Chemical analysis of fingermarks has shown potential to complement the image-based biometric identification processes. Various analytical techniques have been explored to analyse the chemical information contained within fingermark residues. Nevertheless, there is no systematic approach for integrating chemical analysis into the biometric recognition process. The position presented in this paper is that the integration of rich chemical information has the potential to complement biometric identification and provide additional investigative information. We highlight the role of ToF-SIMS as a high-resolution and non-destructive technique for chemical imaging of fingermarks in the forensic analysis. We propose strategies for automatic data analysis complemented with a proof-of-concept case study on the classification of fingermark contaminants. Finally, we outline a research path towards the integration of chemically augmented fingermark analysis into the biometric recognition process.
