Presentation of my bachelor's thesis at ETH Zurich BitThief is a free loading BitTorrent client, that is, it downloads from the swarm without uploading. As a part of this project, following goals were achieved. - Integrate meta-search engine - No hard-coding i.e. make system fully user configurable - Allow users to filter results using query strings - Show latest torrents on user's chosen categories such as movies, TV, etc.

1. BitThief New UX
Project Supervisors:
- Michael König
- Prof. Roger Wattenhofer

Department of Computer Science,
University of Toronto

2. Scenario 1

3. SCENARIO 2

4. SCENARIO 3
•
Interested only in movie torrents by “YIFY”
•
Interested only in torrents with seeders greater than
50

5. GOAL
Build and integrate a system into BitThief that
•
Performs meta-search on various sites like
Torrentz
•
Has nothing “hard-coded” i.e. is fully configurable
•
Allows the user to filter results
•
Shows user the latest torrents in their chosen
categories (e.g. movies, tv, music, etc.)

6. GOAL #1: META-SEARCH
•
Torrent website URL (e.g. https://thepiratebay.org)
•
Torrent Query URL Format

7. Torrent Query URL Format
•
Replace the search term with “<query>”
http://extratorrent.cc/search/?page=1&search=star+wars
http://extratorrent.cc/search/?page=1&search=<query>
•
Replace the page number with “<index>”
http://extratorrent.cc/search/?page=<index>&search=<query>

8. GOAL #2: FULLY CONFIGURABLE

9. GOAL #3: FILTER RESULTS
For this, we need
•
Information about the torrent like
•
Seeders
•
Size
•
Title
...
•
Query Strings

10. XPaths and Regex
Example…
Name: Uploaded
Value: //*[@id='details']/dl[@class='col2']/dd[1]/text()
Regex: (?<Year>d+)-(?<Month>d+)-(?<Day>d+)

11. Query Strings
•
Title contains “YIFY”
•
Uploaded:Year == 2016 AND (Seeders > 100 OR Size < 2)
•
Released after “03 December 2015”

12. SEARCH

13. GOAL #4: SHOW LATEST TORRENTS

14. Torrent Categories
•
Name (e.g. TV)
•
URL (e.g. https://kat.cr/tv/)
•
Query String (e.g. Title contains “game of thrones”)

15. Profiles

16. POWER USER
•
Xpaths
•
Regular Expressions
•
Queries
That’s where the fun lies…..

17. Create the hype!
Share configurations with friends
•
Copy to clipboard
•
Create from clipboard

18. FUTURE WORK
•
Make debugging better
•
IMDB, etc. API Integration
•
Obviously, better GUI
