Shared Bibliography

Please accept the Mendeley invitation to the MIDI private group.

Be sure to create an Elsevier account with the email address David used to invite you. If you want to use an existing Elsevier account, please send David the email address associated with it, so that he can send the invitation to the private group to that address.

Please add relevant publications to the shared bibliography. David will continue to maintain this bibliography.

  • Task Group goals
  • Steering Committee
  • Timeline
  • Discussion

Meeting date: August 10, 2021

WebEx recording of 8/10/2021 meeting

  • Instructions to access the MIDI Task Group wiki page
  • Accept Mendeley invitation to access private group for literature review/annotated bibliography
  • Outline of approach
    • metadata vs. pixel data
    • metadata
    • structured (strongly typed) vs. text
    • pixel data
    • burned-in text ("printed" and hand-written)
    • identifiable features (e.g., faces, iris, retina)
    • with or without "public" data to compare with
  • Challenging topics
    • evaluation of success of de-identification
    • quantitative comparison of performance
    • quantifying re-identification risk
    • creating test data sets
    • faces (etc.) reconstructed from cross-sections
    • burned-in text - detection, removal, cleaning
    • cleaning text descriptors (metadata or burned in)
    • buried metadata (e.g., EXIF, geotags in JPEG inside DICOM)
    • dates (incl. preserving temporal relationships)
    • pseudonym consistency across separate submissions
    • risks of hashing to create pseudonymous identifiers
    • uniqueness of images limits statistical approaches
    • loss allowable during de-identification (e.g., age fuzzing, pixels)
    • private data element preservation to retain utility
    • ultrasound - still frames and cine loops, lossy compressed
    • photographs
    • video
    • gross pathology and whole slide images (incl. labels)
    • IRB/ethics committee messaging wrt. de-identification decisions
    • IT security approval/audits of de-identification
    • regulatory requirements: HIPAA Privacy Rule, GDPR, CCPA, others?
    • sufficiency of standards, e.g., DICOM PS3.15 Annex E
    • risk of not following a standard (home-grown decisions)
    • threat of image "signatures", private set intersection methods
    • policy versus the technical details of recompression/decompression artifacts for JPEG
    • data minimization
  • Inventory of tools
    • user interface vs. scripted (bulk, service)
    • configurable - user vs. installer vs. hard-coded
    • platform, language
    • open source, free, commercial, service
    • on-site vs. outside (e.g., [IP]II needs to leave walls for AI on cloud)
  • Roadmap and deliverables
    • interim report
      • full report
      • "primer" on medical image de-identification for newbies/execs
      • confirm what is out of scope (non-goals) - consent, data use agreements, ...
  • Tasking: Members will think about which task they would like to contribute to.
