Abstract
A method, computer program product, and system for providing a security check of items being purchased by a consumer. A digital image of items for purchase arranged on a scale is captured. An estimated total weight and a cumulative center of mass of the items are estimated. An actual total weight and cumulative center of mass of the items are measured using the scale. If the estimated total weight of the items differs from the actual total weight by more than a first threshold amount and/or if the estimated cumulative center of mass of the items differs from the measured cumulative center of mass by more than a second threshold amount, an alert can be output. The alert can include an instruction for the customer or a store employee to rearrange the items on the scale to attempt to resolve the discrepancy.
