Claims18
A computer implemented theft prevention system, comprising:
- a security component that determines a statistical probability of obtaining an accurate net weight of a group of items from a customer;
- and
- a messaging component that automatically notifies store personnel to weigh the group of items if the probability exceeds a pre-defined threshold, the security component initially computes a first value by deducting a weight of at least one item in the group of items measured by store personnel from a weight of the group of items measured by store personnel.
A computer implemented theft-prevention method, comprising:
- directing a customer to proceed to a weighing station based at least in part upon prior shopping history and suspicious activity;
- determining a statistical probability that the customer properly scanned product information into a portable computer terminal;
- notifying store personnel if the probability exceeds a pre-determined threshold;
- and
- computing a first net weight by deductinig a weight of at least one item in a group of customer-selected items measured by store personnel from the weight of the group of customer-selected items measured by the store personnel.

- means for determining a probability that a customer possesses items that have not been scanned by the customer via a portable bar code reader;
- means for alerting store personnel if the probability exceeds a threshold;
- and
- means for a security component initially computes a first value by deducting a weight of at least one item in the group of items measured by store personnel from a weight of the group items of items measured by the store personnel.
