    • This invention relates to validation of security papers, documents, banknotes, artworks and brand products. The technical results of the invention are the implementation of the cost-effective and mass-producible security labels with the hidden polarized mono- or multi- color images without any visible outlines of such polarized images, the method of forming said labels, as well as the method of the product authenticity verification with the assistance of the security labels claimed. The claimed security label comprises a sequentially disposed metallic reflective layer and an optically anisotropic transparent substrate, as well as an element able to change optical properties of the said substrate in order to form a hidden polarized image. The element changing the optical properties of the substrate is made in the form of mask that covers a face side of the substrate by the same metallic material that is used for the reflective layer on a reverse side of the substrate. In the second version the claimed security label comprises at least two transparent superposed optically anisotropic substrates, each mask is performed using a solid fill printing method with blank spaces made in accordance with the hidden image graphics. These blank spaces are made in such way that they may coincide or may not coincide for adjacent optically anisotropic transparent substrates, and for each section of such optically anisotropic transparent substrates with the blank spaces in their masks laying under the blank space of the top substrate mask the total optical thickness, Formula (I), where

    • A label for enabling verification of an object or counting objects inside sealed box, includes a scannable region that enables determination of auto-acquired unique spatial orientation of the scannable region with respect to a reference thereby enabling determination of a spatial orientation of the label with respect to the reference. The label is applied onto the object and a change in the spatial orientation of the label indicates tampering of the label, thereby enabling verification of the object. Further, a method for detecting tampering of an object includes providing label on the object. The label has at least a portion which is scannable region with a plurality of patterns and is associated with an external reference point. Further, the method includes determining a first and a second spatial orientation of the label based on computation between the patterns and the reference point, and generating an alert on noticing a change between first and second spatial orientations.
