Speaker – Tomlinson (Tom) Rauscher

Topic – Electronic Signatures – Capture, Storage, and Verification


The COVID-19 pandemic has accelerated the use of electronic documents and signatures. We describe various signature capture device types, and the range of information including signatures they can collect. Biometric signatures can be stored with documents in a secure way, so that the attempted modification of signed electronic documents after signing can be detected. Pitfalls of other signature types illustrate how documents can be presented to try to fool forensic document examiners. Summaries of court cases provide insight into the legality and utility of electronic signatures. We present software tools to support forensic analysis of electronic signatures by professional document examiners, focusing on signature verification. Armed with this information and these tools, forensic document examiners will have deeper insights into analyzing document and signatures, and can provide guidelines for designing secure signature capture systems.
