Synthetic media refers to any media content, such as images, video, audio, or text, that is partially or fully generated by artificial intelligence algorithms rather than being captured or created by humans. The goal is to produce realistic and convincing media that mimics authentic content.
Types of Synthetic Media
Deepfakes: Fake videos created using deep learning to swap faces, manipulate expressions, or generate entirely synthetic videos that closely resemble real ones. Deepfakes pose risks of spreading disinformation, manipulating public opinion, committing fraud, or blackmail.
Synthetic text: AI-generated text, such as poetry, created by neural networks trained on large datasets. Applications include content creation and information storage in synthetic macromolecules.
Synthetic speech: Text-to-speech systems that generate human-like synthetic voices for applications like dubbing, announcing, and narration. Deep learning has made these systems more accurate and accessible.
Synthetic drugs: While not media per se, synthetic drugs are an emerging concern, with a reported shift from natural to synthetic drug consumption.
Key Characteristics of Synthetic Media
Artificially Generated: Synthetic media refers to content like images, videos, audio, or text that is partially or fully generated by artificial intelligence (AI) and machine learning algorithms, rather than being captured or created by humans.
Mimics Real Content: The goal of synthetic media is to produce realistic and convincing content that closely mimics authentic media created by humans. Advanced AI models are trained on large datasets of real media to learn to generate highly realistic synthetic versions.
Spans Multiple Formats: Synthetic media technologies can generate various types of media formats including images, videos, audio recordings, written text, and more.
Blends Real and Artificial: In addition to fully synthetic content, there is also semi-synthetic media which blends real captured media with AI-generated elements. For example, inserting an AI character into a real video.
Customizable Composition: For some applications like biomedical research, synthetic media can be generated with customized compositions tailored for specific needs, such as varying nutrient levels or additives in synthetic growth media for cultivating microorganisms.
Potential for Misuse: While synthetic media has creative and research applications, it also raises concerns about the potential for spreading misinformation, deception, and misuse if the artificial nature is not properly disclosed.
Requires Authentication: As synthetic media becomes more advanced and difficult to distinguish from real media, developing techniques to authenticate the origin and integrity of media content is an important challenge.
