Abstract
Systems and methods for validation of a media object may include receiving the media object and detecting, using a sensor, a damaged portion of the media object. The media object may be validated against a standard. During the validation of the media object, the damaged portion of the media object may be given less weight.
Claims17
A method of validation of a media object, the method comprising:
- receiving, at a self-service terminal, the media object;
- passing, by the self-service terminal, infrared light through the media object via a light source associated with the self-service terminal;
- receiving, at a processor of the self-service terminal, a reflective image of the media object and a transmissive image of the media object;
- determining, using an infrared sensor of the self-service terminal, that a security feature of the media object is present;
- detecting, using the infrared sensor of the self-service terminal, a damaged portion of the security feature, wherein detecting the damaged portion of the security feature includes detecting a lack of attenuation of the infrared light passed through the security feature by detecting:
- a white color present in the transmissive image, and
- a black color present in the reflective image;
- validating, by the self-service terminal, the media object against a standard, wherein the damaged portion of the security feature is given less weight during validation;
- and
- accepting or rejecting, by the self-service terminal, the media object based on validation of the media object,
- wherein the damaged portion of the security feature includes a missing portion of the security feature.
8 more elements
A self-service terminal including a system for validating a media object, the system comprising:
- an infrared sensor;
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
- receiving, from the infrared sensor, reflective and transmissive images of the media object,
- determining that a security feature of the media object is present;
- detecting a damaged portion of the security feature based on the reflective and transmissive images of the media object, wherein detecting the damaged portion of the security feature includes detecting a white color present in the transmissive image and a black color present in the reflective image, the white and black colors representing a lack of attenuation of infrared light,
- validate the media object against a standard, wherein the damaged portion of the security feature is given less weight during validation, and
- accepting or rejecting the media object based on validation of the media object,
- wherein the damaged portion of the security feature includes a missing portion of the security feature.
7 more elements
An automated teller machine including a document validation module comprising:
- a camera operable to capture both a transmissive image and a reflective image of a media object;
- a processor operable to:
- receive the transmissive image and the reflective image from the camera,
- determine that a security feature of the media object is present,
- detect a damaged portion of the security feature based on a transmissivity value associated with each pixel of the image, wherein detecting the damaged portion of the security feature includes detecting a lack of attenuation of infrared light passed through the security feature and the presence of a black color for the reflective image and a white color for the transmissive image,
- validate the media object against a standard, wherein the damaged portion of the security feature is given less weight during validation, and
- accepting or rejecting the media object based on validation of the media object,
- wherein the damaged portion of the security feature includes a missing portion of the security feature.
