A recently granted patent (Publication Number: US11883193B2) outlines a process for activating a drug measuring device for drug testing purposes. The process involves providing the drug measuring device with an input unit, testing unit, and image recording device. An activation data bank and data-processing activation device are utilized to create an activation data set for the user, including reference images of the user's face. During the activation phase, the activation device compares images of the user's face to ensure the release criterion is met, allowing the drug measuring device to be used for drug testing. The process includes automatic image comparison and can be triggered remotely, ensuring the security and accuracy of the drug testing process.

Furthermore, the patent details additional features such as checking for different viewing directions and light conditions in the images, grouping images showing different persons, and selecting images that meet the release criterion. The activation device also triggers the transmission of images to a data processing unit during the use phase for further verification. The system includes an activation device, activation data bank, and drug measuring device, all working together to ensure the proper activation and use of the device for drug testing purposes. Overall, the patented process aims to enhance the security and reliability of drug testing procedures by incorporating advanced image comparison technology and data processing capabilities.
