Abstract
A system and technique may be used to detect whether a skimmer is present in a card reader of an automated teller machine (ATM). An example technique may include capturing an image of a portion of the card reader, generating a set of key points of the image, and aligning key points of the set of key points of the image to corresponding key points in a baseline image to create an aligned image. The example technique may include comparing the aligned image to the baseline image to determine whether a skimmer is present, and outputting a result of the determination.
Claims20
A method comprising:
- capturing, using a camera, an image inside a card reader of an automated teller machine (ATM);
- generating a set of key points of the image;
- aligning key points of the set of key points of the image to corresponding key points in a baseline image to create an aligned image;
- comparing the aligned image to the baseline image to determine whether a skimmer is present;
- and
- in response to determining that the skimmer is present inside the card reader of the ATM, outputting an alert.
An automated teller machine (ATM) comprising:
- a card reader;
- a camera configured to capture an image of a portion of the card reader;
- processing circuitry;
- and
- memory including instructions, which when executed by the processing circuitry, cause the processing circuitry to perform operations including:
- generating a set of key points of the image;
- aligning key points of the set of key points of the image to corresponding key points in a baseline image to create an aligned image;
- comparing the aligned image to the baseline image to determine whether a skimmer is present;
- and
- outputting a result of the determination.
