Abstract: Systems and methods for generating and verifying an electronic document with embedded digital signatures. When an electronic document is generated, signature blocks are included that are used to store corresponding digital signatures. When each digital signature is generated, some of the attributes of the signature blocks are filled such that the digital signature references these attributes, such as a timestamp. Each signature block also includes a reconstruct attribute that is used when the electronic document and/or the digital signature is validated through reconstruction. Other signature blocks do not require a reconstruct attribute. During reconstruction, some data is removed from the electronic document such that the data is identical to a previous state. The reconstructed document is hashed and the hash result is compared with the decrypted digital signature. The electronic document and/or the digital signature is validated or verified if the hash result matches the decrypted digital signature.

Abstract: Systems and methods for processing or recording electronic documents that have embedded digital signatures. In an electronic document, signature blocks are used to embed the digital signatures. When an electronic document is received for recordation, the schema and profile of the document are checked. The electronic document or digital signatures are validated by reconstructing the document to a previous state such that the digital signature may be validated. The electronic document is processed and endorsed by inserting endorsement data. The electronic document is digitally signed by the recorder and a receipt is also digitally signed by the recorder. The electronic document is then imaged and indexed. The recorded electronic document and the receipt are returned to the sender using routing information that was included in the electronic document.
