Claim 0:
1. A process for activating a drug measuring device for a user to be tested for drugs, process comprising:
providing the drug measuring device, wherein the drug measuring device comprises an input unit, by means of which a person gives a user sample into the drug measuring device, a testing unit configured to detect a result that a content of at least one predefined substance in a sample given into the drug measuring device is above a predefined limit, and an image recording device configured to take at least one picture of the person who is giving the user sample into the input unit;
providing an activation data bank;
providing a data-processing activation device, which has read access at least at times and write access at least at times to the activation data bank, wherein the activation data bank has an activation data set that is created for the user and the activation data set comprises a reference image set with at least one predefined reference image of the face of a user;
providing an activation phase comprising the activation device receiving an activation image set generated by the image recording device of a used drug measuring device comprising the drug measuring device or another drug measuring device with an image recording device, wherein the activation image set comprises at least one image, which the image recording device of the used drug measuring device has taken and a checking whether the received activation image set meets a predefined release criterion or not, wherein said checking comprises an image comparison between the reference image set for the user and at least one image of the activation image set received;
during the activation phase carrying out the image comparison automatically with the activation device or triggering the image comparison at a distant location in space from the activation device and at a distant location in space from the drug measuring device or carrying out the image comparison automatically with the activation device and also triggering the image comparison at a distant location in space from the activation device and at a distant location in space from the drug measuring device such that a result of the image comparison is detected,, wherein the activation device carries out the image comparison such that the release criterion is met only if at least one image of the activation image set has been recognized as an image that shows the face of the user from the predefined reference image;
with the activation device releasing the drug measuring device for the user if the release criterion is met;
with the activation device completing the activation data set for the user with at least one image of the activation image set, which least one image of the activation image set has been recognized as showing the face of the user if the release criterion is met; and
with the drug measuring device released for the user, using the drug measuring device during a use phase subsequent to the activation phase for carrying out at least one drug test with the use of at least one image comprised by the activation data set for the user.
