As organizations train LLMs on sensitive data, privacy risks are a major concern. Without safeguards, personal information can be exposed, leading to compliance and trust issues. The solution? De-identification. Common techniques include: 🔑 Tokenization: Replaces sensitive data with non-sensitive placeholders. 🔒 Data Masking: Obscures parts of the data. 🔗 Hashing: Converts data to fixed-length strings. 📊 Generalization: Replaces data with broader categories. 🎛️ Differential Privacy: Adds noise to protect individual info. Which approach is right for you depends on the specific use case and requirements around preserving data utility and format. Skyflow can handle the entire lifecycle of de-identifying of data sets, from ingestion to de-identifying disparate data across audio, text, files, images and placing them back into a data repository before it’s sent for training or fine tuning the model. Recently, we've been working with a leading healthcare company, building a privacy-safe LLM by applying these techniques. The solution keeps the sensitive data secure and private without compromising model integrity, ensuring both compliance and protection of sensitive information.
