Due diligence in electronic documents
Due diligence 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 conduct the due diligence by comparing the digital signatures. If the digital signatures match, then the due diligence 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 due diligence. Regardless, a result of the due diligence may be incorporated into one or more blockchains.
1. A method, comprising:
generating, by a first server, a cryptographic audit key by hashing a metadata associated with a first version of an electronic document using a cryptographic hashing algorithm;
retrieving, by the first server, a sourcing data associated with a second version of the electronic document;
generating, by the first server, a cryptographic source key by hashing the sourcing data using the cryptographic hashing algorithm;
generating, by the first server, a due diligence file for a due diligence associated with the electronic document, the due diligence file comprising the cryptographic audit key, the cryptographic source key, and an interval of time;
splitting, by the first server, the due diligence file for the due diligence associated with the electronic document into multiple shares via a secret sharing algorithm;
integrating, by the first server, the multiple shares split via the secret sharing algorithm into different blockchains;
transmitting, by the first server, the different blockchains via the Internet to a second server;
storing, by the second server, the different blockchains;
enabling, by the second server, an access to the multiple shares of the due diligence file;
recovering, by the second server, the diligence file from the multiple shares;
invoking, by the second server, a timer associated with the due diligence that increments from an initial value;
determining, by the second server invoking the timer, an expiration of the interval of time specified by the due diligence file; and
disabling, by the second server, the access to the multiple shares based upon the expiration of the interval of time.
2. The method of claim 1 , further comprising determining, by the first server, a minimum number of the multiple shares to be integrated into each one of the different blockchains.
3. The method of claim 1 , further comprising determining, by the first server, a number of the different blockchains based on a total number of the multiple shares split via the secret sharing algorithm.
4. The method of claim 1 , further comprising querying, by the first server, an electronic database to identify the sourcing data.
5. The method of claim 1 , further comprising identifying, by the first server, an Internet protocol address as the sourcing data.
6. The method of claim 1 , further comprising incrementing, by the second server, the timer from the initial value that corresponds to a receipt of the different blockchains.
7. The method of claim 1 , further comprising incrementing, by the second server, the timer from the initial value that corresponds to a read access.
