A system and method for enhanced security for a self-checkout system is disclosed where predicted weights of items are used to predict the total order weight. The predicted total order weight is compared to an actual weight of the order based on a weighing of the total order, and an output provided

대표청구항 ▼

1. A self-checkout security system for verifying a total weight of a plurality of items in a container, comprising: a weighing unit that measures the total weight of the plurality of the items in the container;a memory storing a list of identification data, including at least a first set of identification data respectively associated with corresponding ones of a first set of items in the container;a storage unit that stores weight data associated with the first set of identification data; anda processing unit communicatively coupled with the weighing unit and the storage unit to compare a predicted weight of the plurality of the items identified in the list to the total weight of the plurality of items in the container, wherein the processing unit is configured to process each of the identification data from the list including: receive from the storage unit the weight data associated with the first set of identification data;compute a mean and a standard deviation for the weight data associated with the first set of identification data;reject from the weight data associated with the first set of identification data, weight data that is more than the computed standard deviation from the computed mean;compute a first predicted weight associated with the first set of identification data as the mean of the weight data associated with the first set of identification data excluding the rejected weight data;compute a second predicted weight associated with at least a corresponding one of a second set of items in the container not having weight data in the storage unit, using a negligible weight as a weight for the at least a corresponding one of the second set of items in the container;compute the predicted weight of the plurality of the items in the container as a sum of the computed first and second predicted weights;comparing the computed predicted weight and the total weight and providing a signal responsive to the comparing; andan indicator coupled to the processing unit so as to be responsive to the signal. 2. The system of claim 1, wherein the weight scale is constructed and arranged to weigh one of the items in the container at a time. 3. The system of claim 1, wherein the weight scale is constructed and arranged to weigh a bag of the items in the container of the order at a time. 4. The system of claim 1, wherein the weight scale is constructed and arranged to weigh all of the items in the container at the same time. 5. The system of claim 1, further comprising a deactivator constructed and arranged to automatically deactivating a theft deterrent device attached to the at least one item in the container. 6. The system of claim 5, wherein the theft deterrent device is an Electronic Article Surveillance tag. 7. A method of verifying a total weight of a plurality of items that have been scanned and loaded in a container for a self-checkout security system, comprising: providing a list of identification data, including at least a first set of identification data, each of which identifying a corresponding one of the items in the container;determining the total weight of the plurality of the items in the container;storing weight data associated with the first set of identification data;processing each of the first set of identification data by: retrieving the weight data associated with a selected one of the first set of identification data; andcomputing a mean and a standard deviation for the weight data associated with the selected one of the first set of identification data and using the computed mean as a first predicted weight associated with the selected one of the first set of identification data;processing any identification other than the first set of identification data by: computing a second predicted weight of items not having stored weight data using a negligible weight for such items; andcomputing the predicted weight of the plurality of the items in the container as a sum of the computed first and second predicted weights; andproviding a security signal based on a comparison of the predicted weight of the plurality of the items in the container and the total weight. 8. The method of claim 7, further comprising: determining if the result of the comparison is within an acceptance threshold. 9. The method of claim 7, wherein the computing of the means and the standard deviation includes: rejecting from the weight data associated with the selected one of the first set of identification data, weight data that is more than the computed standard deviation from the computed mean; andcomputing the first predicted weight associated with the weight data associated with the selected one of the first set of identification data, excluding the rejected weight data.
