The present work reports the result of writer verification under different ink width conditions using chain code methods. It is observed that the style of a writer and writing instrument used, greatly affects the handwriting. The objective of this work is to improve the verification rate under different ink width conditions. In this work, the writer is verified using multistage approach. The writer is verified based on the writing slant at the first stage, the consistency in the writing style at the second stage, and the writing pressure at the third stage. If the writer is not verified correctly at all three stages, then only it is considered as misclassified. The authors tested the proposed multistage method on their own created dataset of 981 writers including two samples using ball pen and two samples using sketch pen. The experimental result shows that the false acceptance rate is 3.75 % on created dataset of 3924 samples. The proposed system improves accuracy with less computational complexity and verification time.
