El cifrado de datos en la vida diaria de las personas


      El cifrado es el proceso de codificación de datos, de modo que solo alguien con la clave puede leerlos o acceder a ellos.

      07:46 – Vas a tu trabajo y el tren está lleno de gente, pero te las arreglas para tomar un asiento. Tomas un sorbo del café que compraste, con tu tarjeta, en el puesto del andén. Cuando usaste tu tarjeta de crédito, usaste tres puntos que involucran el cifrado: el chip de tu tarjeta, el lector de tarjetas y la transmisión de la información de la tarjeta para autorizar la compra.

      16:39 – Al final de tu día de trabajo, miras hacia abajo en tu rastreador de ejercicio y ves que has caminado 8.000 pasos. ¡Buen trabajo! Casi hace que el almuerzo valga la pena. Debido a que existe una comunicación segura entre tu rastreador y su aplicación, sabes que tu información de salud se mantendrá a salvo de cualquier persona que piratee el Wi-Fi público gratuito que usas en la estación de tren. Usas tu pase de prepago para acceder a la estación de tren para regresar a casa. Te acuerdas de que hace unos meses te molestaste cuando la autoridad de tránsito actualizó su sistema de pases, pero el nuevo sistema usa criptografía para ayudar a garantizar que nadie pueda pasar su tarjeta como si fuera tuya.

      18:00 – Vas a comprar la cena. Como no llevas efectivo, utilizas una aplicación de tu móvil para pagar. Cada vez que realizas un pago de esta manera, los datos de la transacción se protegen mediante cifrado.

      Tan pronto como llegues a casa, enciendes tu televisor inteligente para ver tu serie favorita. Debido a que tu Wi-Fi está cifrada, tu vecino que presume saber mucho de cine nunca se enterará de tus gustos.

Q2383502 Inglês
Text 3A4


      During the last century water infrastructure projects involving large dams played a major role in the socio-economic transformation of many countries. At the same time, in a significant number of cases the benefits were not shared equitably, and the negative impacts on the environmental and sociocultural structures were excessive. In some cases their economic performance was questionable. Diverging views have arisen on the merits and demerits of dams, the roles they play, and their alternatives in providing water and energy services. However, recognition that such roles are complementary rather than mutually exclusive has been growing as the dam debate has moved forward.

      It is envisaged that, as part of the global effort to improve water and energy supplies, more dams will be constructed, especially in developing countries, alongside other diverse alternatives. There will, consequently, be a need to enhance the benefits of dams and avoid many of their drawbacks by applying better decision-making processes within the overall framework of sustainability. There are complex issues around the planning and management of dams in the context of sustainable development which will need to be adequately considered and addressed to achieve sustainable outcomes.

      Dealing with the environmental and social challenges within the context of meeting water and energy needs is at the heart of the sustainability of projects involving dams. Dams are one of the options, structural or non-structural, available to meet specific water or energy needs. In many cases water and energy services are best provided through a mix of options. Each case is different. A decision to build a dam should emerge after a comprehensive assessment of the full range of available options, giving appropriate consideration to all aspects of sustainability.
