Definitions

  • a data carrier having security mark and apparatus for handling such data carrier having security mark and apparatus for handling such data carrier.
  • the present invention relates to a data carrier having a security mark.
  • the invention proposes to use a security mark which is of the optical type.
  • the main idea of the invention is to use a device which is disclosed in the article: "Physical One- Way Function" by Ravikanth Pappu et al., in SCIENCE, Vol.297, 20 September 2002, ⁇ p.2026- 2030.
  • Fig.1 shows a data carrier in accordance with the invention.
  • Fig.2 shows an apparatus suitable for a data carrier shown in Fig.1 , according to the invention.
  • Fig.3 shows another embodiment of an apparatus according to the invention.
  • Fig.1 shows a data carrier according to the invention.
  • the data carrier is an optical disc 1.
  • a mark 2 is put on the data carrier 1. This mark may be put on a dead zone ZD of the carrier, or even on an active zone ZA , in which case the mark has the reference 2' .
  • the mark that the invention proposes in a preferred embodiment is disclosed in the document cited above.
  • Fig.2 shows an apparatus in which a data carrier 1, notably an optical disc, is placed.
  • the data carrier 1 is shown in cross-section.
  • an optical head 10 comprising a lens 12 focuses a laser light beam 14.
  • This optical head 10 is placed in a moving part using a sledge 16 for large displacements and using actuators 20 and 21 for small displacements.
  • the sledge 16 is moved by a motor 17. These displacements are performed in directions indicated by arrows 24 and 26.
  • the head 10 comprises a photo-detector for providing a signal OPT which represents the reflection of the beam 14 onto the carrier 1.
  • This signal OPT is applied to a signal distributor 27, which provides signals for a display unit 30 so that the contents of disc can be displayed together with some other information pertinent to the use of the apparatus.
  • the distributor 27 also provides other signals for the operation of the apparatus, notably for acting on the sledge 16 and on actuators 20 and 21 in that signals TRf and TRr, respectively, are supplied to control devices 35 and 36.
  • a speckle pattern analyzing device 40 which provides an authentication code when the light is reflected from the mark 2. If this authentication is wrong or absent, reading of the carrier is stopped by cutting, for instance, the signal OPT. When actuated, the sledge 16 and the actuators 20 and 21, can position the optical head 10 on the optical security mark. The optical head is thus used for reading the data recorded in the data carrier and for anlyzing the optical mark as well.
  • the first proposed solution is based on the theory of "Physical One Way Functions"
  • POWFs [R.Pappu, et al.] [R.Pappu, et al.] cited above.
  • a coherent laser beam irradiates the optical microstructure, it produces a speckle pattern that can be recorded by a camera.
  • the optical head 10 is used for this purpose, i.e. for analyzing the speckle pattern.
  • the speckle pattern analyzing device 40 applies an algorithm (e.g. based on a wavelet transform) to the recorded speckle pattern in order to turn it into a string of bits. This string of bits is then the unique identification string associated with the disc having the embedded microstructure. It is noted that several bit strings may be derived from a POWF.
  • an additional optical head 60 is provided for analyzing the security mark 2.
  • This head 60 may be in a well defined position along the radius of the optical disc. This is found to be not too limitative for security as the analyzing of the mark is estimated to be strong enough for the authentication.
  • the reading of the stream gives the string that enables the operation of the apparatus.
  • the additional optical head 60 is set to a given wavelength, to a 3D angle, and to a spatial light modulation pattern such that the speckle pattern can be processed. The idea is that such a microstructure is difficult to clone and that it is impossible to simulate the passage of light through such disordered media.
  • the content provider issues content (software, music, movies, ...) on a disc, which also contains an identification string.
  • a microstructure with weak non-linearity properties that is difficult to clone is embedded in this disc.
  • the content provider then stores for various challenges (different wavelengths, 3D angles, ...) the unique fingerprint of the microstructure together with the identification string in a database.
  • challenges different wavelengths, 3D angles, ...) the unique fingerprint of the microstructure together with the identification string in a database.
  • the user of the content asks for some service, he sends his identification string (that he finds on his disc) to the content provider.
  • the content provider then sends a challenge to the user in order to find out whether he is a legitimate user.
  • the owner lets his physical device probe the microstructure in the disc in accordance with the challenge and sends the reply to the content provider.
  • the content provider compares the answers with the responses stored in his database according to the identification string. If the answers correspond to the data stored in the database, the content provider knows that he is doing business with someone who is a legitimate owner of the content. It follows that someone who has copied the content on the disc cannot copy the microstructure, so the protocol will not be successfully finished.
  • the "storage" of a key is claimed. This key is derived from the POWF by irradiations with a laser beam and is embedded in an optical disc.An example is an optical microstructure (weakly non-linear optical medium) which when irradiated with a laser beam gives a unique fingerprint of the structure (as before).
  • the robust part of the speckle pattern may be used as (part of) a key with which the content on the disc can be encrypted.
  • Another embodiment of the invention is to "store" the key by embedding a holographic medium (keys can be stored in contrast in a holographic medium) in the disc in which the key is stored. So the security mark is qualified as being of holographic type. Then the device 40 has to be modified by the application of a unique spatial modulation filter, which has to be put on top of the holographic medium in order to retrieve the key. Again, it is the idea that the structures are difficult to clone and can therefore be used for content protection purposes.
  • the term "security mark” means a mark which can be used for authentication and/or encryption. The authentication mark may be derived by feeding a challenge. The security mark may be used as a key with which the contents of optical disc can be decrypted. Finally, this physical identifier may also be used for disc type recognition.

Abstract

La présente invention se rapporte à un support de données (1) possédant un marquage de sécurité (2) dans lequel est noyé à un code, ledit marquage de sécurité étant de type optique. Le marquage est par exemple du type POWF (Physical One Way Functions) et il crée un effet de type tacheture pour une lumière spécifique. On peut déterminer à partir de cet effet tacheture un code dont on peut obtenir un marquage d'authentification ou une clé déchiffrement. Selon une variante, on peut utiliser un hologramme à partir duquel on peut dériver une clé ou un marquage d'authentification à l'aide d'un filtre de modulation spatiale unique au niveau de l'analyse du marquage de sécurité.
