Abstract: The present disclosure provides techniques for monitoring transaction data. A first symbol is a symbol is assigned, at a first point in time, to a user device, where, when a user of the user device inputs an item, the user device outputs the symbol.

At a second point in time subsequent to the first point in time, a number of items associated with the user is determined. An audit of the uses is initiated based on determining that a difference between the number of times and the number of items exceeds a threshold maximum difference.
