1. A method, comprising:

  • retrieving, by a hardware processor, an electronic document having a portable document format representing a mortgage application including secret data;

    splitting, by the hardware processor, the electronic document having the portable document format representing the mortgage application including the secret data into multiple shares via an electronic representation of a secret sharing algorithm;

    generating, by the hardware processor, hash values representing the multiple shares, each hash value of the hash values generated by hashing a corresponding individual share of the multiple shares using an electronic representation of a hashing algorithm;

    determining, by the hardware processor, a number NR of trusted peer devices as recipients of different blockchains;

    determining, by the hardware processor, a number NB of the different blockchains based on the number NR of the trusted peer devices as the recipients according to a ratio of NR/NB having a maximum value;

    integrating, by the hardware processor, the hash values representing the multiple shares of the electronic document into the different blockchains; and

    publishing, by the hardware processor, the different blockchains via the Internet to distribute the hash values representing the multiple shares of the electronic document having the portable document format representing the mortgage application including the secret data.
