Signature Extraction and Validation with UiPath Document Understanding

Signatures are one of the most critical data elements we see in documents every day. There are many use cases for signature verification that require manual involvement. However, UiPath Document Understanding provides the capability to extract and compare signatures in documents within the automated workflow.

The article explains the concept along with a use case. The use case is to extract information in a bank check and compare the signature in the check against a dataset preloaded in UiPath Data Service. You can also find a step-by-step video explaining the entire process at the end of the article.

We use UiPath Document Understanding, machine learning models in AI Center, and Image Processing techniques to extract the signature and perform the comparison.
