The apparatus may include a processor, a handwriting input unit operatively coupled to the processor, a display operatively coupled to the processor, a handwriting element module that identifies a handwriting element from handwriting input, an input replication module that controls the display to present the handwriting element, and a privacy module that controls the display to obscure the handwriting element in response to a predetermined trigger event. Obscuring the handwriting element may include removing the handwriting element, rendering transparent the handwriting element, replacing the handwriting element and an area surrounding the handwriting element with a colored area, and/or replacing the handwriting element with an anonymizing symbol. A method and computer program product also perform the functions of the apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure handwriting input for password fields","description":"For secure handwriting input for password fields, an apparatus for using a tone indicator to identify language in text recognition is disclosed.
