A method for verifying an object preferably a document, a (bank) card and/or a product package is provided with an electrically conductive security feature on a device with a capacitive surface sensor. After the object with the security feature is placed on the surface sensor, in particular a dynamic input is performed on the object and the electrically conductive security feature using an input means for generating a characteristic time-dependent signal on the surface sensor. The detected time-dependent signal is subsequently evaluated. Furthermore, an object with a security feature or method for its production, system or kit for carrying out the method and for verifying a document is provided with a conductive electrical security feature on a capacitive surface sensor.

In one exemplary embodiment in accordance with the disclosure, an image processing system is configured to use a distance authentication template to execute a detection procedure that detects at least one non-linear distortion in a subject image. The distance authentication template can be generated by mapping a set of spatial coordinates of three features in a distortion-free image to a set of pixel coordinates of the three features in the distortion-free image. Addressing a non-linear distortion in the subject image can include performing remedial actions to remedy the non-linear distortion, or taking into consideration the non-linear distortion when using the distance authentication template to identify one or more features in the subject image.
