AI technologies are driving transformative changes across various industries, reshaping how we work, communicate, and live. From healthcare to finance, transportation to entertainment, AI is revolutionizing processes, enhancing efficiency, and unlocking new possibilities. Understanding the power and limitations of AI is crucial for setting realistic expectations and utilizing it efficiently across various tasks. Forensic document examination, like any other field, is not exempt from the need to understand where and how it can benefit from leveraging AI technology.

      Parascript, a leading developer of AI products specializing in pattern recognition, offers innovative solutions for handwriting analysis and fraud detection. In response to a growing interest from forensic experts, Parascript provides a presentation aimed at introducing forensic document examiners to the application of AI technology in their field. The presentation will delve into the fundamentals of AI technology, trace its evolution, and dispel common myths surrounding its capabilities.

Workshop

Alzheimer’s Disease and Handwriting –
What does the latest research tell us?
Carina Fernandes
Senior Handwriting and Document Examiner and Laboratory Manager at NC
Forensic Institute in Porto, Portugal.

Abstract

     With the aging of the population, forensic case work involving handwriting of the elderly, such as signatures written in wills or declarations, is becoming more and more frequent. The analysis of handwriting attributed to the elderly can sometimes pose special challenges for Forensic Handwriting Examiners (FHEs), since changes in handwriting due to illness and/or medication may be frequent. Although the influence of illness on writing has been extensively described in the literature, little attention has been given to handwriting changes due to neurological conditions, such as Alzheimer’s disease, especially regarding signatures and from a Forensic Handwriting Examiner’s perspective.

     In this context, this workshop will present the most recent developments regarding the effect of Alzheimer’s disease on handwriting, including the impact of this illness on static and dynamic features, based on the latest research using digitally captured signatures. In addition to having hands-on contact with handwriting samples produced by individuals with Alzheimer’s disease, participants can also bring their own cases for group discussion.

     If you have had a case or have a family member or friend with Alzheimer’s disease, and would like to share a writing sample for group discussion, please send it to the presenter ahead of the symposium (ncforenses@gmail.com).

Determining the Approximate Date of a Questioned Document Based on a Paper Fiber Comparison
Walter Rantanen and J. Michael Weldon

Abstract

     The case centered on an assertion by the Plaintiff, a recently terminated employee, that an undated document in his employee file was not in the file in the late 1990’s when his employment began, but was placed there in 2018. The file also contained other documents that were dated in the late 1990’s. Defendant, a Texas employer, asserted that the undated document was in the original file. The employer who had possession of the original file provided it for analysis.
     The papers were examined with Ultraviolet lighting techniques, removing paper samples, and applying paper chemistry analysis in the laboratory to establish the likely date of the document in question. Based on the testing, the paper fibers in the 1990 questioned document matched those of the other contemporaneous documents in the file. These paper fibers were different from the paper fibers in the later documents.

Line Quality and Alterations in Copied or Digitally Processed Documents
Tamara Kaiden and Robin Williams

Abstract

     This presentation will combine by example and description a variety of topics related to line quality in handwriting and printed text in copies and digitally processed documents that will include photocopies, scanned documents, and PDF documents that have been altered.
     The discussion will illustrate unusual backgrounds that are outside of the printed text and what the line quality in handwriting on PDF documents may indicate. An example of digital erasure marks on PDFs will be described followed by a demonstration of how digital erasing is accomplished using scanned documents.
     The presenters will discuss and demonstrate how the digital quality of two or more signatures on the same page of a document with a questioned signature may demonstrate evidence of electronically transferred signatures from different sources.
     Depending on the copier used to make multiple generations of copies of a document, an erroneous conclusion can be reached by a document examiner. The presenters will demonstrate the effects that specific printers have on line quality and demonstrate how specific copiers can create different outcomes when making generational copies of documents.

A Protocol for Examination of Anonymous Writing
Emily Will

Abstract

     While there are standards in the field of forensic document examination addressing topics such as “Examination of Handwritten Items,” “Examination of Typewritten Items,”  Examination of Documents for Alterations,”  “Terminology for the Expressing Conclusions of Forensic Document Examiners,”  there are no standards that expressly relate to Examination of Anonymous Writing.

     There are sufficient and significant differences in the examination of anonymous writing to warrant specific guidelines.  In this presentation a protocol is demonstrated, and the attendees will be encouraged to comment upon and add to this protocol.  Cases will be presented that clarify why this protocol is needed. when making generational copies of documents.

Disguised Writing – A Complex Case
Adele Thonn

Abstract

     Approximately 100 anonymous notes were distributed over the course of seven years in a small town in northern Louisiana. There were several suspects, some from the same family. Various letter forms often illustrated in texts on handwriting identification were used. To avoid detection, the writings were also written on varying substrates or surfaces. A meticulous analysis of each letter form on every anonymous note revealed the writer’s natural habits, resulting in an identification.

The Unmasking of The Masked Ball
Joseph G. Barabe

Abstract

     Two works of German Expressionists purchased by the client at the same time were of questioned authenticity. The first, a Self Portrait sketch, attributed to Lionel Feininger, was signed and dated 1919; the second, a signed but undated Masked Ball by Emil Nolde, possibly from his “unpainted paintings” period during WWII, during which he was forbidden to paint by the Nazi regime. Both were suspected to be forgeries, as both were acquired at very low cost from a gallery that failed shortly after the sale in 1978. The Feininger was found to contain anachronistic materials and was quickly concluded to be a forgery. The Nolde was more ambiguous; not only was it undated, but all of the materials identified were available during WWII, in 1978 and later. But there was something troubling about the signature. This presentation will discuss the process of uncovering the mystery of this signature and its implications for the possible authenticity – or lack thereof – of this painting.

Poster Session

An Adobe Photoshop Tool to Check for Electronic Alterations
Rima Askurava

Abstract

     One of the first steps a document examiner will want to take in examining for an altered or fabricated document is to obtain the electronic files of the originals or the best copies of the evidence.  Once the electronic files are received, the PDF can be imported into Adobe Photoshop and analyzed with a special function that separates the images from the text when the layers are still present in the electronic file.  The challenge is to determine whether the separated images are the result of the defects of the Optical Character Recognition software or are actual alterations of the document.

     This poster session will demonstrate both end results.
