Signature dynamics on a mobile electronic signature platform
This article is focused on signature dynamics that is used for protection of qualified electronic signature functions and personal data on mobile platforms. The article presents a concept of the Trusted Pocket Signer (trustworthy PDA with integrated SmartCard used as Secure Signature Creation Device (SSCD)), role of biometrics within this concept, and major handwritten signature algorithm strategies. The handwritten signature algorithm was tested on a large signature database that has been created. The structure of the database reflects various forging techniques and different quality of forgeries. This article also includes technical issues considering integration of biometric functions into the embedded Trusted Pocket Signer software.
