Systems and methods for check fraud detection

A system for detecting fraud in document processing, the system comprising:

• a processor configured to:
• receive an incoming document image;
• analyze the incoming document image to determine a first score indicating confidence that the incoming document is valid;
• detect a signature on the incoming document image;
• compare the signature with one or more reference signatures to determine a similarity metric;
• determine a signature score indicating confidence that the signature of the incoming document is valid based on the similarity metric;
• determine a fraud score based on the first score and the signature score;
• and
• determine whether to approve or flag the incoming document based on the fraud score.

A non-transitory computer-readable medium having stored thereon one or more sequences of instructions for causing one or more processors to perform:

• receiving an incoming document image;
• analyzing the incoming document image to determine a first score indicating confidence that the incoming document is valid;
• detecting a signature on the incoming document image;
• comparing the signature with one or more reference signatures to determine a similarity metric;
• determining a signature score indicating confidence that the signature of the incoming document is valid based on the similarity metric;
• determining a fraud score based on the first score and the signature score;
• and
• determining whether to approve or flag the incoming document based on the fraud score.
