FIELD: textiles, paper.
SUBSTANCE: covered document contains a substrate, visible authenticating element, as well as a control area which boundaries are at least partially defined by the authenticating element, and the authenticating element, at least partially restricts the contour of the control area and/or is used for positioning the control area. The control area has many identifying elements that differ from the specified authenticating element, and the control area carries the identifying information displaying at least one feature of identifying elements, in particular spatial or physical feature. Identification information is associated with the feature of the control area, in particular spatial and/or physical feature, at that the said information relates to one spatial and/or physical feature of identifying elements. Identifying elements are randomly dispersed within the control area and/or made for emission of a particular signal at the external, in particular optoelectronic, electromagnetic, electrical, magnetic, thermal or acoustic influence.
EFFECT: increased degree of protection of documents against forgery and counterfeiting, improvement of identification while automatic reading of documents.
