 Protecting privacy and confidentiality is critical for large-scale data analysis and machine learning. Analytics Zoo ***PPML*** combines various low level hardware and software security technologies (e.g., Intel SGX, LibOS such as Graphene and Occlum, Federated Learning, etc.), so that users can continue to apply standard Big Data and AI technologies (such as Apache Spark, Apache Flink, Tensorflow, PyTorch, etc.) without sacrificing privacy.
 
 ## 1.1 PPML for Big Data AI
-Analytics Zoo provides a distributed PPML platform for protecting the *end-to-end Big Data AI pipeline* (from data ingestion, data analysis, all the way to machine learning and deep learning). In particular, it extends the single-node [Trusted Execution Environment](https://en.wikipedia.org/wiki/Trusted_execution_environment) to provide a *Trusted Cluster Environment*, so as to run unmodified Big Data analysis and ML/DL programs in a secure fashion on (private or public) cloud:

 With the trusted Big Data analytics and ML/DL support, users can run standard Spark data analysis (such as Spark SQL, Dataframe, MLlib, etc.) and distributed deep learning (using BigDL) in a secure and trusted fashion.
