Since the use of AI has increased, it has become more dangerous than anything else nowadays. Leveraging the potential of this Artificial Intelligence, the deepfakes are generated by superimposing faces on one another, and even in audio also. To give solution to this problem, we present our solution, "Sach-AI", which gives the opportunity for deepfake detection in video, image and audio format. Moreover, the algorithms used in this research framework are very accurate and the best of all. Our system also proposed the methodology of implementing Blockchain in this framework where the location of the deepfake video producer could also be traced in realtime, even after the video is viral and reshared lakhs of times. We believe this solution will bring a ground-breaking impact in the field of deepfake detection and will protect the national integrity, thereby safeguarding the citizens.
