Netanel Raviv, an assistant professor at Washington University in St. Louis, has led a team to develop a groundbreaking method for embedding unique fingerprints in 3D-printed objects. These embedded fingerprints can withstand tampering or breakage, providing crucial forensic information such as the identity of the printer, ownership details, and the time and location of printing.
The innovative research will be presented at the USENIX Security Symposium in August 2025. The team’s framework, Secure Information Embedding and Extraction (SIDE), utilizes robust mathematical techniques and security mechanisms to ensure the integrity of embedded codes in 3D-printed items, even in the face of adversarial attacks.
Raviv’s pioneering work in embedding secure information in 3D printing not only enhances forensic investigations but also raises the bar for protecting public safety against the misuse of this technology. The SIDE framework provides a formidable defense against malicious tampering, requiring a high level of expertise from potential adversaries to evade detection post-crime.
