Estimated time: 40 minutes

Overview

Questions

  • How do I share classified data with external collaborators?
  • Can I use Google Drive or Dropbox for research data?
  • Are there restrictions on sharing with international collaborators?
  • How do I publish my data while protecting privacy?

Objectives

  • Share data with collaborators while maintaining security
  • Use institutional cloud storage (Box, OneDrive) with encryption
  • Recognize international data transfer restrictions
  • Write appropriate data availability statements

The Sharing Problem


Research is collaborative. You need to share data with PhD students at other universities, industry partners, international collaborators, funding agencies, journal reviewers, and other research groups. But you also need to protect classified data. This episode shows how to do both safely.

A flow beginning when someone asks for your data. Classify it first, then follow the tier: PUBLIC can be shared freely; PROPRIETARY needs PI approval and then a secure transfer; RESTRICTED needs IRB approval and a data use agreement, and may only travel over an encrypted channel. A warning says never to email RESTRICTED data or leave it in a shared folder to sort out later.
Classify before you share, not after someone asks.

Quick Reference: What Can Be Shared?

Classification Can Share? Restrictions
Public Yes, freely None
Proprietary With permission Requires collaboration agreement
Restricted NO Not without de-identification and approval

Core principle: Restricted data (FERPA, CUI, PII, export-controlled) cannot be shared in its original form.

Sharing Public Data


Can be shared: Freely, with anyone, any method

BASH

# Post on GitHub, Zenodo, OSF, or institutional repository
# Email directly
# Upload to shared cloud storage
# Include in paper supplementary materials

Sharing methods for data shared within groups: 1. Sagehen HPC direct access (collaborators get accounts) 2. Pomona-managed Box or OneDrive 3. Secure SFTP transfer via ITS 4. GitHub or public repository (if fully public)

Sharing Proprietary Data


Sharing with External Collaborators

Requires: 1. Collaboration agreement (contract) 2. Secure transfer (encrypted) 3. Access controls at recipient’s site 4. Time-limited access

Transferring Proprietary Data Securely

Option A: Encrypted ZIP file (fast, simple)

BASH

zip -e proprietary_data.zip proposal_2025.pdf budget_narrative.doc
# Send ZIP via email, password via separate channel (phone call)

Option B: Pomona Box (institutional, recommended)

BASH

# Upload to Box with password + expiration
# Box provides HTTPS/TLS encryption, access controls, audit logging
rclone copy /rhome/<myusername>/data/ pomona_box:research/project_A/

Option C: SFTP via ITS Secure Transfer

BASH

# Request SFTP server access from ITS (its-hpc@pomona.edu)
sftp external_collaborator@secure.pomona.edu
put proprietary_data.tar.gz /drop_zone/

Sharing Restricted Data


Core Rule: Cannot Share Directly

Restricted data cannot be shared with external parties in its original, identifiable form. If you need to share research findings based on restricted data, you must de-identify first (see Episode 12).

Using Institutional Cloud Storage


Box is Pomona’s institutional cloud storage with built-in encryption and access controls.

Box Security: - HTTPS/TLS encryption in transit - AES encryption at rest - Granular access controls (file-level) - Audit logging available - Compliant with FERPA, HIPAA standards

NOT for Restricted data (unless de-identified first).

What NOT to Use

Do NOT use for research data: - Google Drive, Dropbox, iCloud - AWS S3 (unless with specific institutional agreement) - Personal cloud accounts

Why: - No FERPA/HIPAA compliance - Data may be used for training AI models - No enterprise encryption standards - No audit logging

International Collaboration and Export Control


If your research touches cryptography, advanced materials, biotech, or semiconductors, you may be subject to EAR/ITAR export controls.

U.S. persons (U.S. citizens, permanent residents)
    → Can access any data

Non-U.S. persons on approved projects
    → Can access with special license/agreement

Non-approved non-U.S. persons
    → CANNOT access export-controlled research

Before sharing with international collaborators:

  1. Does my research involve novel cryptographic algorithms, advanced materials, semiconductor design, biological agents, or military applications?
  2. If YES: Contact ORSP () for approval
  3. If UNCERTAIN: Consult ORSP anyway – better safe than violating federal law

Publishing Data in Repositories


Repositories suitable for Pomona research:

Repository Suitable For Access
Zenodo General research data Open
OSF Multi-discipline projects Open or restricted
NCBI Biological/medical data Open (de-identified)
GitHub Code and some data Public or private
Figshare Figures, datasets Open
Dryad Data underlying publications Open (curated)

Data Availability Statements

Required by most journals. Examples:

Public data:

"All data are publicly available at Zenodo
(https://doi.org/10.5281/zenodo.XXXXXXX)"

Restricted data:

"Data contain sensitive information (student records protected
under FERPA). De-identified data are available upon request.
Original data are available to qualified researchers under
data use agreement subject to IRB approval."
Challenge

Challenge 11.1: Sharing Decision Tree

For each dataset, decide the appropriate sharing method: 1. Published research paper data 2. Draft grant proposal 3. Student survey responses 4. Preliminary analysis (shared with lab) 5. Export-controlled simulation code

  1. Published research paper data → Public Zenodo deposit
  2. Draft grant proposal → Encrypted transfer with collaboration agreement; Pomona Box with time-limited access
  3. Student survey responses → De-identify + publish; keep encrypted original separate
  4. Preliminary analysis → Sagehen direct access or Pomona Box with group access
  5. Export-controlled code → ORSP approval required; can only share with approved U.S. persons or non-U.S. persons with deemed export license
Key Points
  • Public data can be shared freely with anyone
  • Proprietary data requires collaboration agreement + secure transfer
  • Restricted data cannot be shared directly; must be de-identified first
  • Use institutional Box/OneDrive; avoid personal cloud storage (Google Drive, Dropbox)
  • Export-controlled research requires ORSP approval before international sharing
  • Publish data with DOI for reproducibility and impact
