ABSTRACT
Determining the age of latent fingerprint traces found at crime scenes is an unresolved research challenge since decades. In prior work, we have suggested to use optical, non-invasive image sensory in combination with a new aging feature called binary pixel (shown to have a characteristic logarithmic aging tendency on an ideal hard disk platter surface) to solve this important research issue. In this paper, we want to evaluate the feasibility of this approach for a practical age determination by conducting 30 test series with a total of 1440 scans, investigating ten different surfaces with 3 different samples each. We suggest a three-step procedure: calculate the binary pixel feature, approximate the mathematical aging function using regression and calculate the coefficients of correlation, allowing for a formal evaluation and comparison of the aging property. We report a promising characteristic logarithmic aging property for 18 of the 30 test samples and evaluate possible influences on such property.

Approximation of a mathematical aging function for latent fingerprint traces based on first experiments using a chromatic white light (CWL) sensor and the binary pixel aging feature
CMS'11: Proceedings of the 12th IFIP TC 6/TC 11 international conference on Communications and multimedia securityThe age determination of latent fingerprint traces is a very important challenge for forensic investigations, which has not been solved satisfyingly so far. Based on prior work, we use the novel and very promising aging feature of counting binary pixel ...

Anticipating ageing: Older adults reading their medical records
Highlights- Older adults, who are still active in working life but approaching retirement, differ from other age groups by their health information behaviour.
AbstractIn spite of the general interest in health information behaviour, there is little earlier research on how older adults, who are still active in working life but approaching retirement, differ from other age groups. A survey with ...
