About

Copy-paste? Let’s look. Let’s analyze.

An increasing number of scientific publications are facing retraction requests due to suspected image manipulation, including potential copy-paste duplications in key figures—particularly in Western blots. In some cases, these suspicions point to scientific fraud.

Our platform is designed to bring transparency, rigor, and objectivity to the analysis of such disputed cases.

When suspicious areas are flagged in an image, they are often highlighted using colored rectangles—red, blue, green, or yellow—inserted by whistleblowers, reviewers, or investigative bodies. We use these visual annotations as the starting point for a deep comparative analysis.

Example
Specifically, our tool:
  • Automatically extracts image regions based on matching annotation colors.
  • Displays them side by side for direct visual comparison.
  • Displays an animation show the two images : the blue area gif .
  • Performs precise metric analyses (correlation, structural similarity, histogram comparisons, overlap analysis, etc.) to assess the degree of duplication.
  • Provides evidence-based insights to answer the question: Is this a copy-paste or not?

Our goal is to equip ethics committees, journals, researchers, and institutions with a reliable tool to objectively evaluate allegations of fraud and uphold the integrity of scientific publishing.

Look at the evidence. Analyze the data. Decide with clarity.
