In 2004 Chinese researchers present a new approach to study the hand lines for biometric purposes. They applied a mathematical model on hand prints and were able to identify six types of palmar crease variations - based on the core characteristics of the three ‘major palmar lines’. Recently, in line with the Chinese research a new more advanced (PIC) model was introduced which e.g. describes 21 types of major hand line variations which are displayed in ’a family tree of the major hand line types’: see the picture above.
Interestingly, the new study reports e.g. about a correlation between the palmar lines and intelligence (IQ): left hand vs. right hand asymmetries appear to be involved, plus a lower prevalence of MPA’s – such as the simian line & Sydney line).
More details are available in the article:
What can formations in hand lines reveal?
For more information about various aspects of the palmar lines the following book is recommended:
‘Anthropology of Crease Morphogenesis’.
NOTICE: The three major palmar lines concern:
- The ‘radial longitudinal crease’, in palmistry a.k.a. the ‘life line’;
- The ‘distal transversal crease’, in palmistry a.k.a. the ‘heart line’;
- The ‘proximal transveral crease’, in palmistry a.k.a. the ‘head line’.

The IBMBS presents the 4th biometrics conference in 2009!
Jean-François Mainguet presents on his website an overview of 20 types of biometrics. The following 5 aspects of the hand play a significant role in modern biometrics:
Some additional aspects of the hand (and the use of the hand) that relate to biometric research are: handwriting, hand tapping, knuckle creases, hand pressure profile, finger wrinkles, and 3D finger surface.
The following 2 sources present some info about upcomming biometric events:
