With reference to deepfake technology, consider the following statements:

1. Deepfake technology employs Generative Adversarial Networks (GANs) to generate synthetic media by training a generator model to create fake content that is indistinguishable from real content, while a discriminator model evaluates its authenticity.

2. The detection of deepfakes relies solely on traditional forensic techniques, such as analysing pixel-level inconsistencies and examining metadata associated with the media files.

3. Deepfake applications extend beyond malicious uses; they can also be utilized in legitimate fields such as entertainment, education, and virtual reality for enhancing user experiences.

4. Recent advancements in deepfake generation techniques have led to the development of tools that can create high-fidelity audio deepfakes, making it challenging to discern between genuine and manipulated audio content.

Which of the statements given above are correct?
