Patent ID: 7346931

Claim:
A method for transcribing at least one data record of an external data source to a processor unit, comprising: transmitting the at least one data record from the external data source together with additional information to a buffer memory of the processor unit, the additional information including an identifier assigned individually to the processor unit; performing, in the processor unit, a check of an admissibility of a use of the at least one data record based on the additional information; generating a blocking signal when the check indicates that the use of the at least one data record is not allowed; deleting the at least one data record from the buffer memory; and generating an enable signal when the use of the at least one data record is allowed; comparing the identifier, transmitted together with the at least one data record, with a code word from a code word memory having a stored list of code words, the code word memory being of the processor unit to determine whether the use of the at least one data record at the processor unit is allowed, wherein with each check of the identifier in the processor unit another code word is used and therefore each code word identifier is valid only once and no longer available for use.
