Abstract:
1. A method for verifying machine-readable data using a processor and a memory, the method comprising the steps of: storing a first data value in the memory, the first data value associated with a first data field; storing a second data value in the memory, the second data value associated with a second data field; marking, using the processor, the first data field and the second data field as not uncertain; storing a formula in the memory, the formula defining a relationship between the first data field and the second data field; applying, using the processor, the formula to the first data value and the second data value for determining whether the formula evaluates as true or not true; marking, using the processor, the first data field as unverified and the second data field as unverified if the formula evaluates as not true; calculating, using the processor, a determined value for the first data field using the formula if the first data field is marked as unverified and if the first data field is marked as not uncertain; and marking, using the processor, the first data field as uncertain if the determined value for the first data field does not match a previous determined value for the first data field.
