Automated document redaction

摘要

Document redaction includes identifying within a computer-based document stored on computer-readable storage medium, a candidate redaction element that is of a predefined redaction element type, identifying an evaluation element that is of a predefined evaluation element type and that is associated with the candidate redaction element, identifying a predefined logic expression that is associated with the redaction element type and that operates on the evaluation element type, evaluating the logic expression which generates a value, identifying a predefined permission expression that is associated with the logic expression, that operates on the value, and that is associated with a recipient role, evaluating the permission expression, which identifies a redaction directive, and applying the redaction directive to the candidate redaction element within the computer-based document prior to the computer-based document being provided to a recipient having the recipient role.

1. A document redaction method comprising:
identifying within a computer-based document stored on a computer-readable storage medium, a candidate redaction element that is of a predefined redaction element type; identifying an evaluation element within the document of a predefined evaluation element type and that associated with the candidate redaction element, wherein the evaluation element of the candidate redaction element associates one evaluation element type of information with the candidate redaction element; identifying a predefined logic expression that is associated with the redaction element type and that operates on the evaluation element of the evaluation element type; evaluating the identified predefined logic expression by a processor, wherein the evaluating includes generating a value for the predefined logic expression; identifying, for the predefined logic expression, a predefined permission expression that is associated with the predefined logic expression that operates on the value and that is associated with a recipient role; evaluating the permission expression, wherein evaluating the permission expression includes identifying a redaction directive; and applying the redaction directive to the candidate redaction element within the computer-based document prior to the computer-based document being provided to a recipient having the recipient role.
