Participants expressed opinions on the authorship of questioned signatures. We hypothesized that the duration-amplitude coefficients for forged signatures would be significantly greater than for genuine signatures suggesting non-adherence to the isochrony principle.

Calligraphers formed part of the population of individuals who provided simulated signatures for the trial. All signatures, known and simulated, were simultaneously captured both statically and dynamically.

Journal of Forensic Sciences47, Twenty-four types of paper brands were purchased from local market in and around Chandigarh, India. Sixty subjects 3 equal groups of 3 signature styles each provided 10 naturally written genuine signatures. Changes with condition for the other parameters were similar for the three styles. International Journal of Speech Language and the Law1 2pp.

Aunque la concordancia no es lo suficiente, causa problemas a la hora de discriminar la escritura de cada uno de los gemelos. Forensic Science International1pp. Australian Journal of Forensic Sciences48 6pp. Furthermore, the visualised representation of the non-visible, intra-signature segments illustrated an overall gross pictorial disparity between the known and simulated signatures, which may be of use during first pass authenticity examinations.

ABSTRACT The comparison of questioned and standard line traces in forensic handwriting examination has to date been based almost entirely on subjective techniques.

Documentología forense by Ernesto Meza on Prezi

ABSTRACT The aims of this study were to determine if computer-measured dynamic features duration, size, velocity, jerk, and pen pressure differ between genuine and simulated signatures. Es frecuente el uso del lapicero en notas de trabajo o documentos informales.

This proposition was tested in a signature blind trial that was administered to 42 forensic handwriting examiners FHEs. The program provides a series of measurement tools.

It is unlikely however that the majority of these subjective steps will be excluded. Writer style characteristics might therefore docuumentologia to be taken into consideration as potentially significant when evaluating signature fornse with a view to forming opinions regarding authenticity.

The use of forensee or certificate papers did not seem to influence in the inks distribution nor determining the order of the inks.

Ninety writers provided 10 genuine signatures, five disguised signatures, and five auto-simulated signatures. Journal of Forensic Sciences51 6 Although this study provided useful insights regarding crossing ink lines, future statistic studies may be helpful for more objective examinations. Emli-Mari Nel, Johan A.

Twenty-nine thousand eight hundred and eleven authorship opinions were expressed by FHEs on trial kits comprising randomized questioned genuine signatures written by the specimen writerdisguised signatures written by the specimen writer and simulated signatures not written by the specimen writer.

Although the prevalence of EPS has decreased due to the newer antipsychotics, EPS continue to limit the effectiveness of these medicines.


This leads to the FDEs expressing a smaller percentage of misleading responses when calling writings as either naturally written or disguised 4.


Milena Pugnaloni, Roberto Federiconi. Slope coefficients derived from simple regression models of the relationship between stroke duration and amplitude served as our measure of isochrony.

Data were captured and analyzed using MovAlyzeR software. It poses the question, are there lessons to be learned from the Australian experience that would have relevance to other parts of the world? Las similitudes en la escritura forese frecuentemente entre gemelos. All signatures were digitized to enable high precision dynamic analyses of stroke kinematics.

Participants performed a min handwriting task consisting of loops of various sizes and a sentence. Given the body of evidence supporting the potentially serious implications of domain irrelevant information, it was decided to introduce a context management scheme at the Document Examination Unit of the Firense Police Forensic Services Department.


With the introduction of computer aided examinations, more information should become available to the examiner on which to base subjective decisions. An analysis of eye movement search patterns by the subjects indicated that a very similar search strategy was employed by both groups, suggesting that visual inspection of signatures is mediated by a bottom up search strategy.
