  • the reader 132 is for executing program instructions 136 that include program instructions 138 that correspond to the program instructions 134 for implementing the access control.
  • the reading device 132 has, for example, a contactless interface 140 for supplying energy to the document 100 by coupling energy into its antenna 112 and for communication with the document 100.
  • the reading device 132 has access to a master key 142 and a user interface 144.
  • the execution of the program instructions 108 starts automatically, as in the embodiment of FIG. 1. Initially, only the first subsequence with the images B1 to Bn is displayed on the display device 102. Even if the second subsequence is to be reproduced with the images b1 to bn, the fulfillment of an access condition is required first.
  • the reading device 132 reads information from the document 100. This can be done, for example, optically by recording data printed on the document 100 or by recording data displayed on the display device 102. These data acquired by the reader 132 are processed by the program instructions 138. For example, these data are linked to the master key 142, so that a symmetric cryptographic key is generated, which is also present in the program instructions 108.
  • the program instructions 138 then generate an access command which is encrypted with this symmetric cryptographic key.
  • This access command is transmitted to the document 100 via the data interface, in particular contactless interface 140.
  • the program instructions 108 attempt to decrypt the access command with the symmetric cryptographic key present there. If successful, the access condition is met and the reader 132 is deemed authorized to access the second subsequence. Thereafter, the images of both the first and second subsequences are successively displayed on the display device 102.
  • FIG. 9 shows a corresponding method, wherein steps 300 to 312 correspond to steps 200 to 212 of FIG. If the check in step 310 shows that the index i is equal to the number of pictures n of the first subsequence, then the flow goes to step 311, where it is checked whether the access condition for accessing the picture data of the second subsequence already exists is satisfied. If this is not the case, the flow returns to step 304, so that the first subsequence of image data B1 to Bn is reproduced again.
  • step 314 in which the index j of the second subsequence is initialized.
  • step 316 the image data set bj of the second subsequence is read and output in step 318 by corresponding driving of the driver on the display device.
  • step 320 it is checked whether the end of the second subsequence has already been reached, namely by comparing the index j with the number of images of the second subsequence m. If not, then in step 322 the index j is incremented and flow returns to step 316. If the opposite is the case, the sequence returns to step 304, so that the first and second partial sequences are reproduced repeatedly in succession via the display device.
