Abstract

Methods and systems for electronic document authentication are disclosed. In one aspect, a method of generating an electronic postmark includes receiving, via a server, a request message from an electronic network, the request message comprising request data including payload data and meta data, generating a timestamp in response to receiving the message, hashing the payload data to generate a payload hash, digitally signing the metadata, the payload hash, and the timestamp to generate a digital signature, generating a response message, the response message generated to comprise the metadata, the payload hash, the timestamp, and the digital signature; and transmitting the response message onto the electronic network.

First claim

What is claimed is:

1. A method of generating an electronic postmark, comprising:
receiving, via a server hardware computer, a request message from an electronic network, the request message comprising request data;
parsing the request data;
identifying, from parsing the request data, payload data and metadata, the payload data comprising data to be authenticated by the electronic postmark;
generating via the server hardware computer, a timestamp in response to receiving the request message;
hashing the payload data to transform the payload data into a payload hash;
creating, in a memory, a new data structure corresponding to the electronic postmark, the new data structure comprising:
a binary message including the payload hash; and
a digital image of an identifier of the electronic postmark, the digital image encoding at least a portion of the request data;

digitally signing the new data structure with a digital signature;
storing the new data structure in a datastore, wherein the stored new data structure comprises the metadata in a metadata field, the payload hash in a payload hash field, the timestamp in a timestamp field, and the digital signature in a digital signature field;
generating a response message, the response message comprising the binary message and the digital image; and
transmitting, via the server hardware computer, the response message onto the electronic network.

2. The method of claim 1 , wherein the metadata comprises one or more of a category of the payload data, a recipient of the payload data, an origin of the payload data, a provider identifier and a mailer identifier.

3. The method of claim 2 , further comprising associating the metadata, the payload hash, the timestamp, and the digital signature as a record, and storing the record in a database.

4. The method of claim 1 , wherein the payload data comprises a direct protocol message.

5. The method of claim 1 , wherein the payload data comprises an email message.

6. The method of claim 1 , wherein parsing the request data comprises one or more of decrypting the request data to identify the payload data and the metadata or identifying a username and password in the request data.

7. An apparatus for generating an electronic postmark, comprising:
an electronic hardware memory configured to store instructions; and
an electronic hardware processor operably connected to the electronic hardware memory and configured to execute the instructions to:
receive a request message from an electronic network, the request message comprising request data including payload data and meta data;
parse the request data to identify payload data and metadata, the payload data comprising data authenticated by the electronic postmark;
generate a timestamp in response to receiving the request message;
hash the payload data to transform the payload data into a payload hash;
create, in the electronic memory, a new data structure corresponding to the electronic postmark, the new data structure comprising:
a binary message including the payload hash; and
a digital image of an identifier of the electronic postmark, the digital image encoding at least a portion of the request data;

digitally sign the new data structure with a digital signature;
store the new data structure in a datastore, wherein the stored new data structure comprises the metadata in the metadata field, the payload hash in the payload hash field, the timestamp in the timestamp field, and the digital signature in the digital signature field;
generate a response message, the response message comprising the binary message and the digital image, and
transmit the response message onto the electronic network.

8. The apparatus of claim 7 , wherein the service oriented architecture module is further configured to cause the electronic hardware processor to decode one or more of a category of the payload data, a recipient of the payload data, an origin of the payload data, a provider identifier and a mailer identifier from the metadata.

9. The apparatus of claim 8 , wherein the wherein the processor further executes the instructions to associate the metadata, the payload hash, the timestamp, and the digital signature as a record, and store the record in a database.

10. The apparatus of claim 8 , wherein the electronic hardware processor is further configured to query the database for records with metadata provider identifiers equivalent to a particular value.

11. The apparatus of claim 7 , wherein the payload data comprises a direct protocol message.

12. The apparatus of claim 7 , wherein the payload data comprises an email message.

13. The apparatus of claim 7 , wherein the processor further executes the instructions to generate the request message to include at least one of a requester account identifier and a billing account identifier.
