A document is provided comprising a machine readable security feature thereon, the document having two or more security elements, each associated with a corresponding identifier detectable from the respective security element, and the machine readable security feature containing document data representative of at least two of the identifiers corresponding to the security elements, to thereby identify at least two of the security elements of the document. Also provided is a method of determining the authenticity of the document, comprising: reading the machine readable security feature to retrieve at least one identifier contained therein; detecting an identifier associated with at least one of the security elements; and comparing the identifier retrieved from the machine readable security feature with the identifier detected from the at least one security element to determine whether the security element identified by the machine readable security feature is present on the document, to thereby determine whether the document is authentic. |
