+title: Cloudflare CAPTCHA Monitoring
+---
+subtitle:
+
+This project should implement a mechanism to track the rate that Cloudflare fronted webpages return CAPTCHAs to Tor users over time.
+
+---
+body:
+
+# Problem
+
+A large number of Tor users report getting hit by infinite CAPTCHA loops when visiting webpages fronted by Cloudflare. This makes them feel punished for using Tor to protect their privacy and prevents them from legitimately accessing websites.
+
+# Proposal
+
+For this project we would like to track in practice how often Cloudflare fronted webpages return CAPTCHAs to Tor clients.
+
+Our proposed approach consists of:
+
+1. Setting up a very simple static webpage to be fronted by Cloudflare
+2. Write a web client to periodically fetch this static webpage via Tor and record how often a CAPTCHA is returned
+3. Record and graph CAPTCHA vs real page rates
+4. Using the pre-existing architecture, run a second client that does not fetch this webpage via Tor. This will allow us to contrast and compare how Cloudflare responds to Tor Browser vs other browsers.
+5. Track and publish these details publicly
+
+There are two interesting metrics to track over time:
+
+- the fraction of exit relays that are getting hit with CAPTCHAs, and
+- the chance that a Tor client, choosing an exit relay in the normal weighted faction, will get hit by a CAPTCHA.
+
+Then there are other interesting patterns to look for:
+
+- Are certain IP addresses punished consistently and others never punished?
+- Is whether you get a CAPTCHA much more probabilistic and transient?
+- Does that pattern change over time?
+
+# Resources
+
+There is pre-existing research by the Berkeley ICSI group which includes these sorts of checks:

+title: Implement new distribution methods for GetTor
+---
+subtitle:
+
+This project should implement a feature to distribute Tor Browser downloads through Telegram or Facebook messenger.
+
+---
+body:
+
+# Problem
+
+Tor Browser ships with a few different anti-censorship tools to allow people free and open access to Internet content. However, some places censor Tor Browser downloads, making it difficult for users to install it in the first place.
+
+#Â Proposal
+
+[GetTor](https://gettor.torproject.org/) is a system for distributing Tor Browser using alternative methods such as email or Twitter to send users authenticated links to Tor Browser binaries.
+
+We are looking to expand the ways in which GetTor distributes Tor Browser binaries to make it easier for people to download and install Tor Browser. This project would consist in implementing a feature in GetTor to distribute Tor Browser downloads through Telegram and/or Facebook messenger.

+title: Onion Tool Box
+---
+subtitle:
+
+Myonion is a developer tool box, providing a command line interface and a GUI to configure and deploy existing services via .onion. The idea behind myonion is to make onion services accessible to developers that might be interested to innovate in the privacy space, building applications that are designed for privacy and security.
+---
+body:
+
+#Â Problem
+
+It is not necessarily difficult to use onion services, but it might be tricky to configure a web service to be offered via .onion so that it doesnâ??t leak sensitive information.
+
+There are detailed [guides](https://riseup.net/en/security/network-security/tor/onionservices-best-practices) available for users that would like to offer a web application via .onion and some tools have been developed to help service operators: discover known misconfiguration or [vulnerabilities](https://onionscan.org/) or deploy an [onion site](https://github.com/alecmuffett/eotk).
+
+Involving a wider developer community can help creating a better image of Tor and onion services, replacing the â??dark netâ?? narrative with the secure and private web one.
+
+Onion services can also be relevant to all those people interested in the â??zero-trustâ?? strategy. The concept behind zero-trust is to adopt strategies and tools to help prevent data breaches by eliminating the concept of trust from an organizationâ??s network architecture, with the principle of never trust, always verify.
+
+Ultimately myonion is about creating a better experience for onion services developers and operators and therefore fostering a more legitimate onion service ecosystem.
+
+#Â Proposal
+
+Myonion is a developer tool box, providing a command line interface and a GUI to configure and deploy existing services via .onion. A minimal prototype for myonion already [exists](https://github.com/hiromipaw/myonion).
+
+Someone that may want to run an onion service can use the myonion wrapper app to start a .onion from their computer and sharea static website or a web application.
+
+Myonion can also be used to deploy the resulting configured app to a defined set of cloud providers.
+
+Myonion provides a way to build and deploy onion ready applications, allowing developers to build and test web applications and easily share them with others, bundling the code and configuration in a lightweight, portable Docker container application that runs the same everywhere.
+
+The experience for developers will be similar to using other industry solutions, like the [Docker desktop app](https://www.docker.com/products/docker-desktop).
+
+Developers using myonion are provided with pre-defined and customizable application templates, with corresponding configuration and a test set, eliminating error-prone manual setup and known onion service configuration mistakes.
+
+The resulting application is therefore deployable via a set of endpoint management tools to known providers. Providing a way to deploy onion services at scale.

+# Background
+
+OONI Explorer is an open data resource on internet censorship around the world. This project is about enriching the OONI Explorer search functionality with the ability to visualize an analysis of metadata pertaining to filtered measurements.
+
+# Proposal
+
+This project is about enriching the OONI Explorer search functionality with the ability to visualize an analysis of metadata pertaining to filtered measurements.
+
+This would involve adding the ability to filter on multiple axis: country, ASN, time range, anomaly, confirmed, failure, domain or input, citizenlab category code.
+
+The results would then be presented in an aggregate form, such as showing:
+
+- The total measurement count
+- The anomaly vs total ratio
+- Confirmed vs total
+- Failure vs total
+
+These results could then be presented as a table or some other charts, such as a heatmat.
+
+Some other more detailed, drill-down views could also be implemented.
+
+A potential applicant should also have some prior design experience

+title: OONI Probe network experiments
+---
+subtitle:
+
+OONI Probe is a free software project that aims to uncover internet censorship around the world. As part of this project you would be working on researching and developing new OONI Probe network experiments.
+
+---
+body:
+
+# Background
+
+The Open Observatory of Network Interference (OONI) is a free software project which aims to empower decentralized efforts in increasing transparency of internet censorship around the world.
+
+We develop free and open source software, called OONI Probe, that users can run to measure:
+
+- Blocking of websites;
+- Blocking of instant messaging apps (WhatsApp, Facebook Messenger and Telegram);
+- Blocking of censorship circumvention tools (such as Tor);
+- Presence of systems (middleboxes) in your network that might be responsible for censorship and/or surveillance;
+- Speed and performance of your network.
+
+By running OONI Probe, users can collect data that can potentially serve as evidence of internet censorship since it shows how, when, where, and by whom it is implemented.
+
+# Proposal
+
+*Prerequisites:* Knowledge of network programming
+
+As part of this project you would be working on researching and developing new OONI Probe network experiments. These experiments would be integrated inside of probe-engine and could eventually make their way into the OONI Probe desktop client.
+
+The GSoC project is only about researching and implementing a working test in probe-engine, not the UI and client integration of the test.

+title: Privacy aware geo lookup
+---
+subtitle:
+
+The idea for this project is to research a way to do a GPS based location lookup which resolves the location of the user to a granularity which is useful for qualifying measurements, but that doesnâ??t compromise users safety and privacy.
+
+---
+body:
+
+# Problem
+
+When looking at OONI Probe measurements we often face a challenge in properly understanding what country (or more granular location) they are telling us things about.
+
+Often times the location information (since it's based on geoip) is inaccurate, because the underlying GeoIP database we used was old.
+
+On the other hand we also have a responsibility to protect user privacy to the extent that it's possible and therefore we don't collect IPs or store location information that is more granular than country level.
+
+# Proposal
+*Prerequisites:* familiarity with Android development and aptitude for research
+
+The idea for this project is to research a way to do a GPS based location lookup which resolves the location of the user to a granularity which is useful for qualifying measurements, but that doesnâ??t compromise users safety and privacy.

+title: Privacy Friendly Web
+---
+subtitle:
+
+The scope of this project is creating a open-source community-driven browsable list of patterns and release a css/js framework that web developers can extend and use in their work.
+---
+body:
+
+# Problem
+
+Security concerned web users take conscious steps to limit the amount of data they share with the websites visited and third party services.
+
+There are a number of security enhancing tools available. Some come in the form of browser extensions and javascript blockers, others are full fledged web browsers designed with providing extra security to their users.
+
+One of these is the Tor Browser. The Tor Browser was designed to provide privacy while surfing the web and defend users against both network and local forensic adversaries. There are two main categories of requirements that have been considered: Security Requirements, and Privacy Requirements.
+
+Security Requirements are the minimum properties in order for a browser to be able to support Tor and similar privacy proxies safely. Privacy requirements are primarily concerned with reducing linkability: the ability for a user's activity on one site to be linked with their activity on another site without their knowledge or explicit consent.
+
+# Proposal
+
+Websites can work seamlessly with the Tor Browser and other privacy enhancing browsers and tools if they adopt a series of respectful and ethical patterns.
+
+The Tor Browser is in fact, based on Mozilla's Extended Support Release (ESR) Firefox branch. We have a series of patches against this browser to enhance privacy and security. Browser behavior is additionally augmented through the Torbutton extension, and we also change a number of Firefox preferences from their defaults.
+
+The Tor Project has developed over the years a set of web development guidelines that allow websites to work with security enhanced browsers without causing any or minimal functionality destruption to their users. These guidelines have been shaped in an internal styleguide that has been adopted across all torproject.org websites.
+
+We are now formalizing these web development patterns and some security concerns that need to be considered when developing websites for users surfing the web with security enhanced browsers and tools. The scope of this project is creating a open-source community-driven browsable list of patterns and release a css/js framework that web developers can extend and use in their work.

+title: Implementing Salmon as a bridge distribution mechanism
+---
+subtitle:
+
+This project entails implementing Salmon, a bridge distribution mechanism that partitions and distributes bridges using reputation to give well-behaved users access to "better" bridges and add a penalty when their bridges get censored.
+
+---
+body:
+
+# Problem
+
+Bridges are Tor relays that are not publicly listed and therefore allow access to the Tor network in places where access to the public Tor relays, and therefore access to the Tor network, is blocked. Many users rely on bridges, or anti-censorship proxies, to connect to the Tor network. However, when censors learn this information, the bridges quickly become blocked and can no longer be used. We need a way of distributing bridge information to users so that they are able to connect without these bridges being discovered by the censors.
+
+# Proposal
+
+Our goal is to distribute bridges to users in censored regions when they need them, while also limiting the amount of bridge information that is leaked to censors. This project entails implementing Salmon, a bridge distribution mechanism that partitions and distributes bridges using reputation to give well-behaved users access to "better" bridges and add a penalty when their bridges get censored.

+subtitle:
+
+This project entails implementing a Snowflake proxy app that will run on Android and relay a user's Tor traffic to the Tor network in the background.
+
+---
+body:
+
+# Background
+
+[Snowflake](https://snowflake.torproject.org/) is a circumvention system in which volunteers can run proxies to help users connect to the Tor network. Users make WebRTC connections to the proxies, who then relay this data to a Snowflake bridge and then on to the Tor network. The advantage of using WebRTC is that Snowflake proxies can frequently change IP address or operate behind a NAT. At the moment, we have implemented the Snowflake proxy code as a web extension or a web badge, but we have not yet implemented a proxy that will run smoothly on Android.
+
+# Proposal
+
+This project entails implementing a Snowflake proxy app that will run on Android and relay a user's Tor traffic to the Tor network in the background. There is an implementation component as well as an exploration and testing component while we figure out how to achieve good performance from a background application without using too much of the volunteer proxy's data or resources.

+body:
+
+The Tor Project will be improving tor relay IPv6 support in 2020.
+
+Students may choose to focus on:
+ * designing and implementing tor relay IPv6 features,
+ * tor relay IPv6 testing, or
+ * diagnosing and fixing bugs in tor's IPv6 code.
+
+## Prerequisites
+
+* Network configuration skills
+* Basic understanding of IPv4 and IPv6
+
+Recommended:
+
+* Experience testing network software
+* Experience running Internet-connected servers
+

+
+This project would implement a notification system for relay operators to alert them when the state of their relay has changed. This is the most efficient way to achieve and maintain a healthy Tor network on the long run.

+
+# Problem
+
+If a relay disappears today, it is unlikely that anyone will notice or even send an email to the operator.
+
+The entire Tor network would benefit from a "Tor Weather" service to notify relay and bridge operators when the state of their relays has changed. This has a number of benefits, including:
+
+- increasing the likelihood that relay operators notice problems and actually mitigate them.
+- showing relay operators that someone actually cares if their relays go down or become outdated or have another problems
+- giving relay operators information about best-practices, e.g not running outdated versions, fixing their DNs, etc...
+
+Right now, there is very little direct feedback given to relay operators. This can mean that operators become discouraged and stop running relays.
+
+# Proposal
+
+This project would involve the implementation of an email notification service that relay operators can subscribe to and choose which notifications they want to receive about their relay.
+
+This project already existed and was known as "Tor Weather". It was unfortunately [discontinued](https://lists.torproject.org/pipermail/tor-relays/2016-April/009009.html) due to lack of maintenance and resources to keep the project alive. However, we think that this is still a great idea and the most efficient way to achieve and maintain a healthy Tor network on the long run. The resulting service should conform to our current [styleguide](https://styleguide.torproject.org/).
+
+This notification service should support subscribing via single relay fingerprint or MyFamily groups. Additionally, it should not need any subscription change if a new relay gets added to the family. As this service would store email addresses of potential tor relay operators, they should be kept private and safeguarded. However, a passive observer can collect them by watching outbound email traffic if no TLS is used. As such, this service should suggest using a dedicated email address for this service.
+
+Once a basic email notification service is implemented, these are some ideas for potential notification types that could be implemented within it:
+- Email me when my node is down - Here we should decide how long before we send a notification?
+- Email me when my relay is affected by a security vulnerability
+- Email me when my relay runs an end-of-life version of tor
+- Email me when my relay runs an outdated tor version
+- Email me when my exit relay fails to resolve hostnames (DNS failure)
+- Email me when my relay looses the stable/guard/exit flag
+- Email me when my MyFamily configuration is broken
+- Email me when you detect issues with my relay
+- Email me with suggestions for configuration improvements for my relay
+- Email me when my relay is on the top 20/50/100 relays list
+- Email me with monthly/quarterly status information, e.g what is my position in the overall relay list, how much traffic did my relay do during the last month, etc...
+- Email me about new relay requirements
+- Email me about tor relay operator events
+
+For each notification implemented, there should be a corresponding specification written to describe the meaning of each notification type.
