ANÁLISIS FORENSE DE FIRMAS CAPTURADAS DIGITALMENTE


20/03/2021

Campus Forense organiza y certifica el primer curso de Análisis Forense de Firmas Capturadas Digitalmente con Nikolaos Kalantzis (Grecia).
Exclusivo para expertos de Latinoamérica y España.
Formación de primer nivel.

ANÁLISIS FORENSE DE FIRMAS CAPTURADAS DIGITALMENTE

Las firmas manuscritas siguen empleándose en nuestra vida diaria, ya sea para el registro de transacciones comerciales como para actos cotidianos. En los últimos años, la digitalización de numerosos procedimientos administrativos y comerciales ha ampliado la vida y uso de la firma manuscrita, ya no en un registro en papel sino en un formato digital. Así, es habitual que nos encontremos firmando en pads digitales con nuestro dedo o con bolígrafos especiales.

Con estos nuevos formatos aparecen nuevos problemas periciales que necesitan de profesionales capacitados y entrenados específicamente en este campo de trabajo emergente. ¿Es lo mismo peritar firmas manuscritas en tinta y papel que firmas capturadas digitalmente?, ¿se pueden cotejar unas con otras?, ¿se pueden cotejar firmas capturadas digitalmente con diferentes software y hardware?, ¿cómo se puede normalizar y cotejar información biométrica de firmas capturadas digitalmente con diferentes software y hardware?, ¿qué es una firma digital original? Estas son algunas de las preguntas que nos hacemos los peritos ante el nuevo desafío forense que involucran las firmas capturadas digitalmente.

Uno de los objetivos de este curso es formar los primeros expertos con competencias forenses para el análisis de firmas capturadas digitalmente. Otro, que estos expertos puedan brindar asesoramiento a empresas y organismos gubernamentales en la adquisición de software y hardware con la sensibilidad y robustez suficiente para minimizar la posibilidad del fraude documental con estas nuevas herramientas digitales



ENFHEX BEST PRACTICE MANUAL Version 3


18/01/2021

We are very happy to announce the publication of the 3rd version of the Best Practice Manual for the Forensic Examination of Handwriting of the European Network of Forensic Handwriting Experts (ENFHEX) – a part of the European Network of Forensic Science Institutes (ENFSI).

Mr. Niko Kalantzis, as a member of the Steering Committee of ENFHEX as well as a member of the STEFA Group 8 responsible for Appendix no. 5, contributed actively to the review and writing of this document.

The 3rd version of the BPM includes Appendix no. 5 which deals with the determination of authenticity of Biometric Signatures (eSignatures, Digitally Captured Signatures), which constitutes the first presentation of an analytical methodology for these new types of signatures.

The 3rd version of the Best Practice Manual for the Forensic Examination of Handwriting is an official document & can be freely downloaded here:

Α discussion on eSignature technology & its application


16/03/2021

A short video introducing the eSignatures (a.k.a. biometric signatures or Digitally Captured Signatures) & their importance. This video focuses more on the similarities of eSignatures to traditional pen & paper signatures from the aspects of usability, legality & safety.

Wacom Connected Ink 2020: From liquid to digital ink Lecture Now Available

The presentation of the manager & lead examiner of our Institute entitled “From liquid to Digital ink” that was presentaed at Wacom’s Connected Ink 2020 Event is now available:

Niko Kalantzis

Chartoularios Institute, Greece

From liquid to digital ink

A handwritten signature is more than just a name – it’s your unique sign of commitment, intent, and integrity. As a method of authentication, handwritten signatures are accepted around the world and even have an established legal framework and forensic methodology to investigate and determine their authenticity.

Can this experience and expertise be transferred from pen and paper to a digital biometric format? And if so, what is the path towards achieving equality between the two?

Join eSignature expert Nikolaos “Niko” Kalantzis as he explores:

  • The traditional handwritten signature as a means of authentication
  • The methodology of authenticating a signature
  • The definition of a digital biometric signature and the characteristics that are captured and encoded
  • Introduction to Digitally Captured Signature (DSC) technology
  • How traditional and digital biometric signatures can be compared
  • Usage and incorporation of Digitally Captured Signature (DCS) technology within the field of forensic examination
  • The current state of forgery of Digitally Captured Signatures (DCS): progress & challenges


New Publication: Digitally Captured Signatures (Biometric Signatures) & Forensic Handwriting Examination. A short Introduction

New Publication: Digitally Captured Signatures (Biometric Signatures) & Forensic Handwriting Examination. A short Introduction

New publication from our Institute’s Manager mr. Niko Kalantzis, in collaboration with Dr. A. Platt from Staffordshire University.

The article entitled “Digitally Captured Signatures (Biometric Signatures) & Forensic Handwriting Examination. A short Introduction ” was published in the 10/2020 issue of the Journal “Penal Justice / Ποινική Δικαιοσύνη”.

Abstract:

Digitally Captured Signatures are being established as a means of authenticating transactions and are gradually replacing traditional ones in transactions both within Greece and internationally. Still, the ease of the transition does not necessarily guarantee the suitability of the new medium. In this article we present the actual form of Digitally Captured Signatures and we present the analysis capabilities they provide to the Handwriting Expert.

Presentation for the 78th ASQDE Conference – The question of comparability of Digitally Captured Signatures


2/12/2020

Niko Kalantzis: Presentation for the ASQDE 78th Conference (August 2020)

As presented for the 78th conference of the American Society of Questioned Document Examiners (ASQDE)

The question of comparability of Digitally Captured Signatures

Description: When it comes to signatures, the shift from pen & paper to digital media is attainable but not trivial. In the physical world, different writing instruments of the same class form the executed signature in the same manner, but this cannot be said for DCS when captured with different software & hardware solutions (or even using the same hardware but different software only). This study discusses two aspects of this problem. The first part of the study involves the comparison of 1.200 samples created with an XY-plotter (Axidraw v.3), which were collected from 6 identical digitizer pads (Wacom STU-530) and the same software suite (Namirial FirmaCertaForensic) with different combination of the 6 default styli provided with the pads and 4 inking pens (Wacom Bamboo Spark). The comparison of the collected data from the same repeatable stimulus discusses the repeatability and the accuracy of the recorded stimuli from the Wacom STU-530 digitizer. The second part involved the analysis of the extracted (unnormalized) CSV data from different Software and Hardware solutions and the construction of a normalizing procedure for those to be accurately analyzed under the same DCS software analysis suite. Through the analysis of the actual method of recording the biometric channels (X, Y, F and T), the construction of a translation spreadsheet allows the accurate rearrangement of the collected data so that they can be read and analyzed in the ISO 19794-7:2014 compliant csv format of Namirial’s FIrmaCertaForensic DCS signature analysis software.
