Funf 是一个可扩展的传感和数据处理框架，主要用户移动设备，由麻省理工学院的媒体实验室开发。其核心概念是开源、可重用的功能集、支持收集上传和配置各种不同数据类型。

主要特点：

• Remote configuration.
• Many built-in data “probes”.
• Automatic or manual data upload.
• Delay tolerant implementation – When internet connection is not available, caches data locally until server connection is restored.
• One-way hashing and encryption for sensitive data: Does not save any textual data or phone numbers in human-readable format.
• Encryption of locally stored database files.
• 3rd-party data input API allowing any app to leverage the Funf framework for collecting and storing arbitrary app data.
• Modular probe architecture allows for adding core data probes and modifying existing probe behavior.
• Basic survey system for manual data collection.
• Various optimizations for prolongig battery life and dealing with everyday use-cases (e.g. when SD card is not available because user is copying music files to it)
• Field proven – Deployed for over 15 months with over 100 users in an MIT living laboratory experiment.
