Prizm: A Wireless Access Point for Proxy-Based Web Lifelogging

Abstract

We present Prizm, a prototype lifelogging device that comprehensively records a user's web activity. Prizm is a wireless access point deployed on a Raspberry Pi that is designed to be a substitute for the user's normal wireless access point. Prizm proxies all HTTP(S) requests from devices connected to it and records all activity it observes. Although this particular design is not entirely novel, there are a few features that are unique to our approach, most notably the physical deployment as a wireless access point. Such a package allows capture of activity from multiple devices, integration with web archiving for preservation, and support for offline operation. This paper describes the design of Prizm, the current status of our project, and future plans.
