Claim One:
1. A method for de-identification of visual media data, comprising: merging a sequence of images from a set of visual media data into an averaged image; bounding portions of the averaged image that are determined to be relatively fixed, wherein each bounded portion corresponds to identification information located at a relatively fixed position in a plurality of images in the sequence of images, wherein each bounded portion is identified by a corresponding position in the averaged image, and wherein bounding portions of the averaged image that are determined to be relatively fixed further comprises: bounding connected components from the averaged image to find characters and to produce a character image; bounding words from the averaged image to produce a word image, wherein bounding words from the averaged image further comprises: analyzing a portion of the averaged image to obtain a confidence level that the analyzed portion contains text; and establishing the analyzed portion as a word candidate in response to determining that the confidence level meets a word threshold; retaining bounded portions in which a predetermined percentage of bounded characters from the character image and bounded words from the word image overlap; generating a template for de-identifying the sequence of images, wherein the template comprises the bounded portions and the corresponding position for each bounded portion in the averaged image; de-identifying the sequence of images by obfuscating content in the bounded portions; and establishing viewing rights for the bounded portions, wherein at least two of the bounded portions comprise different viewing rights, wherein content in a first bounded portion is visible only to a first set of users, and content in a second bounded portion is visible only to a different, second set of users.
