The International Standard ISO/IEC 19794-7 specifies data interchange formats for online signature data in the form of multidimensional time series representing the signature dynamics. ISO/IEC 19794-7 specifies the following data formats for online signature time series data: a full format applicable in a wide range of application areas where handwritten online signatures or signs are involved, a compression format, a compact format, and an XML-based format. These formats support interoperability and data interchange among the subsystems of open online signature recognition systems.
