“Of course they're fake videos, everyone can see they're not real. All the same, they really did say those things, didn't they?” These are the words of Vivienne Rook, the fictional politician played by Emma Thompson in the brilliant dystopian BBC TV drama Years and Years. The episode in question, set in 2027, tackles the subject of “deepfakes” - videos in which a living person's face and voice are digitally manipulated to say anything the programmer wants.
Rook perfectly sums up the problem with these videos - even if you know they are fake, they leave a lingering impression. And her words are all the more compelling because deepfakes are real and among us already. Last year, several deepfake porn videos emerged online, appearing to show celebrities such as Emma Watson, Gal Gadot and Taylor Swift in explicit situations.
[...]
In some cases, the deepfakes are almost indistinguishable from the real thing - which is particularly worrying for politicians and other people in the public eye. Videos that may initially have been created for laughs could easily be misinterpreted by viewers. Earlier this year, for example, a digitally altered video appeared to show Nancy Pelosi, the speaker of the US House of Representatives, slurring drunkenly through a speech. The video was widely shared on Facebook and YouTube, before being tweeted by President Donald Trump with the caption: “PELOSI STAMMERS THROUGH NEWS CONFERENCE”. The video was debunked, but not before it had been viewed millions of times. Trump has still not deleted the tweet, which has been retweeted over 30,000 times.
The current approach of social media companies is to filter out and reduce the distribution of deepfake videos, rather than outright removing them - unless they are pornographic. This can result in victims suffering severe reputational damage, not to mention ongoing humiliation and ridicule from viewers. “Deepfakes are one of the most alarming trends I have witnessed as a Congresswoman to date,” said US Congresswoman Yvette Clarke in a recent article for Quartz. “If the American public can be made to believe and trust altered videos of presidential candidates, our democracy is in grave danger. We need to work together to stop deepfakes from becoming the defining feature of the 2020 elections.”
Of course, it's not just democracy that is at risk, but also the economy, the legal system and even individuals themselves. Clarke warns that, if deepfake technology continues to evolve without a check, video evidence could lose its credibility during trials. It is not hard to imagine it being used by disgruntled ex-lovers, employees and random people on the internet to exact revenge and ruin people's reputations. The software for creating these videos is already widely available.

1. Introduction

Fires are the accidents which occur most frequently, whose causes are the most diverse and which require intervention methods and techniques adapted to the conditions and needs of each incident. Depending on the type of fire (nature of the material ablaze), meteorological conditions (wind) and the effectiveness of the intervention, material damage can be limited (a single car, building or production or storage warehouse installation), or affect wide areas (forest or agricultural fires, hydrocarbons, gas or other highly flammable products, storage or piping installations, harbour installations and rail or marine transport equipment). […]

2. Preventive and protective measures

Fires can spread more or less rapidly depending on their causes, the nature of the material and goods alight, the fire prevention installations (automatic sprinklers), meteorological conditions, the ways the population is informed and the initiative it shows, as well as the speed and efficiency of the intervening services and of their fire-fighting equipment. In the light of experience, prevention is seen to be most important and consists of two distinct components. On the one hand, the primary responsibility falling upon the political authorities empowered to implement the legal prescriptions concerning fire protection, to forecast accidents and to inform the population, as well as to set up measures and means for fighting fires and explosions. On the other hand, the responsible behaviour of each individual based upon an education geared towards caution and the respect of instructions in case of fire. Defining, and controlling the implementation of, the particular rules of protection against fires, specific to each enterprise presenting a potential danger, including the training of security personnel, is also relevant in this context. The many types of fire and the preventive and protective measures which relate to them, make it advisable to limit the present study to the specific measures falling to the political authorities in one area only, namely that of “forest fires”. This type of fire is of particular interest to developing countries and the preventive measures to be applied have a general representative value, that is:

– organising an observation service, prevention and alarm (security) service at local and regional levels;

– implementing legislation regulating the use of fire by all the population present in or at the edge of forests, and more particularly by owners and individuals exercising a professional activity in sensitive areas;

– planning and concrete preparation (periodic maintenance) for fire-fighting through adequate landscaping of the territory and appropriate forest cultivation limiting fire propagation (alternating vegetation, clearance, trimming), creating and maintaining access paths (extinction) and fire-break areas as well as fire-fighting equipment such as water supplies (conduits, cisterns), watch towers and meteorological posts, and the construction of helicopter landing pads;

– surveillance and detection of fires as soon as the danger of fires is forecast by the ad hoc meteorological service (which comprises automatic or mobile statistics posts observing the winds and the vegetation: dryness, force, direction, evolution);

– as soon as the danger of fire increases, activating an alarm plan (basic intervention plan) requiring the engagement of preventive intervention squads (firemen), and their wide positioning as near as possible to the threatened zones, and making available water bombers and specialised aerial machines ready for action;

– preparation and concretisation (organisation) of an intervention mechanism: this requires the setting up of specialised management programmes ensuring the coordination of powerful and efficient equipment and means for fighting forest fires (instruction); 

– preparedness management and the coordination of the use of the means of intervention of the authorities and the information and alarm services for the population require a secure transmission network (radio network);

– planning the evacuation of the population possibly under threat in the various sensitive areas, particularly if there are risks of explosion (reservoirs and gas conduits explosives or ammunition dumps, hydrocarbon production, handling or transport installations, other dangerous material, etc.).
