Abstract

A server transmits a message and attachments from a sender to a recipient. A hash is provided of (a) the message, (b) an identification of the sender and (c) a hash of the attachments to form a data string. Instructions may be included for the recipient to send a hashed encryption of the string to a website at the server by registered electronic mail which provides options to obtain other electronic advantages. To authenticate the message, the recipient transmits the message, the attachments and the hashed encryption of the string to the server website. The server decrypts and detaches the hashed encryption of the string to provide a first string and hashes the message, the sender identification and the hashed attachments in the first string to form a second string. The server also detaches and hashes the attachments from the message received at the server website to form first hashed attachments and detaches the hashed attachments from the string to form second hashed attachments. When the first and second hashed attachments match and the first and second strings match, the server authenticates the message to the recipient.

Claims

1. In a method of providing for an authentication of a message provided by a sender and transmitted electronically via registered mail by a server with file attachments to a recipient, the steps of:

including the message within a data element which allows the message to be reconstructed even if portions of the message are subsequently corrupted.

attachments to the message are included within the data element.

3. A method as set forth in claim 1 wherein

a portion of the message original content is included within the data element.

4. A method as set forth in claim 1 wherein

digital digests of at least portions of the original message are included within the data element.

at least portions of the data element are created by using methods of digital compression.

6. A method as set forth in claim 1 wherein

at least portions of the data element are encrypted.

7. A method as set forth in claim 6 wherein

the digitally compressed portions of the data elements are encrypted.

8. A method as set forth in claim 1 wherein

a digital digest is provided of portions of the data element other than the message.

11. A method as set forth in claim 10 wherein

the data element includes an identification of the sender.

12. A method as set forth in claim 11, wherein

first digital digests of the attachments are included within the data element and are detached from the data element to form first digital digests of the attachments and wherein the attachments are included with the message in a transmission by the recipient to the server associated with the sender and wherein

the attachments are separated from the message at the server and second digital digests are provided of the attachments at the server and wherein

the first and second digital digests are compared at the server and wherein if the digital digests match, the attachments are attached to the message.

14. In a method of providing for an authentication of a message provided by a sender and transmitted via registered mail by a server with file attachments to a recipient, the steps of:

providing at the server the message and the file attachments of the message,

providing at the server a string including an identification of the sender and the message without the file attachments and a hash of the file attachments,

providing an encrypted hash of the string,

attaching the message and the file attachments to the encrypted hash of the string, designated an address at the server where an authentication of the message and the file attachments is to be provided, and

transmitting to the recipient (a) the identification and address of the sender, (b) the message, (c) the file attachments and (d) the encrypted hash of the string for use in subsequently authenticating the message and the file attachments at the recipient.

16. A method as set forth in claim 14 wherein

the sender has the right to select individual ones of a number of different service options including:

Send for Official use Only

Use a Reply Registered Feature

Use a Digital Seal Feature

Send encrypted (with Outlook Security integration), and

Send digitally signed (with Outlook security integration).

15. In a method of authenticating a message provided by a sender and transmitted by registered mail by a server with file attachments to a recipient, the steps at the server of:

providing attachments to the message,

providing the message stripped of the attachments, hashing the attachments,

combining into a string the information identifying the sender, the hashed attachments and the message,

hashing and encrypting the string,

providing instructions in an HTML format of how to validate the message by inviting anyone wishing to authenticate the message to send the message and encrypted hash of the string and the attachments of the message to a particular address at the server, and

introducing the message and the encrypted hash of the string to the instructions in the HTML format, and

sending the message, the HTML file attached to the message and the encrypted hash of the string are sent to the particular address at the server.
