Abstract
Embodiments are provided for securely visualizing and routing digital signatures in an electronic document generated by an application program executing on a computer system. The application program may generate an electronic document for receiving a signature graphic, and calculate a hash value from the electronic document and the signature graphic, and create a cryptographic signature from the hash value using a cryptographic encryption method. The electronic document is digitally signed by embedding the cryptographic signature therein. The application program may further collect and route digital signatures by automatically collecting signatures from individual signers, one-by-one, and identify the appropriate signature line for each signer to sign. The application program may further generate a user interface for creating and collecting digital signatures.
