A security document with a first security element, which includes a first item of visually recognizable and in particular machine-readable information, and a second security element, which includes a second item of in particular machine-readable information which can be used to verify the first item of information. A method for the authentication thereof is also described.

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.

A valuable medium handling apparatus configured to handle a plurality of types of valuable media. The valuable medium handling apparatus includes an inlet configured to deposit the plurality of types of valuable media, a setting unit configured to set the types of the valuable media being handled by the apparatus as a first type or a second type, a determination unit configured to determine whether a type of each of the valuable media deposited in the inlet is the first type or the second type based on the setting result of the setting unit and determine whether the valuable medium determined as the first type is a genuine medium or a counterfeit medium, and a plurality of stackers configured to stack the valuable medium of the type determined by the determination unit, the plurality of stackers including a first stacker and a second stacker.

A method is described for detecting a security thread in a value document, in which magnetic data are employed for sites on the value document, said magnetic data representing a magnetic property of the value document at the site, check sites on the value document are determined employing the sites, and from the check sites, a straight line is specified, along or on which at least some of the check sites lie and which represents a location of the security thread.
