Introducing a formalism defining the B dl set and additionally also the L dl set serves
not just to correctly verify and identify the given person as shown in Figure 6.7, but
also to understand, as such, this image data.
Fig. 6.7. The process of verifying and identifying a person by their biometric analysis
The essence of the biometric analysis is the correct definition of a set of bio-
metric traits based on which a system database is built, which contains all the
biometric patterns defined in the system. The verification process consists in com-
paring selected data with the patterns stored in the system. On this basis, the sys-
tem determines whether the data corresponds to the pattern stored in the system or
is inconsistent with it. So as a result of the system operation, it is possible to de-
termine whether the analysed biometric data belongs to a given person or not. In
the identification process, it is possible to identify who the person whose biomet-
rics has been analysed is.
The combination of the biometric and semantic analyses makes it possible to
cognitively/semantically verify and identify persons. These aspects of cognitive
analysis complement identification processes by adding the functionality of se-
mantically interpreting the results obtained. This is why, in addition to the pre-
sented biometric analysis of the hand, the hand bone image is semantically ana-
lysed in parallel.
The semantic analysis of X-rays of hand bones is based on mechanisms of lin-
guistically perceiving and understanding data defined in the form of a formal
grammar. The key in introducing the right definition of the formal grammar is to
adopt names of bones found within the palm, which include the following:
