发明名称 Digitally signing an electronic document with a user-entered signature image
摘要 Methods, systems, and computer program products digitally sign an electronic entity, such as an electronic document, with a user-entered signature image. The method involves rendering the document and rendering a sign dialog. Rendering the sign dialog includes prompting the signer to write a signature to sign the document. The method also involves receiving and inking the signature from the signer, creating a digital representation incorporating an image of the signature; creating a unique value of the image of the signature and of the document, and saving the unique value in association with the document thereby digitally signing the document. The unique value saved in association with the document is verifiable for authenticity by users of the document. Additionally, the method may also involve automatically selecting a signing certificate appropriate for the signer based on selection criteria.
