US 11,687,671 B2 · Method and system for anonymizing raw surgical procedure videos

Abstract

This patent disclosure provides various verification techniques to ensure that anonymized surgical procedure videos are indeed free of any personally-identifiable information (PII). In a particular aspect, a process for verifying that an anonymized surgical procedure video is free of PII is disclosed. This process can begin by receiving a surgical video corresponding to a surgery. The process next removes personally-identifiable information (PII) from the surgical video to generate an anonymized surgical video. Next, the process selects a set of verification video segments from the anonymized surgical procedure video. The process subsequently determines whether each segment in the set of verification video segments is free of PII. If so, the process replaces the surgical video with the anonymized surgical video for storage. If not, the process performs additional PII removal steps on the anonymized surgical video to generate an updated anonymized surgical procedure video.

Dependent claims

A computer-implemented method for verifying that an anonymized surgical procedure video is free of personally-identifiable information, the method comprising:

receiving a surgical video corresponding to a surgical procedure;
removing personally-identifiable information (PII) from the surgical video to generate an anonymized surgical video;
selecting a set of verification video segments from the anonymized surgical video, which includes:
determining one or more time periods within the anonymized surgical video that are associated with higher probabilities to contain PII;
and
randomly selecting the set of verification video segments from the determined one or more time periods within the anonymized surgical video;
determining whether each segment in the set of verification video segments is free of PII;
and
if so, replacing the surgical video with the anonymized surgical video for storage,
if not, performing additional PII removal steps on the anonymized surgical video to generate an updated anonymized surgical procedure video.

7 more elements

An apparatus for verifying that an anonymized surgical procedure video is free of personally-identifiable information, the apparatus comprising:

one or more processors;
and
a memory coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the apparatus to:
receive a surgical video corresponding to a surgery;
remove personally-identifiable information (PII) from the surgical video to generate an anonymized surgical video;
select a set of verification video segments from the anonymized surgical video, which includes:
determining one or more time periods within the anonymized surgical video that are associated with higher probabilities to contain PII;
and
randomly selecting the set of verification video segments from the determined one or more time periods within the anonymized surgical video;
determine whether each segment in the set of verification video segments is free of PII;
and
if so, replace the surgical video with the anonymized surgical video for storage,
if not, perform additional PII removal steps on the anonymized surgical video to generate an updated anonymized surgical video.
