Blood glucose measuring device with reliable transmission of values to an external device
First Claim
1. A blood glucose measuring device, comprising:
- a measuring means for determining measured blood glucose values,a measured value memory in which the measured blood glucose values are stored,a data interface that is configured for a data exchange with an external data reading apparatus, anda data file system which comprises a data reading application that is executed by means of an external data reading apparatus and that is configured to provide the stored measured blood glucose values for reading by means of the external data reading apparatus,wherein the data system file further comprises a test application that is configured to execute an integrity test for the data reading application by forming a current digital signature for the data reading application and comparing this with a digital test signature provided in the data file system and;
wherein the data reading application is configured todownload of the measured blood glucose values to the external data reading apparatus, andprevent a display of downloaded measured blood glucose values if the test application reveals that the current digital signature and the digital test signature inadmissibly fail to match.

8. A method for reading measured blood glucose values from a blood glucose measuring device, comprising:
-
executing a test application formed in a data file system of the blood glucose measuring device, by means of which an integrity test is executed for a data reading application, likewise formed in the data file system, in such a way that a current digital signature is formed for the data reading application and is compared with a digital test signature provided in the data file system, and preventing a transmission of measured blood glucose values from the blood glucose measuring device to the external data reading apparatus, which executes the data reading application, within the scope of the data reading application and/or a display of transmitted measured blood glucose values on an external display means if the test application reveals that the current digital signature and the digital test signature inadmissibly fail to match.
