Methods and devices for providing blacklist information on the suitability of a mobile device for performing analytical measurements

A computer-implemented method of operating a mobile device having at least one camera, the method comprising:

• a. the mobile device requesting, from at least one cloud server, at least one item of blacklist information, the blacklist information comprising information on the suitability of at least one of the mobile device's hardware and the mobile device's software for performing at least one analytical measurement based on an optical detection reaction, wherein the request from the requesting mobile device comprises at least one item of information on the mobile device comprising an individual identifier of the mobile device and the model type of the mobile device;
• b. the mobile device evaluating the item of blacklist information;
• c. if the result of the evaluation in step b. indicates that the mobile device is unsuited for the analytical measurement, the mobile device preventing the analytical measurement;
• d. if the result of the evaluation in step b. indicates that the mobile device is suited for the analytical measurement, the mobile device initiating at least one on-board suitability check for on-board checking the suitability of the mobile device for performing the analytical measurement;
• e. if the result of the on-board suitability check in step d. indicates that the mobile device is unsuited for the analytical measurement, the mobile device preventing the analytical measurement and sending individual check result information to the cloud server, the individual check result information comprising update information on the failed on-board suitability check of the mobile device;
• f. if the result of the onboard suitability check in step d. indicates that the mobile device is suited for the analytical measurement, the mobile device providing clearance information for the analytical measurement;
• wherein the mobile devices of the plurality of mobile devices are grouped into model groups, wherein the blacklist information comprises model-related blacklist information and individual blacklist information, wherein the model-related blacklist information comprises, for the individual model groups, information on the suitability of at least one of the hardware and the software of the mobile devices belonging to the respective model group for performing the at least one analytical measurement, and wherein the individual blacklist information comprises individual information on the suitability of at least one of the hardware and the software of individual mobile devices of the plurality of mobile devices for performing the at least one analytical measurement.
