Webcam hacking just as easy as googling it

Did you know that it is possible to access cameras through Google? A special program is not needed even needed for badly secured webcams. Hermans from Metronews did some research on this. He searched ‘Intitle:”Live View / -AXIS’ and within no-time he found himself at the university in Heidelberg, a camera shop, and even in some kind of kitchen. The latter camera was even controllable. Again, all of this need not any technical program. A simple search on Google was enough (Herman, 2017).

The extraordinary capabilities and value added due to the digital revolution has also taken a toll on our privacy. The simplicity of hacking a webcam raises the awareness of how easy individuals can be viewed without consent. We accept (and even value security) cameras at public places because it is in our own interest to feel safe and to know that in case something happened the situation has been filmed. However, footage from hacked webcams could be used against individuals, even if these cameras are from public places. People who were not supposed to be somewhere can easily be found through hacked security cameras, resulting in blackmail or other types of extortion. In extreme cases as with sextortion (type of blackmail that in which sexual images or videos are used) individuals’ personal lives can unimaginably change for the worse.

While writing this article at the university, I found myself looking around for security cameras, wondering if somebody could see me through his/her computer screen. I thought that if people were indeed looking at me, it would not matter because they would not have anything to hold against me because I am behaving normally. But then I thought, this way of thinking is catastrophic. There are more cameras than people at this university; every computer camera could be hacked, and every person has at least three cameras carrying around (two on every smartphone, one on every laptop). The sticker on my laptop camera covers nothing since the 300 other cameras in the same room can easily record me too.

Though we all know that we are constantly being viewed and monitored by public security cameras and our devices, the real danger lies in our ignorance of the consequences. In developing new technologies and governance, we must recognise that the possibility of being viewed without consent (even though individuals do not mind), endangers our unconscious freedom of movement.

One Bitcoin transaction costs more power than my entire household of three for a month

Along with the rise of The Bitcoin comes the rise of power consumption. At the same time, the environment is desperately in need of less of it.

One Bitcoin transaction consumes on average 200 kWh of electricity. I can easily run 400 washing cycles with 200 kWh. In fact, it is enough to run my entire household of three people for a month.

The image above shows a world map of countries that currently consume less power than global Bitcoin mining. According to Digiconomist, Bitcoin mining consumes 33 TWh every year, which is about the same as Denmark. More disturbingly, at a power consumption growth rate of 25%, Bitcoin alone will consume as much electricity as The US by 2019, and even as much as the entire world now by 2020.

The big question now is: will the world be able to supply the staggering demand of power sustainably? This issue is rather challenging. Bitcoin does not stand alone when it comes to increasing power demand; the very heart of our modern economy is based on the digital world and therefore relies heavily on power generation to run the data centers.

Bitcoins power usage is mostly generated by coal-fired power plants. The consequences of burning and mining coal include land use, waste management, and water and air pollution, which cause severe health issues. Despite those concerning consequences, people and governments are reluctant to give up the use of coal as an energy source because of its abundance and cheap rate.

The power consumption of Bitcoin is a challenging, yet necessary opportunity for the power industry to develop sustainable and clean power generation, and fast. Currently, the power industry is by no means able to match demands with sustainable energy. If the world cannot find a way to produce sustainable and clean energy fast, we will find ourself burning coal for the next generations to come.
