How We Detect Counterfeits
Advanced AI technology for secure currency verification.
Our system uses contrastive learning (SimCLR) to create meaningful embeddings of banknotes. This allows us to compare new notes against a database of verified genuine notes.
The model analyzes visual features like security threads, watermarks, and microprinting to calculate a similarity score between the uploaded note and genuine samples.
We maintain an extensive database of genuine Naira notes (₦200, ₦500, ₦1000) from various print batches to account for normal variations in legitimate currency.
Notes that fall outside the expected similarity range for genuine currency are flagged as potentially counterfeit, with visual explanations highlighting suspicious features.
