Abstract: An anti-forgery label using random protruding elements and a method for manufacturing the same. A substrate with a printed layer thereon is provided. An adhesive layer is coated on the printed layer, and a plurality of protruding elements are randomly distributed and adhered on the printed layer the adhesive layer. The surfaces of the printed layer and the protruding elements are covered with a light-permeable overcoat layer. A corresponding engaging region is formed in each of the protruding elements where it touches the overcoat layer, and a gap region is formed between the overcoat layer and the adhesive layer in proximity to each of the protruding elements. As such, randomly distributed tactile and visual identification features and irregular deformed identification regions are formed.

Abstract: A tactile anti-forgery method using random raised structures that generates a plurality of labels that can be attached to predetermined products, and each label has a unique label serial number, a label planar printed pattern and a plurality of raised structures randomly arranged on the surface of the label. The various label serial numbers and their corresponding information including the distribution locations of the corresponding; raised structures are established in a system database. A user can connect to the system database via an application in a mobile device, and input a label serial number of a label to be tested to search for the distribution information of the raised structures corresponding to the label.

Abstract: A method for manufacturing an anti-forgery label using random protruding elements. A substrate is provided with an adhesive layer on one side and a printed layer on the other side thereof. A plurality of protruding elements is randomly disposed on the printed layer. A transparent overcoat layer is tightly bonded over the protruding elements and the printed layer to enclose and secure the protruding elements and form effective protection for the printed layer, such that the protruding elements offer a tactile sensation as well as visual identification of the distribution pattern of the protruding elements. In addition, information is provided on at least one surface of the printed layer or the overcoat layer, which, upon analysis, allows a user to connect to a default data storage device in order to obtain anti-forgery information of a product.

Abstract: A tactile anti-forgery method using random raised structures allows a manufacturer to generate labels that can be attached to different products, wherein each label has a unique label serial number, connection information for connecting to a default system database and at least one randomly arranged raised structure protruding from the surface of the label. The label serial numbers and corresponding information such as the distributed location of the raised structures are established in the system database. A user may first confirm the existence of the raised structures by touching the label, and then connect to the system database using the connection information to look up information such as the distributed location of the raised structures corresponding to the label serial number on the label, and finally compare the obtained information and the actual raised structures to see if they are correctly distributed.
