Artificial intelligence (AI) models used in dermatopathology need lots of data to learn well. This data includes pictures of skin lesions, dermoscopic images, pathology slides, and important text like patient stories and lab reports. In the United States, the Health Insurance Portability and Accountability Act (HIPAA) sets strict rules on how patient data can be shared. These rules make it hard to gather the large datasets AI requires.
Also, cyberattacks on healthcare organizations happen more often in the US and worldwide. For example, a cyberattack in 2022 targeted a major medical institute in India and exposed personal data of over 30 million people. This shows how patient data security can be weak and is a warning for US healthcare providers.
In addition, photos of skin can be risky for privacy. Even if metadata is removed, pictures can show recognizable features like faces or unique marks. This makes it hard to fully hide the identity of patients in the images. This concern grows when AI needs these images to diagnose complex skin problems.
Collecting skin disease data is further complicated because different places collect data differently. Notes may use different words or formats. Patient groups vary a lot across US states. AI models must learn from all these different types of data. If they do not, the AI might be biased or less accurate for some patients.
Federated learning (FL) helps solve these problems by letting AI train on data stored in many medical centers without moving the data outside. Patient data stays safe on each hospital’s or clinic’s own servers. Only updates on the AI model’s learning are shared between locations.
This way, AI can learn from many patients without exposing private information. It fits well with US privacy laws because the real data never leaves its original place. This lowers the risk of someone outside seeing sensitive data.
Federated learning still faces problems. A review in April 2025 listed some issues, such as:
In dermatopathology, these problems are serious because errors could harm patients. But ongoing research tries to fix these issues so federated learning can meet clinical needs and keep privacy strong.
Multi-Party Privacy Computing (MPPC) works well with federated learning. It lets computers work on encrypted data safely. Even when AI trains together, no one can see the patient data.
MPPC uses methods like Secure Multi-Party Computation (SMPC) and homomorphic encryption. These let AI do math on encrypted datasets, keeping data secret all the time. This helps meet US laws like HIPAA and growing cybersecurity rules.
Using MPPC with federated learning, AI systems in dermatopathology can:
Old AI models in dermatopathology were “unimodal.” They relied on one type of data, like just images. These models need a lot of labeled data and cannot use clinical information beyond pictures.
Newer research shows that “multimodal” AI models work better by using different data types together. These include:
This approach helps AI diagnose more accurately and reliably, even for complex skin problems. For example, by mixing pictures and text, AI learns better about skin diseases and helps doctors make smarter choices.
In the US, providers see many different skin types across populations. Multimodal AI can reduce bias caused by training only on similar data, making diagnostics better for everyone.
US healthcare facilities must follow several laws about patient data. HIPAA is the main federal law protecting health information. It requires providers to keep data safe and private. States also have their own laws adding more rules. For instance, the California Consumer Privacy Act (CCPA) has tough data handling and consumer rights rules.
AI tools that use federated learning and MPPC fit within these laws by limiting how much data moves around and boosting security. Still, hospital leaders and IT teams must keep strong technical and organizational protections.
Key steps to use these AI privacy tools include:
Using AI in dermatopathology is not just about diagnosis. It must work well with doctors’ usual workflows. Practice managers and IT staff in the US use AI to make work easier, save time, and help patient care.
Examples of AI in workflow automation are:
By using AI plus privacy tools, US dermatopathology clinics work better while following privacy laws. These choices let even smaller clinics use AI without big tech or legal issues.
Researchers have studied how AI, dermatopathology, and privacy intersect. Their work guides US healthcare providers.
These studies help US healthcare workers know how to safely and well use AI in dermatopathology.
Medical leaders and IT managers in US dermatopathology can use federated learning and MPPC to adopt AI safely and well. Their roles include:
As AI improves, dermatopathology clinics that manage these tasks well will better serve patients with secure and data-smart care.
Federated learning and multi-party privacy computing address two big problems in AI for dermatopathology in the US: not having enough large datasets and needing strong patient privacy. Medical leaders who understand and use these tools can make good use of AI while following the law and protecting data. Continuing updates to these technologies will help AI play a better role in diagnosis and workflow in dermatopathology, helping doctors and patients alike.
Unimodal AI models rely on a single type of data, typically requiring large volumes of accurately labeled datasets. This restricts their diagnostic capability in dermatology, as they cannot fully utilize the diverse clinical data such as images, patient narratives, and lab reports.
Multimodal AI models integrate various data types including skin lesion images, dermoscopy, pathology images, and text data from patient records. This holistic approach allows the models to learn richer representations, improving diagnostic precision and reliability beyond what unimodal models achieve.
Incorporating text-based data such as patient narratives and lab reports provides contextual information and clinical insights that image data alone cannot capture, thereby enhancing the depth and accuracy of AI diagnostic systems.
Scarcity arises largely from privacy concerns and regulatory limitations preventing widespread sharing or pooling of sensitive dermatological data, hindering the training of robust AI models.
Federated learning allows AI models to be trained across multiple decentralized data sources without transferring sensitive patient data, thus preserving privacy while leveraging a larger, diverse dataset.
The integration of large-scale pre-training multimodal models with federated learning and multi-party privacy computing is proposed to overcome data limitations and privacy issues, leading to high-precision, privacy-preserving dermatological diagnostic tools.
They can support dermatologists by providing more accurate diagnostic suggestions and treatment strategies, improving efficiency, aiding decision-making, and potentially enabling earlier detection of skin diseases.
It involves training AI models on vast, diverse clinical datasets combining multiple data modalities, enabling the models to learn generalized feature representations useful across various dermatological diagnosis tasks.
Because skin conditions are complex and multifaceted, relying on images alone is insufficient. Multimodal AI leverages complementary information from text, images, and other clinical data, resulting in more comprehensive and accurate diagnosis.
Combining federated learning with multimodal AI models is expected to transform healthcare by enabling secure, privacy-preserving AI systems that utilize diverse, distributed patient data to deliver highly accurate diagnostic and treatment recommendations in dermatopathology.
