As medical imaging workflows increasingly shift towards mobility, evaluating proper security controls grows imperative.
For practitioners interacting with sensitive patient images and data, topics like encryption, authentication, and auditing in mobile DICOM viewers surface as priorities.
This piece examines core components attaining HIPAA compliance for mobile DICOM viewing software, enabling protected image analysis via tablet or smartphone.
HIPAA Refresher
Enacted in 1996, the Health Insurance Portability and Accountability Act (HIPAA) instituted safeguards surrounding individual medical information deemed Protected Health Information (PHI).
HIPAA compliance for mobile DICOM viewers centres on the Security Rule’s pillars guarding digital PHI:
- Confidentiality
- Integrity
- Availability
For iOS or Android DICOM viewers managing patient scans and related data, builders must bake in adequate controls upholding regulatory standards.
Essential Aspects of Compliant Mobile DICOM Viewers
Encryption
HIPAA requires “encryption/decryption” when electronically transmitting or storing PHI. This means encoding data, making it unreadable without keys.
Mobile DICOM apps must implement encryption, addressing three facets:
- Data at rest: Image files, metadata stores
- Data in transit: Image transfer/download channels
- Encryption keys: Secure key handling protocols
Proper encryption prevents unauthorized data access even if storage repositories or transmissions get intercepted.
Access Controls
Stringent HIPAA standards mandate access controls strictly limiting PHI availability only to authorized personnel based on necessity.
For mobile DICOM viewer developers, this means building in checks restricting app usage only to verified, licensed practitioners in relevant care contexts.
Tactics like passwords, 2-factor authentication, and contextual access filters provide compliant user control.
Auditing
Meticulous audit trailing also qualifies as required under HIPAA to track PHI access, disclosures, and modifications.
Compliant DICOM apps must institute thorough logging and capturing:
- User login audits
- Image access/download logs
- Annotation changes
- Operational audits
Comprehensive activity logging facilitates security analysis and supports mandatory breach notification policies.
Other Key Areas
Besides core encryption, access rules, and auditing, additional aspects gain relevance when seeking HIPAA-compliant standing for mobile DICOM viewers:
- Transmission security using TLS
- Image and data integrity checks
- Testing security controls against penetration threats and data breaches
- Establishing contingency plans addressing disaster recovery and emergency continuity
- Responsible data disposal and sanitization procedures
- Comprehensive user awareness training surrounding privacy policies
- Contractual documentation ensuring downstream business associates meet compliance standards
Signs of HIPAA Non-Compliance
Common mobile DICOM viewer red flags signaling possible HIPAA violations include:
- Unencrypted image files or data transfers
- Generic, shared, or weak access credentials
- Patient data potentially persisting on devices after usage
- Lack of activity logging
- Unsecured cloud repositories
- Data disposal uncertainty
