摘要:
The present invention relates to a data carrier (1), especially a security document, such as an identification card, e.g. a passport or a driving license, a credit card and a bank card, the data carrier comprising authentication data (20, 30) comprising personalized data, and as a security feature, an array of lenticular elements (5) being arranged to provide only from predetermined angles of view an image of at least a piece of authentication data of said authentication data (20, 30). In or to make the data carrier (1) impossible or at least very difficult to copy and forge, the array of lenticular elements (5) is provided with a complex structure providing a further security feature.

The present invention relates to a data carrier (1'), especially a security document, such as an identification card, comprising authentication data comprising personalized data, the data carrier comprising a first side (8') and a second opposite side (9'), and a plurality of layers (2a', 3a', 5a', 5b') comprising personalized data, a transparent recording layer (5a'), a transparent plastic upper layer (2a') and an opaque layer (3a') between the recording layer (5a') and the upper layer (2a'). To make the data carrier (1') very difficult to forge and to enable that it can be manufactured with ordinary machines and without need of expensive materials, the opaque layer (3a') comprises a window (7a') a first piece of authentication data of said authentication data being divided between said plurality of layers (2a', 3a', 5a', 5b') so that the first piece of authentication data is to at least one part (10B') thereof, provided above or on the first side of the opaque layer (3a') facing the upper layer (2a'), at least a rest part (10A1', 10A2') of the first piece of authentication data being in the form of laser engraved markings (10A1a', 10A2b') beneath the window (7a') and provided in the recording layer, or in a plurality of transparent recording layers (5a', 5b') of said plurality of layers.

The invention relates to a method of integrating a mark in a document, the method comprising the following steps: selecting a frame to be printed; selecting at least one colour of the frame selected; determining a colour density for each colour selected for the frame selected; for each colour selected, determining a digital code comprising, after printing, the density of the colour; integrating the digital code into the frame of the corresponding colour; and printing the frame comprising the code. In the embodiments, the digital code is a digital anti-copy mark designed to form, following the printing step, a printed anti-copy mark with an error rate of more than five per cent.

The invention provides an authentication unit for reading identification and/or authentication information from a tag or object. The authentication unit includes a near-field reader configured to read a first identification feature based on inherent disorder, and a far-field reader configured to read a second identification feature, such as a bar code, optical characters, or an RFID tag. The near-field and far- field readers may be combined in a single integrated scanning module, which also includes circuitry for receiving signals from the readers, and an interface for communicating with a host device.

A security device, such as a security thread, uses multiple security detection features provided by combining metal and metal/magnetic security features on a carrier substrate. The security detection features basically comprise an optically repeating pattern of discrete metal/magnetic indicia and discrete metal or metal-dot formed indicia. The security detection features may also include at least one metal strip extending along the length of the carrier substrate and/or a plurality of metal dots located on metal-free portions of at least one surface of the substrate.

The method for marking materials comprises: a step (210) for generation of a code, a step (215) for random selection of at least one zone of said material and a step (220) for marking the surface or the core of each zone of the material with a laser beam to represent the code thereon in a manner imperceptible to the naked eye. The random selection step of at least one zone of the material is preferably carried out for each piece of material to be marked. During the step of generation of a code, a two-dimensional barcode is preferably generated and during the marking step, the barcode is represented in two dimensions. According to some embodiments, the method further comprises a step of marking the material in a manner visible to the naked eye, a random selection is made of at least one part of a mark visible to the naked eye and/or said visible mark comprises information relating to the position of at least one zone in which the code imperceptible to the naked eye is represented.
摘要:
The invention relates to a portable data storage medium (1) having a carrier (2) which has a first graphical representation (3) and a second graphical representation (4). The second graphical representation (4) is better protected against manipulation than the first graphical representation (3). In addition, the second graphical representation (4) is in the form of a reference for determining manipulation of the first graphical representation (3). The invention is distinguished by the fact that only a partial region (5) of the first graphical representation (3) laterally overlaps the second graphical representation (4), and there is no lateral overlap between the first graphical representation (3) and the second graphical representation (4) outside the partial region (5).
