not alone to be of governing and authorities. We perceive in day-by-day as not yet we are involved in the ambient question. The Brazilian media exactly contributes for the lack of stimulaton to the support. We almost do not see notice on global heating and its consequncias in periodicals.

What to play outside, that is, we think that everything what we consume and does not have more use can be discarded not leaving no resqucio. The truth, however is another one and everything needs to have a final destination, in which it must be treated ecologically not to leave harmful vestiges in this way where we inhabit. The ecosystem as inexhaustible for the technologies has a urgent necessity not to treat more. The environment is not neutral for the linear economic system produce-consume-to discard, beyond that it is possible yes to have certain social improvements independent of the economic growth.>
