  • What is Privacy? 2022-03 Phil Windley

    The International Association of Privacy Professionals (IAPP) defines four classes of privacy:

    • Bodily Privacy—The protection of a person’s physical being and any invasion thereof. This includes practices like genetic testing, drug testing, or body cavity searches.
    • Communications Privacy—The protection of the means of correspondence, including postal mail, telephone conversations, electronic mail, and other forms of communication.
    • Information Privacy—The claim of individuals, groups, or organizations to determine for themselves when, how, and to what extent information about them is communicated to others.
    • Territorial Privacy—Placing limitations on the ability of others to intrude into an individual’s environment. Environment can be more than just the home, including workplaces, vehicles, and public spaces. Intrusions of territorial privacy can include video surveillance or ID checks.

  • Privacy, Authenticity, and Confidentiality 2022-03 Phil Windley

    Authenticity allows parties to a conversation to know to whom they are talking. Confidentiality ensures that the content of the conversation is protected from others. These three create a tradespace because you can’t achieve all three at the same time.

  • Identity is evolving — but the battle for privacy has only just begun 2022-03-10 Avast

    But with challenges in the offing and platforms preparing to do battle, we must all support initiatives that support privacy and security, as well as the services that will bolster it. We must expect better and support the solutions that help us do better. That’s the only way to create a future where privacy and security are at the core of our collective digital experiences.

  • The new age of privacy 2021-01-06 Ben Werdmuller

    Privacy is a human right. Surveillance has a chilling effect on free speech and freedom of association, which we consider to be fundamental tenets of democracy. Sure, you can make a bunch of money by learning everything you can about an individual and selling access to their attention. But not everything that is profitable should be permissible.

  • How the cookie poisoned the Web 2021-05-14 Doc Searls

    Have you wondered why you have no more privacy on the Web than what other parties grant you (which is none at all), and that you can only opt in or out of choices that others provide—while the only controls you have over your privacy are to skulk around like a criminal (thank you, Edward Snowden and Russell Brand, for that analogy) or to stay offline completely?

    “Zero party data is that which a customer intentionally and proactively shares with a brand. It can include preference center data, purchase intentions, personal context, and how the individual wants the brand to recognize her.”

  • Verifiable credentials are key to the future of online privacy 2021-07-26 Helpnet

    they offer a few advantages that we don’t get with paper records. Whereas a physical document (let’s say, a vaccine card) can be forged and passed off as authentic, the security mechanisms behind a verifiable credential means that it can never be tampered with and that anyone shown the credential will be able to immediately verify who issued it and to whom it was issued. 2021-06-08

  • Identity and Privacy: Past, Present, and Digital 2018-09-21 Brenda K. Leong SSI Meetup

    Underlying this conversation is the concept of privacy. Is it a fundamental right? What does it mean? Who gets to decide which conveniences are worth the tradeoffs they require? Are the protections for personal data offered by policy and law sufficient, or should technical and security protections be required? Are some systems simply too high-risk to implement regardless of perceived benefits? To answer those questions, it’s important to understand the technologies at work – biometrics such as fingerprints and facial recognition offer greater reliability, security and certainty, but raise fears of “permanent” breach if the personal data is compromised. These systems offer accessibility at scale that can be updated throughout a lifetime in a way that password-based accounts cannot equal. But fair access to all, protections of personal data, and most importantly, legal, policy, and technical protections against discrimination and abuse are critical to ensuring these and related technologies are not simply used to restrict personal freedom, or target groups and other populations. Brenda covers how these and other aspects of the modern concept of “digital identity” are being approached in different ways, and what some of the benefits and risks are for the future.

  • Zero-Knowledge Proofs: Privacy-Preserving Digital Identity 2018-10-12 Clare Nelson SSI Meetup

    Clare will explain why ZKPs are so powerful, and why they are building blocks for a range of applications including privacy-preserving cryptocurrency such as Zcash, Ethereum, Artificial Intelligence, and older versions of Trusted Platform Modules (TPMs). The presentation includes many backup slides for future learning and researching, including four slides of references.

  • Letter to Attorney General Becerra Re: FinCen Proposed Rule Privacy concerns 2021-02-23 Ally Medina BlockAdvocacy

    Our concerns with the consumer privacy implications of this proposed rule are twofold:

    First, the proposed rule’s requirement that MSB’s collect identifying information associated with wallet addresses will create reporting that extends well beyond the intent of the rule or the transaction.

  • Why Privacy by (Re)Design Better Defines Responsibility for Privacy 2021-09 Anonyome

    The self-sovereign internet underscores a tension between those who desire perfect oversight of society and those who desire perfect privacy. In this post, I explore a method for conditional legibility of private communications.

  • Agency By Design (Privacy is not Enough) 2021-05-06 Adrian Gropper

    I’m not a fan of Privacy by Design.
    In the industry are only concerned about compliance, very rarely talk about Human Agency
    Privacy by Default is the opposite in some sense to privacy by design
    The problem is that It conflict with community in many cases. (e.g. social credit score)
    Cultural differences (EU accepts better centralization than US)
    Delegation and agency are one the same thing
    Agency is a much bigger thing and delegation is a mechanism that supports it
    I want my fiduciaries to know as much as possible of me (e.g. my doctor, my lawyer)
    Model Agency as hierarchy and delegation is the mean to have it.

Privacy Violations

  • Businesses need to ‘mind the trust gap’ so users don’t need to sacrifice privacy, MEF Global Consumer Trust Survey finds 2021-05-20 Digi.me
    • Users sacrifice privacy and security for access to valued services
    • Smartphone users begin to sense improvement in the mobile environment
    • More and more users take protective steps, but remain exposed to harm
    • Protective actions do not necessarily drive confidence
    • Cost, knowledge and perceived complexity are key barriers
    • Transparency and control are key values for users

  • John Oliver on Surveillance Capitalism 2022-04 Phil Windley

    In researching this story, we realized that there is any number of perfectly legal bits of f—kery that we could engage in. We could, for example, use data brokers to go phishing for members of congress, by creating a demographic group consisting of men, age 45 and up, in a 5-mile radius of the U.S. Capitol, who had previously visited sites regarding or searched for terms including divorce, massage, hair loss and mid-life crisis.

  • Links Between Privacy and Disinformation: Julia Angwin 2021-07

    Privacy, as we know, is a complex topic. When it converges with technology, it becomes more complicated.  One aspect of this complexity is where privacy fits in with disinformation—false or misleading information spread intentionally to confuse or manipulate people.
