    摘要: A method for detecting an electrically and/or magnetically conductive object in a vicinity of a sensor head of a device, having the following steps: emitting a transmitting signal into the surroundings, receiving a received signal as a function of the transmitting signal and the characteristics of the object and the surroundings, analyzing a response signal formed from the received signal. According to the invention, the detection is controlled by providing a class system having a number of classes, which differ from one another in at least one object and/or surroundings characteristic, and classifying instantaneous object and/or surroundings characteristics as a function of the analyzed response signal in a class of the class system, and predefining detection characteristics which are preset in the classified class, a further response signal being detected using the predefined detection characteristics.

    摘要: A method for copy protection includes providing audiovisual or audio data stored in sectors of a record carrier having a file system, and providing additional data to be stored in further sectors. The method includes generating first and second files referencing respective first and second parts of the sectors and respective further first and second parts of the further sectors, so when the first and second files are completely rendered by a playback device, respective first and second parts of the data and respective further first and second parts of the additional data are reproduced. The method also includes determining program instructions, which when executed by the playback device, control switching between reading the first file and the second file, and when the record carrier is an original, switching is controlled so only the sectors and none of the further sectors are read such that no additional data is reproduced.

    摘要: A method for copy protection includes providing audiovisual or audio data stored in sectors of a record carrier having a file system, and providing additional or modified data to be stored in further sectors. The method includes generating a first file of the file system referencing at least a part of the sectors and none of the further sectors, so when the first file is rendered by a playback device, the data is reproduced which is included in the part of the sectors. The method also includes generating a second file of the file system being another file than the first file and referencing at least a part of the sectors and further referencing at least one of the further sectors, such that when the second file is rendered by the playback device the part of the sectors and the at least one of the further sectors are reproduced.

    摘要: The invention relates to a memory authentication method based on a pattern of storage areas of said memory that have altered latencies that are respectively altered such that the respective alteration of the latency of a storage area lies within a measurement noise of latency measurements in respect to the standard latency of said storage area when the measurement is performed with a reading device for accessing said record medium. The verification is then performed by a correlation of the latencies of the altered storage areas with a key used to alter the storage areas.

    摘要: Latency information is used for coding of additional information in a record medium. This additional information which gets embossed in the record medium might be used for verification purposes in that only storage media with the correct latency information are judged to be authentic or might be decoded in a proper way. This technique is applicable to record media, recordable record media, an emulator for recordable or non-recordable record media, a method for producing recordable or non-recordable record media, a method for verifying recordable or non-recordable record media, a record medium writing device for producing recordable or non-recordable record media, and a record medium accessing device for verifying recordable or non-recordable record media.
