1. A method for producing a secured data object by means of a data processing device, wherein a digital data stream which comprises a continuous sequence of data sets is received by the data processing system and the method comprises the following steps:
grouping, by a processor of the data processing device, the continuous sequence of data sets into a plurality of intervals, each interval comprised of one or more data sets and having a first interval length; generating, by the processor of the data processing device, at the end of each interval, a respective data representation value for each interval; receiving, by the processor of the data processing device, a first time stamp assigned to the respective data representation value, where the first time stamp is an advanced time stamp; storing the respective data representation value together with the assigned first time stamp on a memory of the data processing device; further grouping, by the processor of the data processing device, the continuous sequence of data sets into one or more larger intervals, each larger interval comprised of two or more data sets forming the plurality of intervals and having a second interval length which is greater than the first interval length; generating, by the processor of the data processing device, at the end of each larger interval, an interval representation value for each larger interval, receiving, by the processor of the data processing device, a second time stamp assigned to the respective interval representation value, where the second time stamp is a qualified time stamp; and storing the respective interval representation value together with the associated second time stamp as a data object on the memory of the data processing device. |
