Abstract: A method is provided for producing a secured data object by means of a data processing device. The method includes: generating a data representation value in each case at the end of an interval having a first interval length which is assigned to the data sets of the respective interval of first length, receiving a first time stamp assigned to the respective data representation value, storing the respective data representation value together with the assigned first time stamp, generating an interval representation value in each case at the end of an interval having a second interval length which is greater than the first interval length which is assigned to the data representation values of the respective interval of second length, receiving a second time stamp assigned to the respective interval representation value and storing the respective interval representation value together with the associated second time stamp.

Abstract: The application relates to a method for the electronic archiving of data objects by means of a data processing device, wherein the method comprises the following steps: receipt of a hash value tuple comprising one or a plurality of hash values, wherein each hash value is assigned to a data object, receipt of time information on the hash value tuple indicating a time period within which the hash values of the hash value tuple should be electronically archived and comparison of the time information with a predetermined time specification, wherein archiving steps are carried out if the time information specifies a time period for electronic archiving that is shorter than the predetermined time specification. The application furthermore relates to a computer program product.

Abstract: A method is provided for creating a secure dataset using a software application running on a data processing system, wherein the method comprises the following steps: receiving digital image data (1) that represents one or more images, receiving at least one item of additional information (2) relating to the image data (1), creating a data object (3) that comprises the image data (1) and the at least one item of additional information (2), receiving a qualified timestamp (4) that is assigned to the data object (3), and storing the data object (3) in a data-base together with the assigned timestamp (4).
