- Fig. 1 shows a perspective view of the control panel of a self-service terminal with a laterally integrated camera
- Fig. 2 represents the detection range of the camera of Fig. 1;
- Fig. 3 shows the detection area of a camera which detects the control panel from above
- FIG. 4 shows a block diagram of a data processing unit connected to the camera and a video surveillance unit connected thereto.
- Fig. 1 shows in a perspective view of the basic structure of a self-service terminal in the form of an ATM ATM, which has a control panel CP and is equipped with a camera according to the invention CAM for detecting attempts at manipulation.
- the camera CAM is located in a side housing part, the the control panel of ATM ATM framed or encloses.
- To the control panel include in particular a cash dispenser 1, also called shutter, and a keyboard 2.
- a cash dispenser 1 also called shutter
- keyboard 2 a keyboard 2.
- the detection range or angle of the camera CAM comprises at least these two elements 1 and 2 and enables a reliable detection of such manipulation attempts.
- FIG. 2 shows the detection range of the camera CAM from the camera viewing angle.
- the camera is equipped with a wide-angle lens to capture at least these two elements or subregions of the control panel.
- the ATM ATM is designed so that the said elements 1 and 2 preferably have the most homogeneous surfaces with delimiting edges. This simplifies object recognition. By attaching the camera CAM at this particularly suitable position, the subregions or elements 1 and 2 can be optically measured very reliably. It can be provided that the camera is focused in particular on certain areas. An alternative positioning of the camera is illustrated with reference to FIG.
- FIG. 3 illustrates the detection field of a camera which is similar to the camera CAM, but which is now installed in the upper area of the ATM ATM and detects the control panel CP from the top.
- other elements may be provided in the detection range of the camera, such as a Storage area near the keyboard, a card input funnel 4, ie a feeding part for the card reader, and eg a screen 5 or display.

- This data processing unit described later, makes it possible to optimally evaluate the image data generated by the camera so as to make a tampering attempt, such as tampering, with high certainty.
- a superstructure of the keyboard 2 to recognize immediately and possibly trigger alarms and deactivations.
- an optical measurement of the detected elements is carried out within the data processing unit 10 with the aid of the camera CAM in order to be able to clearly recognize deviations in the case of manipulation. Tests by the applicant have shown that even reference deviations in the millimeter range can be clearly recognized.
- Detection of foreign objects scouting camera
- a combination of edge detection and segmentation can be used to thus clearly recognize the contours of foreign objects in the control panel (eg miniature cameras).
- the required image data processing takes place predominantly in the data processing unit described below.
- FIG. 4 shows the block diagram of a data processing unit 10 according to the invention, to which the camera CAM is connected, as well as a video surveillance or CCTV unit 20, which is connected to the data processing unit 10.
- the data processing unit 10 has in particular the following stages or modules:
- the stage 13 is connected to an interface 14, via which various alarm or monitoring devices can be activated or addressed.
- alarm or monitoring devices include, inter alia, a Schmemblschungs- or manipulation detection (IFD).
- the first stage 11, which serves for image processing, is also connected to a second interface 15 via which a connection to the CCTV unit 20 is established. With the help of this CCTV unit, for example, a remote monitoring or remote diagnosis can be performed.
- the data processing unit 10 For the processing of the image data D generated by the camera CAM, the data processing unit 10 is initially responsible.
- the image data D first arrive at the first stage 11, which preprocesses the incoming image data in particular, measures such as shadow removal, edge detection, vectorization and / or segmentation are performed here.
- the downstream second stage 12 serves the feature extraction, which can be carried out for example by means of a so-called Blobanalysis, an edge positioning and / or a color distribution.
- Blob analysis is used to detect contiguous regions in an image and to make measurements on the blobs.
- a Blob (Binary Large Object) is an area of adjacent pixels with the same logical state. All the pixels in a picture belonging to a blob are in the foreground. All other pixels are in the background. In a binary image, pixels in the background have values that correspond to zero, while every pixel other than zero is part of a binary object.
- a classification is made which determines whether or not an enemy manipulation has occurred at the self-service terminal ATM on the basis of the extracted features.
- the data processing unit 10 can be realized, for example, by means of a personal computer which is connected to the ATM ATM or which is integrated therein.
- an additional camera CAMO can also be mounted on the ATM ATM (see Fig. 1), which is directed to the user or customer and in particular detects his face.
- This additional also known as a portrait camera, camera CAMO can be triggered when detecting a manipulation attack to to take a picture of the person at the ATM. For example, once a skimming attack is detected, the described system can perform the following actions:
- the size and nature of the actions taken or countermeasures can be configured by the operator of the ATM via the system described here.
- a single camera installed directly on the control panel (see CAM in Fig. 1)
- several cameras can also be provided there, with a first camera detecting the control panel from outside, a second camera e.g. the
- Tamper detection uses the camera CAM on the control panel and the camera in the card input (not shown here).
- the portrait camera CAMO is also used.
- all cameras have a resolution of at least 2 megapixels.
- the lenses used have a viewing angle of about 140 degrees and more.
- the exposure time of the cameras used in a wide range for example, 0.25 msec. freely adjustable up to 8000 msec (8 sec.). This allows adaptation to a wide variety of lighting conditions. Applicant's experiments have shown that a camera resolution of about 10 pixels per degree can be achieved. Based on a distance of one meter, an accuracy of 1.5 mm per pixel can be achieved.
- the camera CAM mounts rather in the side case of the ATM ATM or in the upper housing area. Also arise depending on the camera position different monitoring options. When monitoring the various elements or subareas, the following is achieved in particular:
- the detection of the cash dispenser (shutter) 1 allows the verification of manipulations in the form of so-called cash trappers, ie special superstructures.
- the detection of the keypad makes it possible to manipulate attempts by superstructures or changes to light protection measures and the like.
- the detection of the support surface makes it possible in particular to detect complete overbuilding.
- the detection of the card input funnel 4, in particular by a camera integrated therein, makes it possible to detect local manipulations.
- Deviations at the rear outer edge of the support surface can be detected as early as 4 mm. Deviations at the lower edge of the shutter can already be detected from 8 mm.
- the data processing unit 10 performs, in particular, a comparison of the recorded image data D with reference data.
- an image of the outside area can be examined for its homogeneity and compared with the image of the outside area of the control panel camera.
- the environment can be examined for a radiation of the illumination for the card entry tray 4.
- the connection of the system to the Internet via the interface 23 makes it possible to remotely control the camera or the various cameras.
- the acquired image data can also be transmitted via the Internet connection to a video server.
- the respective camera virtually acts as a virtual IP camera.
- the CCTV unit 20 described above is used for such a video surveillance facility, wherein the interface 15 to the CCTV unit is designed for the following functions:
- the system is designed so that no false alarms are generated by hands and / or objects in the image during normal operation (e.g., withdrawing money, checking balance, etc.). Therefore, the tamper detection is disabled during the period of normal machine use. Also, in time periods in which, for example, a cleaning or a short-term other use (storage of account statements, interactions before and after the start of a transaction) are not used for tamper detection. Essentially, therefore, only rigid and immovable manipulation attempts are preferably analyzed and recognized.
- the system is designed to work in a wide variety of lighting conditions (day, night, rain, cloudy, etc.). Also, briefly changing lighting conditions, such as e.g.
- the method for manipulation detection performed by the described system has in particular the following sequence (see also FIG.
- an image acquisition (stage 11), wherein the camera parameters are set to to create suitable recordings.
- a series of images or corresponding image data D is recorded, which then serves as the basis or reference for the preprocessing.
- Level 11 which are processed so that they are as good as possible for further processing.
- several images are combined to form a target image and optimized by means of image enhancement algorithms.
- the following steps are carried out:
- Shadow removal, removal of moving objects, removal of noise and / or summary of various exposed shots are annoying and/or recommended to be used as a background.
- the cameras are set to different exposure times to remove reflections and to collect well-lit areas.
- the images are collected over a predetermined period of time to obtain the best possible output images for manipulation detection.
- a feature extraction is performed (step 12) in which image analysis methods are performed on the preprocessed images to validate them for certain features, such as edge positions or color distributions. For each feature, a number or a value can be specified, which indicates how well the corresponding feature was found again in the viewed image. The values are summarized in a so-called feature vector.
- a classification is carried out (step 13), ie the feature vector is passed to a classification procedure to make a decision as to whether there is a manipulation or not. It also uses those types of classifiers that can indicate the confidence, ie probability or certainty, of the decision. Classification mechanisms used can be, for example:
- the system described herein is preferably modular in design to allow for different configurations.
- the actual image processing and the CCTV connection are realized in different modules (see FIG. 4).
- the system presented here is also suitable for documenting the detected manipulations or digitally archiving them.
- the recorded images are stored with corresponding meta-information, such as time stamp, type of manipulation, etc., on a hard disk in the system or in a connected PC.
- messages can also be forwarded to a platform, such as error messages, status messages (deactivation, mode change), statistics, suspected manipulation and / or alarm messages.
- a corresponding message with the respective alarm level can be forwarded to the administration interface or the interface.
- the following options are also implemented at this interface: Query of camera data, such as number of cameras, construction status, serial number, etc., camera master data or setting of camera parameters and / or registration for alarms (notifications).
