Techniques are described herein for fraud detection which may include generating, from legitimate account data instances, a data compression vocabulary. The data compression vocabulary may specify one or more tokens identified from the legitimate account data instances and a corresponding replacement value. A new instance of account data may be received. Compressed account data may be generated based at least in part on replacing a token identified in the account data with a respective replacement value identified for the token in the data compression vocabulary. Any amount by which the new account data was compressed may be computed and used to make a determination as to whether the new instance of account data is fraudulent or legitimate.
