    Against the Law: Countering Lawful Abuses of Digital Surveillance
    Created: Jul 12, 2016 | Last Updated: Jul 21, 2016
    Front-line journalists are high-value targets, and their enemies will spare no expense to silence them. Unfortunately, journalists can be betrayed by their own tools. Their smartphones are also the perfect tracking device. Because of the precedent set by the US’s “third-party doctrine,” which holds that metadata on such signals enjoys no meaningful legal protection, governments and powerful political institutions are gaining access to comprehensive records of phone emissions unwittingly broadcast by device owners. This leaves journalists, activists, and rights workers in a position of vulnerability. This work aims to give journalists the tools to know when their smart phones are tracking or disclosing their location when the devices are supposed to be in airplane mode. We propose to accomplish this via direct introspection of signals controlling the phone's radio hardware. The introspection engine will be an open source, user-inspectable and field-verifiable module attached to an existing smart phone that makes no assumptions about the trustability of the phone's operating system.
    簿記と会計の再発明 (確実性を求めて)
    Created: Apr 26, 2016 | Last Updated: May 08, 2016
    複式簿記が現代のような形で導入されたのは 1300年代のことだ。その後、細かいイノベーションはあったものの、価値を追跡して管理する際の根本的な原子単位――会計制度――はいまだにこの700年前の発明に基づいている。今日のコンピュータ、ネットワーク、暗号技術を使えば、21世紀のための会計システムを構築する機会がいまや目の前にある——そのシステムは、簿記の数字の奥を見据えて、機械学習やマルチパーティー計算、アルゴリズム的な表現を使った「価値」の再定義などを活用できる。これを邪魔するものはあるだろうか?
    反マネーロンダリング法と出来の悪い著作権法との類似点と改正の必要性
    Created: Mar 16, 2016 | Last Updated: Mar 16, 2016
    意図的かどうかに関わらず、出来が悪かったり時代遅れだったりする法律や技術標準は、ビットコインやブロックチェーンなどきわめて有望な新技術やネットワークの安全性、プライバシー、有効性を脅かしかねない。公共のためにも法や基準の見直しを積極的に行うべきだ。そして、こうした出来の悪い、または時代遅れの法律に準拠すべく設計された、脆弱で面倒なシステムができるのを防ごうと努力すべきだ。この投稿では、デジタルミレニアム著作権の回避禁止条項、反マネーロンダリング法、KYC法(顧客確認法)、セキュリティ裏口を扱う。
    Why anti-money laundering laws and poorly designed copyright laws are similar and should be revised
    Created: Mar 12, 2016 | Last Updated: Mar 25, 2016
    Abstract: Intentionally or unintentionally, poorly crafted or outdated laws and technical standards threaten to undermine security, privacy and the viability of our most promising new technologies and networks, such as Bitcoin and Blockchain. We should vigilantly be reviewing and revising laws and standards for the public good and working to prevent the creation of fragile and cumbersome systems designed to comply with these poorly crafted or outdated laws. In this post, I discuss the Digital Millennium Copyright Act’s Anti-Circumvention provision, Digital Rights Management, Anti-Money Laundering Law, Know Your Customer Laws and security backdoors.
