Abstract
A process of redacting records based on a contextual correlation with a previously redacted record. In operation, an electronic computing device obtains redaction metadata associated with a previously redacted record and uses the redaction metadata to identify a segment within an unredacted record that was redacted to generate the previously redacted record. The device then processes the segment to detect characteristics of a person or the object captured in the unredacted record and further redacted in the redacted record. The device also determines a context in which the redacted person or object was captured within the segment of the unredacted record. The device then redacts a person or object captured in other unredacted records when such person or object is contextually related to the redacted person or object captured in the unredacted record corresponding to the previously redacted record.
