The method may be performed by a processor of a multi-function device. For example, the method receives a request to reproduce a document, calculates a perceptual hash of the document, transmits the perceptual hash of the document to a server, receives a control signal to halt reproduction of the document on the printing device in response to a perceptual hash of the secure data stored on the server matching at least a portion of the perceptual hash of the document, and halts the reproduction of the document on the printing device in response to the control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus to prevent reproduction of secure data","description":"A method, non-transitory computer readable medium, and apparatus for preventing reproduction of secure data on a multi-function device are disclosed.
