Abstract: Auditing of mortgage documents is faster and simpler. An electronic mortgage application often contains or references a collection of many separate electronic mortgage documents. Electronic data representing an original version of an electronic mortgage document and its current version may be hashed to generate digital signatures. Any auditor may then quickly compare the digital signatures. If the digital signatures match, then the audit reveals that the electronic mortgage document has not changed since its creation. However, if the digital signatures do not match, then the electronic mortgage document has changed since its creation. The auditor may thus flag the electronic mortgage document for additional auditing processes.

Abstract: Indexing of mortgage documents is faster and simpler for auditing purposes. An electronic mortgage application often contains or references a collection of many separate electronic mortgage documents. Indexing data describing the individual electronic mortgage documents and/or the electronic mortgage application may be hashed and integrated into a blockchain. Any auditor receiving the blockchain may thus perform a reverse lookup to generate an index describing the sections and/or pages within the electronic mortgage application. Moreover, the auditor may also verify a current version of the index to an original version created at creation.

Abstract: Retrieval of mortgage documents is faster and simpler for auditing purposes. Network addresses and other sourcing data may be hashed and integrated into a blockchain. The sourcing data identifies a device, server, or other network location from which the mortgage documents may be retrieved. Any auditor receiving the blockchain may thus perform a reverse lookup to retrieve the mortgage documents. The auditor merely queries for a cryptographic source key to determine the network location storing the corresponding mortgage document.
