Indexing Encrypted Data Using Bloom Filters

H.2215 (Ferrer)
Claude Warren
Bloom filters are a probabilistic data structure that tell us where things are not. They also utilize one way hash functions to build a probabilistic representation of an object. This talk will address how this structure can be used to provide an index into encrypted data that can be made publicly available with minimal risk.

Talk will cover how bloom filters are constructed, the Flat Bloofi indexing implementation and how to take the properties to be indexed and create Bloom filters, and then how to associate the bloom filter with the encrypted object in the index.

The result is an extremely fast index that can retrieve data items containing partial keys.

After this talk participants will be able to provide search capabilities across a collection of encrypted objects.

Code examples will be provided.

For as long as human society has existed, humans have been unable to trust each other. For millennia, we relied on middlemen to establish business or legal relationships. With the advent of Web2.0, we also relayed the establishment of personal connections, and the system has turned against us. The middlemen abuse our needs and their power and we find ourselves chained to convenience at the expense of our own thoughts, our own privacy. Web3 is a radical new frontier ready to turn the status quo ...

While actual browsers expose their internals through an API and limit access to the host system, Next doesn't, allowing for infinite extensibility and inviting the users to program their web browser. On top of that, it doesn't tie itself to a particular platform (we currently provide bindings to WebKit and WebEngine) and allows for live code reloads, thanks to the Common Lisp language, about which we'll share our experience too.

Please note that this talk will now be given by Michal Čihař instead of Václav Zbránek. You will learn how to localize your project easily with little effort, open-source way. No repetitive work, no manual work with translation files anymore. Weblate is unique for its tight integration to VCS. Set it up once and start engaging the community of translators. More languages translated means more happy users of your software. Be like openSUSE, Fedora, and many more, and speak your users' ...
