Barcelona Initiative for Technological Sovereignty (BITS) seeks to stimulate a global debate on the changes taking place in the meaning of sovereignty, and to explore the ways in which the different types of sovereignty - that of citizens, cities, nations and regions - match with the global technologies. Paying special attention to the political effects of technological change, BITS explores how the emergence of technological platforms and data extractivism is transforming government, work, property and access to the basic means for survival such as water, food, housing and energy.

British Columbia First Nations’ Data Governance Initiative

British Columbia First Nations’ Data Governance Initiative (BCFNDGI) is an initiative to migrate to a model of development of welfare that is self-governing, community driven, and nation based. The autonomy to define community wellness and the right of First Nations communities to own, control, access, and possess information about their peoples are fundamental if they are to achieve self-determination and preserve and develop their culture. BCFNDGI is a comprehensive and integrated approach to addressing complicated and long-standing socio-economic and cultural issues.


Since time immemorial, it was believed that an IP address and HTTP cookies were the only reliable digital fingerprint to affect online privacy and the identity of the web browser. After some time, they sought other ways to increase their ability to track the activity of surfers as users in order to identify them and to separate the wheat from the chaff. As a result, they began to collect user-sensitive information. Currently, the situation is quite daunting. Modern browsers have not been made to ensure privacy on the web. The developers of anonymity networks such as TOR cannot edit the source code of browsers in order to mitigate this surveillance, which is why using TOR does not guarantee privacy. is a project about web browser fingerprinting. It provides a gallery of tools that allow you to check the security of your web browser and verify the information that you surrender when you surf the web.

  • Biometrics

    Biometric systems are designed to identify people or to verify their identity using their physical characteristics or their intrinsic behaviour. These include digital fingerprints, the recognition of fingerprints, the palm of the hand or the face, voice, fingerprint or DNA, among others.

  • Anonymity

    The anonymisation of online life refers to our being able to say things online that we do not want to be connected to our real identity, whether for political or economic reasons or due to harassment, or even a threat to our own life. It can be useful in multiple scenarios: people working against repressive governments in defence of human rights, or to create an anonymous identity so that children can explore Internet freely, or to rebuild lives that have been derailed by abuses in the past.

  • Know your rights

    Know your rights is a campaign to allow US citizens to know their rights regarding their data that is stored in electronic devices.

  • Mandatory Data Retention

    Mandatory Data Retention is a line of work of the EFF that warns about data retention by Internet service providers (ISPS), in other words, the companies that provide our connection to the Internet and those our data pass through during the provision of such services.

  • Artificial Intelligence and Machine Learning

    Rapid progress has been made in the field of automatic learning and neural networks during the course of the past decade, and certain issues that have arisen are of vital importance:

    • What happens with the data sets that are collected by private technology companies?
    • What rules, if any, should constrain the use of automatic learning methods when it comes to technologies for large scale surveillance carried out by intelligence agencies?
    • When algorithms, including automatic learning and artificial intelligence systems, make decisions that affect human lives, from the most mundane issues such as a different price to much more profound ones, what standards of transparency, openness and accountability should be applied to these decisions? If the decisions are wrong, who is legally responsible?
    • How do we prevent the biased results that automatic learning systems can produce, or other forms of profile creation?
  • Border searches

    Boarder Searches warns about the practice of collecting data from social networks or electronic devices that may occur at borders - including airports - in the United States of America.


    The Communications Act refers to the CALEA Act (Communications Assistance for Law Enforcement Act, 1994) which required telephone companies to modify their network architecture to facilitate the legally permitted tapping of phone calls. In 2005, the FCC (Federal Communications Commission) extended this Act to Internet service providers, (ISPS) and voice over IP (VoIP, Internet telephony) services. Years later, the FBI tried to extend it to any software that would allow online communication. Criticism stopped it, but it has come up again several times since then.

  • Cell tracking

    Cell tracking warns about last-generation mobile phone location logs which make it possible to obtain certain data that otherwise could not be obtained without a court order.

  • Do Not Track

    Do Not Track is a guide for users of online services. Social networking services, analytical companies or advertising companies tend to record their behaviour, but this guide helps such users keep their behaviour unrecorded.

  • Encrypting the web

    Encrypt the Web warns about web services that do not use the HTTPS protocol that allows encrypted communications, which is why they have launched the HTTPS Everywhere campaign.

  • Cyber Security Legislation

    Each year, the US Congress receives several draft bills on cyber security (Cyber Security Legislation). In 2014, the Cyber Intelligence Sharing and Protection Act (CISPA) reached Congress and the Cybersecurity Information Sharing Act (CISA) reached the Senate. Their purpose was to give companies legal immunity to share more information between government and private companies.


  • certbot

  • Privacy Badger

    Privacy Badger is an extension for browsers that blocks advertisers and other third-party trackers, stopping them from knowing such things as where you surf to and what pages you visit on the web. If an advertiser seems to be tracking you through various websites without your permission, Privacy Badger automatically blocks the advertiser from loading more content on your web browser. As far as the advertiser is concerned, it’s as if you had suddenly disappeared.

  • Panopticlick

    Panopticlick warns about the status of your browser with respect to the ability of third parties to track your surfing activity without your consent. The tool analyses the browser, and its extensions, and displays the results in five points:

    • Does the browser block ad cookie tracking?
    • Does the browser block invisible trackers?
    • Are trackers that are included in the list of “acceptable advertising” blocked?
    • Does the browser block third parties that promise not to track?
    • Does the browser protect your digital fingerprint?
  • HTTPS Everywhere

    HTTPS Everywhere is a browser extension, available for Firefox, Chrome and Opera, that encrypts your communications with web sites, allowing you to browse more securely. The project arose from the collaboration of EFF with the TOR project.

  • Decoding 702

    A campaign against email decoding which the US government facilitated by passing Section 702.
