A method and system for creating and authenticating a document are disclosed. According to the method, a user of a document creation system is registered to ensure the creation of an authentic document. A document is then created having a user discernable portion and an encoded portion. The encoded portion includes identification data identifying the registered user of the document creation system; as well as contents data corresponding to at least part of the user discernable portion of the document, and authentication data. A central record of the document is created, the record comprising data which corresponds at least partially to the data in the encoded portion of the document. To authenticate the document subsequently, an image of the encoded portion of the document is acquired, for example using fax machine or a camera of a mobile telephone and transmitted to an authentication center. The data in the encoded portion of the document is extracted and the document is authenticated by comparing the extracted data with data in the respective central record. Preferably, the encoded portion of the document contains instructions relating to the authentication process for obtaining biometric data from the respective user of the document creation system. For example, the encoded portion of the document may comprise a password, and the document creator is contacted to generate a live voiceprint of the password to be compared with a stored voiceprint for verification purposes. A system for creating and authenticating a document by the above method are also disclosed. |
