Abstract
A method for authenticating an object, particularly a security element for protecting value documents, ID documents and products, as well as a security element, a security document, a reader, an individualization device and a server for such a method. The method involves the steps: dividing a first code element into at least one first partial code element and one second partial code element, storing the second partial code element, arranging the first partial code element and/or a second code element on and/or in the object, jointly machine-capturing the first partial code element and the second code element by means of a reader, extracting the first partial code element and the second code element from the data captured by the reader, accessing the stored second partial code element using the second code element as a key, checking whether the code element resulting from merging the extracted first partial code element and the stored second partial code element corresponds to the first code element.
