Abstract: A system for monitoring a person, for example a traveler, who is moving through a facility or a building and carries a biometric travel document and various electronic devices, for example mobile telephones, laptops, tablet computers, e-readers, notebooks, wireless headphones, smartwatches, or fitness trackers. An electronic controller communicates with an input device for inputting contents of the biometric travel document and for forwarding the contents for further processing. An electronically operated database generates a feature space in which the device characteristics are entered by the transceivers as a digital imprint of the traveler and which identifies the traveler with a particular probability resulting from the ratio of a weighted sum of the individual entries in the feature space to the maximum possible sum.

Abstract: A method for rendering visible security information of a digitally stored image which has a plurality of pixels and at least one piece of digitally coded information comprises at least the following steps: allocating at least some of the pixels to at least one image region; determining an average color value of the pixels allocated to the image region; determining two mutually complementary color values whose average color value is at least approximately identical to the determined average color value of the pixels allocated to the image region; depicting the image region and at least part of the digitally coded security information in a visually perceptible manner. The depicted image region thereby has a first of the mutually complementary color values. The part of the digitally coded security information is depicted within the image region and has a second of the mutually complementary color values.
