1. A processor-based electronic device implemented method, comprising:
generating, by a processor-based electronic device comprising a hash component, a first hash code having a plurality of digits using a hash function with a content of a document as an input; segmenting, by the processor-based electronic device comprising the hash component, the first hash code into a plurality of groups of one or more digits of the plurality of digits of the hash code; triggering, by a processor-based electronic device comprising a remittance component, a plurality of remittances from a first account to a second account with at least a portion of an amount of each remittance indicating a corresponding group of one or more digits among the plurality of groups of one or more digits; obtaining, by a processor-based electronic device comprising a confirmation component, a record indicating an identity of a party associated with the first account, amounts of the plurality of remittances, and a date of the plurality of remittances; reconstructing, by the processor-based electronic device comprising the hash component, the first hash code based on the amounts of the plurality of remittances as indicated in the record; generating, by the processor-based electronic device comprising the hash component, a second hash code using the content of the document as the input to the hash function; and notarizing, by the processor-based electronic device comprising the confirmation component, the document when the second hash code matches the first hash code. |
