Deepfakes are incredibly realistic manipulated videos that feature someone doing or saying something they haven’t actually done or said. They have been becoming increasingly popular in recent years, thanks to improvements in artificial intelligence (AI) technology and the internet’s vast reach. Deepfakes have been used in a variety of fields, from entertainment to politics, to defame and damage people’s reputation. They have become a significant concern for governments and policymakers as their misuse poses a threat to national security, legal systems, and democracy.
A deepfake is a combination of the words “deep learning” and “fake.” Deep learning is a machine learning technique that relies on artificial neural networks to learn complex patterns and behaviors from data. AI algorithms are fed with vast amounts of data, such as images, videos, and audio recordings, to train them to recognize specific patterns, and then make predictions based on those patterns. Deepfakes manipulate the output of these AI algorithms to generate synthetic media that looks and sounds almost identical to real-life media.
The deepfake technology is based on Generative Adversarial Networks (GANs). GANs consist of two AI-based neural networks, Generator and Discriminator, that work together to create deepfakes. The Generator uses a set of training data to create synthetic media, for example, a video showing a person’s face speaking words they have never spoken before. The Discriminator, on the other hand, is trained on a genuine set of data and can differentiate between natural and fake content. The Generator and Discriminator continuously train and learn from each other, ultimately creating more realistic deepfakes.
The easiest way to create a deepfake is to use an app or a software that can synthesize videos or audio recordings. The internet is full of free or low-cost software options that can be downloaded and used by anyone with basic computer skills. The process begins by selecting the video footage or audio recording to alter. It could be a celebrity, a politician, or a person of interest. Then, the software will instruct the user to upload samples of the person’s voice or face to learn their unique features, accent, or pronunciation. The software will then map these features onto the target video or audio clip, creating a new, synthetically generated media that closely resembles the original content.
Deepfakes carry significant risks as their malicious use can cause massive harm to individuals and communities. For example, criminals can use deepfakes to create a video of a person committing a crime as evidence in a court case, creating confusion among jurors and manipulating the course of justice. Politicians and public figures can be defamed and attacked through fake interviews or speeches designed to damage their reputation and undermine trust. Fake news generated through deepfakes can spread quickly on social media, creating confusion and mistrust among people and communities. Therefore, the widespread adoption of deepfakes poses a significant threat to the truth and the proper functioning of democracies.
Governments and policymakers are taking several measures to address the risks associated with the use of deepfakes. They are:
-
Regulating the development and use of deepfake technology: Several countries, including the US and China, have already passed legislation regulating deepfake technology. Such laws impose legal liabilities on those who create and disseminate malicious deepfakes. They act as a deterrent to people engaging in such activities.
-
Technology-based solutions: Several companies, like Microsoft, Google, and Facebook, are developing platforms that can detect and identify deepfakes. These platforms can identify the manipulation of facial features, audio glitches, and other signs of tampering. In addition, AI and machine learning-based solutions that can distinguish between real and fake content are being developed.
-
Raising awareness: Governments and policymakers are making efforts to educate people on the dangers of deepfakes. People need to know how to identify, analyze, and report fake content. Awareness campaigns are being organized to ensure that people understand the potential impact of deepfakes.
Deepfakes pose a significant threat to privacy, democracy, and national security. Their progress and impact must be monitored closely, and regulations must be formulated to ensure that they are used wisely and ethically. The development of technology-based solutions and awareness campaigns must continue to help prevent the spread of deepfakes. Therefore, it is essential to acknowledge the fact that deepfakes are a reality and face them head-on by formulating policies that ensure their ethical use.
