Patent Description:
Faking a scan can include covering the barcode or purposely having the barcode face away from the lens of camera/scanner to appear as though an item is being scanned for security purposes, but the item is not actually scanned.

However, not every missed item barcode scan is problematic during a retail checkout. Sometimes the barcode may not be read and may be manually entered thereafter by a customer or cashier, such that the missed item barcode scan is not problematic and was unintentional in nature.

Still, fake item barcode scans at SST and POS terminals may be, for some retailers, the number one source of theft, and the issue is significant in the industry. In fact, retail theft is a multi-billion dollar problem for the retail industry. It is extremely difficult to detect fake/missed scans and even more difficult to detect when such missed scans were unintentional or intentional.

<CIT> describes item identification using video recognition to supplement bar code or RFID information.

<CIT> describes an item scanning system.

<CIT> describes product scanners that continuously adjust fraud-detection sensitivity levels of fraud-detection processes.

In various embodiments, methods and a terminal are provided for real-time bypass detection in a scanner. Specially, and in an embodiment, an image, captured by a scanner, for an item during a transaction, at a terminal, is attempted to be correlated with an item identifier recorded for the item during the transaction. A determination is made as to whether to raise an alert for intervention during the transaction based on the attempted correlation.

Aspects of the present invention will be apparent from the following description, given by way of example, with reference to the accompanying drawings.

<FIG> is a diagram illustrating components of a real-time bypass detection in a scanner system <NUM>, according to an example embodiment. It is to be noted that the system <NUM> is shown schematically in greatly simplified form, with only those components relevant to understanding of the embodiments being illustrated.

Furthermore, the various components (that are identified in the <FIG>) are illustrated and the arrangement of the components is presented for purposes of illustration only. It is to be noted that other arrangements with more or less components are possible without departing from the teachings of real-time bypass detection in a scanner, presented herein and below.

Furthermore, the techniques and the systems presented herein and below (for real-time bypass detection in a scanner) may include all or some combination of the components shown with the system <NUM>. The methods are programmed as executable instructions in memory and/or non-transitory computer-readable storage media and executed on one or more processors associated with the components/devices.

Specifically, the system <NUM> includes a terminal <NUM>, a transaction manager <NUM>, a scanner <NUM> having an item scan manager <NUM>, and a bagging area detection mechanism <NUM>.

Existing retail-based terminal systems count the number of items that pass in front of a scanner or that is in front of the scanner; however, these systems fail to correlate any of the items with a detected barcode.

Various embodiments presented herein, detect when an item passes in front of a scanner/camera and correlates the item with a barcode read to determine if the bypass was intended as fraud (theft). Embodiments, presented herein, also provide mechanisms for determining when missed barcode reads are accounted for and therefore unintentional and not problematic.

The process proceeds as follows, in one embodiment:.

In an embodiment, (<NUM>) can be performed in a variety of manners. For example, the scanner <NUM> maintains an image as a reference image for what the field of view looks like (image) when there is no item present, such that when an item is placed within the field of view, the reference image is changed. The scanner <NUM> can include a motion detector to detect motion in proximity to the scanner to trigger an image being taken. Three dimensional cameras can be used. Infrared sensors can be integrated into the scanner <NUM>. Other techniques can be used as well.

Conventional approaches perform the processing of (<NUM>) and (<NUM>) but not for purposes of item bypass detection; rather such processing is used for regulating the scanner's sleep mode and for turning off illumination of the light sources for the scanner. In fact, conventionally analytics are used for bypass detection, such systems are not processed within the scanner and they are not real time so as to detect the bypass scanning during a transaction to prevent such bypass scanning.

The processing correlates barcodes to item swipes to determine when bypass scanning is occurring at the terminal <NUM>. This processing is performed within the scanner <NUM> and/or, in some cases, within the scanner <NUM> and the terminal <NUM>. The processing is achieved in real time, so as to prevent shoplifting before it occurs (customer leaves the store).

In an embodiment, the above processing (referred to herein as "bypass item scan processing") is further enhanced for determining when a bypass item scan is unintentional or otherwise accounted for during the transaction. The processing referenced below is referred to herein as "enhanced bypass item scan processing.

With the enhanced bypass item scan processing the bagging area detection mechanism <NUM> is utilized as discussed herein and below.

A true bypass item scan means: (a) the operator (cashier or customer) pretends to scan an item but does not scan the item, and (b) the missed item is placed in the bagging area of the terminal <NUM>.

From the point of view of the scanner <NUM>, a true bypass item scan appears similar to an unintentional failed scan because: (a) the operator tries to scan the item barcode but due to barcode positioning or poor print quality of the item barcode, the item barcode failed to scan and appears to the scanner to be a bypass item scan; (b) the operator repeats (a) until the barcode is properly read by the scanner <NUM>; and (c) the operator places the item in the bagging area of the terminal <NUM>.

There are other motions at the terminal <NUM> during a checkout that can also be misinterpreted by the scanner <NUM> as a bypass item scan, such as: (a) the operator tries to scan the item but cannot scan the item because of a poor quality barcode, (b) the operator hand keys in the barcode into the terminal <NUM> (through a terminal keypad or touchscreen peripheral), and (c) the operator puts the item into the bagging area. In still another situation: (a) the operator tries to scan the item but cannot due to a poor quality barcode, (b) the operator uses a handheld scanner also available at the terminal <NUM> to scan the item (handheld scanners can sometimes read barcodes that bioptic scanners cannot), and (c) the operator places the item into the bagging area of the terminal <NUM>. In yet another situation, the operator may have multiple items that are the same type and brand of item, such that the operator: (a) sees that the operator has multiple items that are the same item, (b) the operator scan just one of the items and then keys in an item quantity, (c) the operator puts all of the items into the bagging area (note with this situation some of the multiple items may actually pass within the field of view of scan zone of the scanner <NUM> and appear to be one or more bypass item scans during a transaction). There is still yet another situation in which an action during a checkout at the terminal can be misinterpreted as a bypass item scan this is when a produce item is entered: (a) the operator places the produce item on the scanner weight plate (note that this is a case where the scanner <NUM> is a dual scanner and weigh scale integrated as a single device), (b) the operator keys in the produce item's PLU (note that (b) may come before (a) in some terminal <NUM> configurations), (c) the terminal <NUM> measures the sale weight for the produce item, and (d) the operator moves the produce item to the bagging area of the terminal <NUM>.

In the enhanced bypass item scan processing data fusion is processed to reduce false alarms and improve the accuracy of the bypass item scan processing presented above by utilizing a bagging area detection mechanism <NUM>.

The bagging area detection mechanism <NUM> can include one or more of the following type devices that are interfaced to the terminal <NUM>: a security scale in the bagging area, an optical beam sensor at a takeaway conveyance belt of the terminal <NUM>, a motion detector, an intelligent camera that monitors the bagging area of the terminal <NUM>, a vibration sensor attached to the bagging area of the terminal <NUM>, a sensor that detects security tags on the items in the bagging area of the terminal <NUM> (the sensors can be connected to the terminal <NUM> and/or the scanner <NUM>).

The enhanced bypass item scan processing utilizes data points provided by the bagging area detection mechanism <NUM> during checkout at the terminal <NUM> by adding processing to (<NUM>) of the bypass item scan processing (discussed above) to include:.

The enhanced processing of (e) and (f) are added before (<NUM>) of the bypass item scan processing raises an alert for assistance in real time at the terminal <NUM> during a transaction. This increases the accuracy of bypass item scan detection and reduces false positives for a transaction.

"Bagging area fail-safe event" is intended to mean that the system <NUM> has not detected an item in the bagging area, presumably because the customer still has the item in the customer's hand. There are two processing paths for detecting this fail-safe event. The first path "no item detected in the bagging area" means the bagging area detection mechanism <NUM> does not detect the item in the bagging area before a next bypass scan event is detected by the scanner <NUM>. The second path "item detected in the bagging area but then removed" means the bagging area detection mechanism <NUM> detected an item in the bagging area, and then detected the operator removed the item before the next bypass item scan or scan event.

"Terminal fail-safe event" is intended to mean that the transaction manager <NUM> and/or item scan manager <NUM> has detected and determined an unusual event. Such events include: item scanned via a handheld scanner, a single barcode was keyed in for multiple items that are the same item, a produce item was entered (keyed in). Note in some configurations the item scan manager <NUM> detects handheld scan when the handheld scanner is directly interfaced to the scanner <NUM>.

It is noted that the enhanced bypass item scan processing is particularly valuable in the industry because: assisted-service terminals (POS terminals) do not have bagging security scale intervention processing, many retailers are disabling SST bagging security scale interventions because customers are becoming annoyed with the many security exceptions being raised during SSCOs, many SST attendants routinely override bagging security scale alerts because of the large number of false positives generated by the existing bagging security scale systems, and many SSTs lack any bagging security scale system in the industry.

Again, the enhanced bypass item scan processing improves the bypass item scan processing by accounting for a number of potential situations during checkout that are not situations in which an item is being bypassed for non-payment at the terminal <NUM> (reduces false positives of the bypass item scan processing as discussed above).

In an embodiment, the terminal <NUM> is a POS terminal operated by a cashier that assists in checking out a customer at a retailer during a transaction in which items are being purchased from the retailer.

In an embodiment, the terminal <NUM> is a SST operated by a customer that is performing a SSCO with a retailer during a transaction in which items are being purchased from the retailer.
