Jan 1, 2014 · In dactyloscopy, the transfer of the pattern from the fingerprint ridges to the fingermark is accompanied by two types of loss of information: quantitative, due to the limited size of the trace, and qualitative, due to distortion, blurring, bad resolution, and loss of pore and edge details.

May 1, 2023 · The chemical composition of the fingermarks quantitatively varies between donors which can help to differentiate individuals. • The fingermark chemical composition can help differentiating individuals with an accuracy between 80% and 96%.
Jun 16, 2021 · Three main outcomes derived from the chemistry of fingermarks can be identified (Fig. 1.3): (1) improving the detection capabilities, (2) estimating the age of a fingermark, and (3) providing information about the donor, aka donor profiling. The detection of fingermarks has been carried out for more than a century; age estimation and donor ...

Mar 1, 2019 · Introduction. The establishment of a link between a questioned fingermark and an individual is a process that usually encompasses the application of a detection technique, the recording of the detected fingermark, and a minute comparison of the fingermark morphological characteristics with reference material (i.e., fingerprints) [1].
