Process and devices for activating a drug measuring device, especially an alcohol measuring device

An activation device for activating a drug measuring device for a user to be tested for drugs, 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 the user sample given into the drug measuring device is above a predefined limit, and an image recording device configured to take at least one image of a person, who gives the user sample into the input unit, the activation device comprising:

• a data reception device having read access at least at times and write access at least at times to an activation data bank with an activation data set for a user, which comprises a reference image set with at least one predefined reference image, which shows a face of the user, wherein the data reception device is configured to receive an activation image set that comprises at least one image, which was taken by the image recording device of the drug measuring device or by an image recording device of another drug measuring device, wherein the activation device is further configured:
• to check whether the received activation image set meets a predefined release criterion;
• to carry out, at a time of the checking, an image comparison between the reference image set for the user and the received activation image set;
• to carry out the image comparison automatically and/or to trigger the image comparison to be carried out at a distant location in space from the activation device and at a distant location in space from the drug measuring device, and to detect a result of the image comparison;
• to carry 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;
• if the release criterion is met, to release the drug measuring device for the user;
• and
• if the release criterion is met to complete the activation data set for the user with at least one image of the activation image set, which has been recognized as an image showing the face of the user, wherein the drug measuring device released for the user can be used in a subsequent use phase to carry out at least one drug test with the use of at least one image, which comprised by the activation data set for the user.

An activation system comprising:

• an activation device comprising a data reception device having read access at least at times and write access at least at times to an activation data bank with an activation data set for a user, which comprises a reference image set with at least one predefined reference image, which shows a face of a user, wherein the data reception device is configured to receive an activation image set that comprises at least one image, which was taken by the image recording device of the drug measuring device or by an image recording device of another drug measuring device, wherein the activation device is further configured:
• to check whether the received activation image set meets a predefined release criterion;
• to carry out, at a time of the checking, an image comparison between the reference image set for the user and the received activation image set;
• to carry out the image comparison automatically and/or to trigger the image comparison to be carried out at a distant location in space from the activation device and at a distant location in space from the drug measuring device, and to detect a result of the image comparison;
• to carry 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;
• and
• if the release criterion is met, to release the drug measuring device for the user;
• if the release criterion is met to complete the activation data set for the user with at least one image of the activation image set, which has been recognized as an image showing the face of the user, wherein the drug measuring device released for the user can be used in a subsequent use phase to carry out at least one drug test with the use of at least one image, which comprised by the activation data set for the user;
• a 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 detecting the result that the content of at least one predefined substance the user sample given into the drug measuring device is above a predefined limit;
• and
• an image recording device configured to take at least one image of the person who is giving the user sample into the input unit, wherein the drug measuring device is configured to transmit at least one image generated by the image recording device to the activation device and the activation device is configured to activate the drug measuring device.
