The use of fractal analysis is recommended to place handwriting analysis within the purview of science and scientific methods. The current practice of subjecting a questioned document to a handwriting expert’s eye borders on art and is replete with subjectivity. A similarity index based on the fractal dimension of a handwritten document is proposed to augment the current practice. A random sample of ten(10) respondents, five(5) male and five(5) female, were asked to copy ten(10) paragraphs of the same lengths by hand. The first paragraphs for each respondent was used as the specimen document while the remaining nine (9) paragraphs were utilized to test and validate the proposed fractal procedure. Results revealed that the similarity index identified authorship as well as genuineness (of signatures) with 99% accuracy
