There are different kinds of handwriting in this world; some write purely, and some make a fuss on the sheets. It is believed that handwriting is a special signature representing the personality of the writer. But can it tell the gender of the writer? This is an interesting question that has preoccupied forensic professionals and researchers over the years. To the students and the future practitioners of the field of forensic science and to those who are just inquisitive of the latent evidence of human handwriting, recent scientific research affirms some interesting facts about this subject.
What Forensic Science Says about Gender and Handwriting
Forensic handwriting examination is an expert science applied in criminal investigations, verification of document authenticity, and profiling. Historically, handwriting examiners consider personal characteristics, including the shapes of letters, slant, and spacing, pressure, and the size. These traits are individual, and they depend on motor skills, habits, and in some cases, gender related traits.
Research in science has evolved to adopt sophisticated technologies such as artificial intelligence (AI) and machine learning to identify subtle differences in handwriting which could be related to gender. Recent research, including the one in 2025 by a group of computer scientists and forensic experts, integrates deep learning models with handwriting characteristics to determine a writer based on his or her gender with remarkable accuracy.
The mechanism of handwriting gender prediction: How does it work?
In modern forensic studies many characteristics of handwriting are analyzed including:
- Letter shape and curvature
- Size and height of letters
- Digitally measured pressure on paper.
- Spacing and text inclination.
- Stroke smoothness and speed
These features are examined using machine learning models, namely convolutional neural networks (CNNs) such as ResNet18 architecture, which takes scanned handwritten documents as input. The system initially checks the integrity of the document through cryptographic hashing, which is vital in legal evidence and the gender of the writer, which with a controlled study is determined with over 90% accuracy.
This two-pronged method was proved in one study in 2025, where the evidence does not get lost, and the gender classification remains credible, a huge leap in the field of forensic science in a real crime-solving situation.
Why is this important?
The identification of the gender of the author of a handwritten note or a document as found at a crime scene can be used to reduce the number of suspects or locate victims, in cases where other identifiers are not available. Gender identification on the basis of handwriting is an additional profiling tool, helping the professionals of the forensic team and investigators learn more about the origin of the non-printing. This practice is especially useful in those instances when there is no digital or photographic evidence.
What Does The Research Say?
As recent studies indicate:
- Gender prediction using deep learning may achieve high accuracy of 97 on various datasets with handwritten specimens.
- The aspects of handwriting used vary statistically between males and females, which means that AI models can identify gender patterns in handwriting.
- A combination of machine learning and conventional forensic analysis will provide both increased accuracy and legality, as it will guarantee the authenticity of evidence.
- These models have been applied to different languages and scripts, including English, Arabic, Gurumukhi, and Sinhala, demonstrating that the method is very versatile.
Career in Forensic Science and Handwriting Analysis
To people interested in forensic science in India and other parts of the world, handwriting analysis is an important element of skills provided in the diploma and degree programs in conjunction with forensic psychology, DNA, and criminal law. By taking forensic science classes that incorporate document examination training, you have the knowledge to implement these modern AI techniques and traditional methods of handwriting analysis in the real world of investigation.
