Forensic Investigation Of Ai-Generated Synthetic Media Crimes
I. Introduction: AI-Generated Synthetic Media Crimes
1. Definition
AI-generated synthetic media refers to digital content—images, videos, audio, or text—produced or manipulated using artificial intelligence or deep learning techniques. Crimes involving this type of media include:
Deepfake pornography: Non-consenting individuals’ images or videos are manipulated to depict sexual acts.
Political deepfakes: Fake videos or audio created to influence public opinion or elections.
Fraud and identity theft: Using synthetic media to impersonate individuals for financial gain.
Cyber harassment or extortion: Threatening to release AI-generated content to intimidate victims.
Misinformation campaigns: Fabricating news or events using realistic synthetic media.
2. Forensic Challenges
Difficulty distinguishing AI-generated content from authentic media.
Rapid evolution of AI tools.
Detection requires digital forensics, machine learning analysis, and metadata tracing.
Evidence collection must ensure integrity for legal proceedings.
3. Applicable Laws
U.S. Law: State-level deepfake statutes, federal wire fraud, identity theft, and harassment laws.
UK Law: Fraud Act 2006, Communications Act 2003, Malicious Communications Act 1988.
Indian Law: IT Act 2000 (Sec 66D, 66E), Indian Penal Code (sections on defamation, cheating, and sexual harassment).
International frameworks: Emerging guidelines on AI misuse and digital content forensics.
