A device with an image sensor for detecting of image data as well as a method for authenticating the acquired image data by means of an image sensor

摘要

The invention relates to a device (1) with an image sensor (10) for detecting of image data (110).In order to ensure a reliable authentication of identity of the image data captured by means of the image sensor to enable the device (1) has a surface light modulator (20) with a matrix of micromirrors (21, 26), which in the beam path in such a way (120, 130) in front of the image sensor (10) are arranged, that of the device (1) detected light (100) exclusively in a switched-on state of the respective mirror (23, 26) to a corresponding pixels or pixel area of the image sensor (10) is directed. Furthermore, the apparatus (1) is formed, in the context of an authentication procedure the image sensor (10) by selective a - and / or switching off of at least one of the micromirrors (21, 26) with at least one identification pattern to the actuators of the image sensor (10) acquired image data (110) with the respective identification pattern and to compare an authentication of the detected image data (110), as long as these are consistent with the respective identification pattern.The invention also relates to a method for authenticating by means of an image sensor (10) of acquired image data (110).
