CHA Technology & Digital Tools 3

Question 1

Which of the following best describes the role of Automated Handwriting Analysis (AHA) software in a CHA's workflow?

Accepted Answer

It serves as a screening or decision-support tool, with the examiner making the final determination

Answer

AHA software assists by quantifying features and flagging similarities or differences, but professional standards require a qualified examiner to render the final opinion.

Question 2

A CHA is asked to analyze a handwriting sample submitted as a JPEG photograph taken with a smartphone. What is the primary limitation of this submission?

Accepted Answer

Camera lens distortion and lossy compression may alter proportions and fine stroke details

Answer

JPEG compression is lossy and camera perspective can introduce distortion, both of which compromise the accuracy of measurements and comparisons.

Question 3

In the context of digital tools for handwriting analysis, what is 'feature extraction'?

Accepted Answer

The automated identification and measurement of specific handwriting characteristics such as slant angle, loop size, and stroke width

Answer

Feature extraction uses algorithms to quantify measurable handwriting attributes, enabling statistical comparison between known and questioned samples.

Question 4

Which technology is most associated with detecting erasures or chemical alterations on a physical document?

Accepted Answer

Infrared luminescence examination using a VSC or forensic light source

Answer

Infrared luminescence can reveal chemical erasures, overwriting, and ink differences that are invisible under normal white light.

Question 5

A CHA using spectrographic analysis of ink can determine all of the following EXCEPT:

Accepted Answer

The identity of the specific individual who held the pen

Answer

Ink analysis reveals chemical composition and comparative information about the ink itself, but cannot identify who physically held the pen.
