PenMatrix Software can identify people by their handwriting
10 July 2013
German software vendor Paragon Software Group has unveiled PenMetrics, which it claims can measure a wide range of individual handwriting characteristics and parameters.
The parameters it measures include letter width, height, and inclination. These, and more, can be subjected to further analysis for a range of purposes, including determining whether or not a particular individual wrote a piece of text.
PenMetrics is capable of processing both plain text (scanned from a paper handwriting sample, for example) and dynamic text which could be collected using a range of mobile devices or graphics tablets.
Paragon said that, while handwriting is taught to children from an early age, personal style continues to develop over the years to add individual, defining strokes.
The company is now making the technology available to any organisation involved in handwritten analysis, including clinics, research labs, forensic or criminal analysts, profilers of missing or dead persons, law enforcement agencies, and other organisations.
Although PenMetrics is a new product, prior to bringing it to the market, Paragon Software has built it on experience gained while developing its proprietary PenReader handwriting recognition software which first appeared in 1997 for personal digital assistant (PDA) devices. Over the following years, specialised operations such as orthographical correction of recognition results and support for more than 30 world languages were added to the PenReader engine.
