Games can be ideal tools to help educate the public on any subject matter. The task is to create an augmented reality game using a “learn by doing” method. The game will introduce players to augmented reality, and thus demonstrate how this technology can be combined with the world around them. The Tango, Unity and Vuforia are the tools to be used for development. The game itself will be a coin collecting game that changes dynamically to the world around the player. 3 List of Figures Figure 1: Project Tango Device 1 Figure 2: Ceiling with an array of markers 9 Figure 3: floor with an array of markers point 10 Figure 4: Vuforia stock image used for image recognition 11 Figure 5: Initial System Design 15 Figure 6: Final System design 15 Figure 7: Unity view of game 17 4 List of Tables Table 1: Evaluation Criteria 8-9 Table 2: Example of code for coin collection 11 Table 3: Research Questions 12 5 Project Overview Background Google developed the Tango to enable users to take advantage of the physical world around them.

  • Accountable Privacy for Decentralized Anonymous Payments
    Accountable Privacy for Decentralized Anonymous Payments Christina Garman, Matthew Green, and Ian Miers Johns Hopkins University fcgarman, mgreen, [email protected] Abstract. Decentralized ledger-based currencies such as Bitcoin provide a means to construct payment systems without requiring a trusted bank. Removing this trust assumption comes at the significant cost of transac- tion privacy. A number of academic works have sought to improve the privacy offered by ledger-based currencies using anonymous electronic cash (e-cash) techniques. Unfortunately, this strong degree of privacy creates new regulatory concerns, since the new private transactions can- not be subject to the same controls used to prevent individuals from conducting illegal transactions such as money laundering. We propose an initial approach to addressing this issue by adding privacy preserving policy-enforcement mechanisms that guarantee regulatory compliance, allow selective user tracing, and admit tracing of tainted coins (e.g., ransom payments). To accomplish this new functionality we also provide improved definitions for Zerocash and, of independent interest, an efficient construction for simulation sound zk-SNARKs. 1 Introduction The success of decentralized currencies like Bitcoin has led to renewed interest in anonymous electronic cash both in academia [2, 9, 20] and in practice (including Coinjoin, CryptoNote, and DarkWallet). It has also highlighted new problems related to trust, privacy and regulatory compliance. In modern electronic payment systems, users must trust that their bank is not tampering with the system (e.g., by \forging" extra currency), that no party is abusing the privacy of users' transactions, and simultaneously, that other users are not using the system to engage in money laundering or extortion.
