摘要

In the realm of digital media, the proliferation of deepfake technology has brought forth significant concerns regarding its potential for misuse, particularly in areas such as political disinformation and privacy infringement. To counter these threats, we propose a groundbreaking approach to deepfake analysis that encompasses both image and audio detection. This method integrates advanced techniques such as Res-Next CNN for precise frame-level feature extraction from images and MFCC feature extraction for audio, coupled with LSTM-based RNN for comprehensive temporal analysis across both modalities. This model exhibits a remarkable ability to accurately discern between authentic content and deepfakes in both images and audio recordings. Additionally, our methodology emphasizes adaptability and scalability, ensuring its effectiveness across various digital platforms and evolving deepfake techniques in both visual and auditory domains. By continuously refining our model with ongoing advancements in AI and deep learning, we remain steadfast in our commitment to staying ahead of emerging threats posed by malicious actors. In addition to its utility in detecting deepfakes across multiple modalities, our system features a user-friendly interface for swift mitigation of AI-generated manipulations. A key feature of our system is the use of probability scores to indicate the confidence level of the classification. The resultant probability score obtained for various input data ranged between 50% and 90%. This probabilistic approach provides a nuanced measure of the system's confidence in its predictions, offering more detailed insights compared to the binary accuracy metrics commonly used in other studies. By leveraging the power of AI to combat AI, our methodology prioritizes simplicity and reliability, validated through rigorous evaluations on diverse datasets encompassing both image and audio samples.
