To evaluate whether automated classification trees trained on freely available archival metadata can accurately detect forged artworks.
Compiled a comparative database comprising 1,704 authentic paintings and 210 documented fakes attributed to artist Félix Vallotton.
Extracted publicly accessible artwork attributes, including subject matter, dimensions, execution date, and signature details from auction records, sales receipts, and online descriptions.
Trained and evaluated a classification and regression tree (CART) model to distinguish between authentic artworks and counterfeits based on these features.
Specific multidimensional combinations of documented artwork attributes effectively separated authentic pieces from forgeries within the Vallotton collection.
Demonstrated that automated decision tree models utilizing standard public sales and catalog data provide a functional preventive screening tool against art counterfeiting without requiring laboratory-based physical analysis.
