Description of the Invention: [Technical Field] The present invention relates to an information carrier relating to a reproducing apparatus and method for reproducing payload data from an information carrier and relating to a method for manufacturing an information A device and method for producing a carrier. [Prior Art] The need to protect usage rights by means of digital rights management (DRM) is increasing. As described in WO 2006/064412 A1, DRM can be network-centric, card-centric, device-centric, or media-centric. In the case of media-centricity, digital rights are stored separately on the media. A typical attack on such a media-centric DRM solution is the so-called "storage and restore", which generates a raw information carrier (also referred to as a storage medium), which is stored on a CD such as _ disc. An image of one of the discs on all channel bits. The image is a copy of one of the pieces of information, without interleaving the bit. This image is written on a blank information carrier to make a copy. One way to solve this intrusion is to use the -hidden channel (HC) method as described in W〇 〇 2/〇15184 ai. The Hc is a side channel (SC) on the storage medium for storing the information required for the video. Since the user cannot write - SC ', the DRM information is lost in a store and restore attack. SUMMARY OF THE INVENTION The present invention is directed to providing an information carrier, a seed weight (four), and a method of 146, 596. doc 201040787, and a manufacturing apparatus and method that allow for the security protection of data on an information carrier and also provide resistance Protection against storage and restore attacks. In the -th aspect of the present invention, a (four) message carrier is provided, and a payload data stream stored thereon includes: - payload data, the payload data is stored in the block according to a first format And the first format is adapted to be reproduced for use by a reproducing device that reproduces data in accordance with the first format; and 混淆 混淆 confusing data is stored between the blocks of valid payload data, wherein The obfuscated data does not contain actual payload data and is stored according to the second format, which does not allow the reproducing device to distinguish between the obfuscated material and the payload stored according to the first format; A confusing material adapted to record data in accordance with the first format is used to harden the confusing data and store the confusing data on another information carrier. In a further aspect of the invention, a reproducing apparatus for reproducing from an information carrier on which a payload data stream is stored is presented, the apparatus comprising: a picking member for The information carrier reads the payload data stream; and solves the parent error component 'which is used to reproduce the payloads stored in the block and ignores the blocks stored in the payload data. Mixed information. In a further aspect of the invention, there is provided a manufacturing apparatus for manufacturing a beryllium carrier according to the invention, the apparatus comprising: _ 146596.doc 201040787 - a staggered member for using payload data with The obfuscated data is interleaved into a payload data stream in which the payloads are disposed in the block and the obfuscated data is disposed between the blocks; - a recording component, which is used The payload data stream is recorded to the information carrier, wherein the payload data is stored according to a first format, and the «Hai format allows for adaptation to a weight based on the data of the first format. The device now reproduces, and the obfuscated data does not contain the actual payload data and is stored according to a second format that does not allow the reproducing device to distinguish between the obfuscated material and the payload stored according to the first format. Information and does not permit the adaptation of the obfuscated material by a recording device adapted for recording in accordance with the first format and storing the obfuscated material on another information carrier . According to a further aspect of the invention, a corresponding method of reproduction and a corresponding method of manufacture are presented. Preferred embodiments of the invention are defined in the accompanying technical solutions. It is to be understood that the methods and devices of the application have preferred embodiments that are similar and/or identical to those of the claimed information carrier and those defined in the accompanying claims. The present invention is based on the idea of creating a hidden channel (HC) by hiding copy protection data in one of the areas containing confusing data (or patterns). A confusing pattern is a type that seems to contain information but does not actually contain it. This confusion pattern is significantly different from the traditional recording pattern, and it is difficult to distinguish between the mixed type and the area that does contain information. A boundary condition of the obfuscated pattern is that it must be written along a track and the driver (ie, the recording device and/or the reproducing device) 146596.doc 201040787 must be able to follow this magnetic hold. According to a preferred embodiment, the second format is adapted such that it does not allow the reproducing device and the recording device to reproduce the obfuscated data. In other words, adapted to be reproduced for data according to the first format. /Reproduction and recording of records. Devices are often unable to reproduce such obfuscated material. Such devices will need to be rigorously modified to allow for reproducible data, which makes it very difficult and costly for a developer/producer of such devices to implement this functionality. In addition to this Q, there is usually no other reason to implement this functionality except to circumvent the reasons for this privilege protection. This functionality will therefore be relatively simple to detect such privilege protection violations. The distance between the blocks storing the confusing material is fixed and predetermined according to another preferred embodiment. In this case, the compliant device then only needs to learn the distance information to read the actual payload data and ignore the obfuscated data. This distance information can be provided, for example, via an external link (eg, by content owner or other The authorized authorized unit to provide).艮 艮 According to the embodiment, the distance between the blocks is variable. In this case, the distance may be obtained depending on a certain one associated with the reproducing device and/or the recording device. Therefore, only a specific device can determine the correct distance information and since the other (non-compliant or illegal) device does not (for example, via the H寅 algorithm) lead to the correct distance information, the Y device is not enough. Determine the correct distance information. At this time, the embodiment does provide authentication for a certain 4b, enthusiasm and flexibility but refuses to access other devices to the information carrier. Preferably, the ancient 4 A i... > load information contains copy protection data or digital rights 146596.doc 201040787 official information. However, information can often be applied to the protection of other messages. The reproducing apparatus according to a preferred embodiment of the present invention includes a distance determining member for determining a distance between the blocks of the payload data, wherein the reading member is adapted to use the determined distance to only The payload data stored in these blocks is read and reproduced and the obfuscated data is ignored. Preferably, the distance determining means is adapted to determine the distance from a distance information stored in the information medium j. However, if the reproducing device is a compliant device, the distance information is stored in the reproducing device itself; or the distance information may be provided from an external device or an authorized unit, as mentioned above. According to another embodiment, the distance reproducing means is adapted to determine the distance by using a multiplication factor indicating that the distance is a product of a multiplication factor multiplied by a unit length, In other words, the multiplication factor is multiplied by the product of the -channel bit length or the wobble period. In particular, the frequency of the bit clock used to determine the hidden channel (i.e., the channel that stores the right save payload and is hidden by the use of the mixed material) is multiplied. This has the advantage of obtaining an m-time clock that allows for a higher information density. In the case of Checheng Jia, the distance judgment Acer includes a phase-locked loop (PLL) to provide % order information. The PLL will provide this timing. The reproducing device can determine the start and end of a block based on the timing information. Because no, 'because material, the frequency of several blocks is better than the product of the timing information frequency and the multiplication factor.

Figure 3 /, payload data stream E 'The payload data stream e /, the political load data C block C1 to C4 and the confusion data D block D1 to D4 intersection #t above 8 ° in the payload data A 146596.doc 201040787 constant or variable interleave distance d can be used between blocks C1 to C4 of C. The distance dl to d5' is indicated in the example illustrated in Fig. 3, where the distance d indicates the beginning or end of a block containing the payload data c. Therefore, the payload data stream E can be regarded as a hidden channel for hiding the payload data C by using the confusing data D of the error. It should be understood herein that a variable interlacing distance d may be specified depending on the driver/supplier ID', i.e., a specific identifier of the driver or the driver for the deer. It should be further understood that interleaving also enhances the integrity of data readouts because burst errors (to marks, fingerprints) affect only a small portion of the data. 4 is a block diagram of a reproducing apparatus 3 〇 according to an embodiment of the present invention. The reproducing device 30 includes a reading unit 32 for reading the channel data stream g from the information carrier 20 and for separating the content data ρ from the payload data stream E from the parent error. The content data can then be further processed (e.g., decoded, demodulated, and reproduced) in a common and known manner as desired. The selection between the content data F and the data of the payload data stream E is based on a control signal S. A payload data stream E to a de-interlacing unit is then provided for deinterlacing, reproducing the payload data C, and ignoring the obfuscated data D between the blocks stored in the payload data C. The deinterlacing unit is typically associated with the interleaving unit 16 of the manufacturing apparatus 10. For the deinterleaving and reproduction of the payload data, the deinterleaving unit 36 needs some information as to how and/or where to find the valid payload data c in the payload data stream E. Preferably, the distance information d is provided to the deinterleaving unit 36 to inform the deinterlacing unit % about the effective negative 146596.doc • 12· 201040787 the distance between the blocks of the data and thus the effective reproduction The beginning and end of such blocks of load data c are such that blocks that are considered to be interlaced are only negligible for containing the obfuscated data D. The distance can be stored in the reproduction device 30 directly or indirectly as information about the distance, or can be read from the information carrier 2, which can be stored, for example, on the information carrier 2 A hidden location known to the reproducible device. In a further embodiment, h is explicitly illustrated in Figure 4, Ο providing a distance determining unit 34 for use based, for example, on an information carrier or a self-contained entity 18 (such as a content owner or any other The authentication authority is used to determine the payload data for some distance information provided. The distance between the blocks. * For example, in an embodiment, the distance determining unit 34 may be adapted to determine the distance by using a multiplication factor indicating that the distance is the product of the multiplication factor multiplication - unit length The unit length can be: channel bit length or swing period. Of course, other unit lengths that are available or appropriate may also be used. i As mentioned, 'If the wobble (which is generally known in the art of optical recording media) is added to the magnetic hold containing the hidden channel, the distance d = = can be set. The table _ continuation method _ can be by using any :, the length of the early bit (for example, equal to the length of the channel bit), the unit length is dared to enter the confusing pattern of the time, the mouth. Timing information can be retrieved in a PLL manner. The timing can only be concealed in the confusing pattern by placing only the spleen and the subset of the edge (rising/falling) into the obfuscated pattern on the grid. This is illustrated by the diagram depicted in Figure 5. – LL is fed back by the 146596.doc -13· 201040787 zero-point parent fork indicated by f(n) (Gate Control), where f(n) is a scalar quantity that points to the zero point that will be used. Therefore, after the last used edge (9) 2 · 6) = 3 4 4 t 4), the PLL will be locked to the edge of f(n)_th. The information about which edge the pLL will be locked on is typically embedded in the key signal K (i.e., the key provided, for example, in the rendering device 3 or via the link by the third party 18). f(n) can be driver/vendor specific, allowing different drivers to use different timings. The advantage of this solution over existing solutions is that the obfuscated pattern will cause a pirate who attempts an illegal copy of the information carrier. Note that by making these patterns difficult to reproduce, it is economically no longer attractive to pirates to attempt to copy information carriers. In addition, there is great freedom to change the confusion without compromising the principles underlying the creation of hidden channels. The designer of the system can use the appropriate-modulation code (cf. Figure 3) for the payload data of the block. An example can be used for the use of spread-spectrum spread-type modulation due to its robustness. And the knowledge and if the ID) is difficult (the solution) can be based on the driver/supplier is difficult: measured. Or, you can use a simple (four) early L-horse error correction combination). Preferably, the right load data C (e.g., the data bits ', are repeated to ensure a sufficiently low - bit error = a number of squares).

The advantage is that a higher bit clock that allows for a higher information density can be obtained. Imagine the following situation. The distance between multiple pieces of timing information (represented as f(i), f(2), ... in Figure 6) is separated by t milliseconds. This corresponds to a frequency of 1 kHz. To get a one-dimensional clock of 1 〇 112, use a multiple of the factor 丨〇 in the PLL. This multiplier factor can be secret (e. g., a key), standardized, provided via an external link, or provided by the payload owner as explained above.接下来' Next, two specific embodiments will be explained. According to the embodiments, the material is stored on the _disc according to a specific standard (referred to as channel code) (10) for all standardized channels of optical storage. The common point of (4) is that the standardized channel code is the binary level and the discrete operation is used (4)-). In the embodiment, # is used by using an obfuscated pattern: With this property' the obfuscated pattern uses more than two levels. When the payload data c is reproduced, the multi-level message (which is inverted with time) is translated into a binary signal by comparison with the second slice level SL. If the signal level exceeds the limit level SL Then obtain the first-second level (for example, in all the other cases, the signal level is obtained by the other-binary value (for example, 〇). Therefore, the 'reproduction device cannot distinguish between the confusing and the first- The format (ie 'using a standardized format with only two (binary) levels) stores the payload data C. Further, a record adapted to be used for root-146596.doc •15·201040787 data records It is also impossible for the device (using only the binary level) to copy the obfuscated data and record the obfuscated data on another information carrier, ie such recording device cannot apply multi-level recording. According to applicable to optical storage The second embodiment of the media utilizes the properties of discrete run lengths for all channel codes used for optical storage. Two waveforms are shown in Figures 7A, 7B. The diagram shows an optical storage standardization One of the typical waveforms of the track code, Ti. Clearly aligns the transition on a grid. This results in a discrete run length with a limit on the minimum run length and maximum run length (not shown in this figure). The limitation on the minimum run length and the maximum run length is generally known and referred to as the heart moxibustion constraint. The second signal 2 depicted in Figure 7B is shown in the second case where the transition will be delayed and deviated from the grid. The clasp is therefore not so discrete that the second signal T2 is significantly different. However, it should be noted that the transition on the grid is never perfect due to noise, but the standard variation is generally very small. The purpose of the embodiment is to clearly deliberately defer the transition from the grid. Further, t' may have different limits on the minimum run length and/or the maximum run length. / /, according to this embodiment It is not possible to distinguish between obfuscated material and payload data stored according to the first format (ie, the standard format in which the transition is aligned along the network). Further, 'for adaptation to be used for the first format It is also impossible to copy the obfuscated data and record the obfuscated data on another information carrier. Such a recording device cannot intentionally deviate (4) (4) from the grid. 146596.doc -16- 201040787 It should be noted here that different examples besides optical storage may be applied for the application. According to a further embodiment, different messages may be interleaved in the channel. The message read by the device may be reproduced. Depending on the ID/permission of the message. For example, if a _ disc sold in the US is replayed in a European player, the player in Europe is due to its different (European) ID. The disc may not be played by reading a different code. This green is shown in Fig. 8 in Fig. 8 illustrating a channel stream e according to this embodiment. The blocks D1 to D5 of the confusing material here are interleaved with the blocks C1 to C3 containing the payload data blocks CA1 to CA3 for the US player and containing the effective load for the European player. The player can then select a block with payload data based on its selection.
