    Diff-Privacy: Diffusion-based Face Privacy Protection

    Full text link
    Privacy protection has become a top priority as the proliferation of AI techniques has led to widespread collection and misuse of personal data. Anonymization and visual identity information hiding are two important facial privacy protection tasks that aim to remove identification characteristics from facial images at the human perception level. However, they have a significant difference in that the former aims to prevent the machine from recognizing correctly, while the latter needs to ensure the accuracy of machine recognition. Therefore, it is difficult to train a model to complete these two tasks simultaneously. In this paper, we unify the task of anonymization and visual identity information hiding and propose a novel face privacy protection method based on diffusion models, dubbed Diff-Privacy. Specifically, we train our proposed multi-scale image inversion module (MSI) to obtain a set of SDM format conditional embeddings of the original image. Based on the conditional embeddings, we design corresponding embedding scheduling strategies and construct different energy functions during the denoising process to achieve anonymization and visual identity information hiding. Extensive experiments have been conducted to validate the effectiveness of our proposed framework in protecting facial privacy.Comment: 17page

    Digitaal signage kasutatakse laialdaselt erinevates valdkondades, nagu näiteks transpordisüsteemid, turustusvõimalused, meelelahutus ja teised, et kuvada teavet piltide, videote ja teksti kujul. Nende ressursside usaldusväärsus, vajalike teenuste kättesaadavus ja turvameetmed on selliste süsteemide vastuvõtmisel võtmeroll. Digitaalse märgistussüsteemi tõhus haldamine on teenusepakkujatele keeruline ülesanne. Selle süsteemi rikkeid võib põhjustada mitmeid põhjuseid, nagu näiteks vigased kuvarid, võrgu-, riist- või tarkvaraprobleemid, mis on üsna korduvad. Traditsiooniline protsess sellistest ebaõnnestumistest taastumisel hõlmab sageli tüütuid ja tülikaid diagnoose. Paljudel juhtudel peavad tehnikud kohale füüsiliselt külastama, suurendades seeläbi hoolduskulusid ja taastumisaega.Selles väites pakume lahendust, mis jälgib, diagnoosib ja taandub tuntud tõrgetest, ühendades kuvarid pilvega. Pilvepõhine kaug- ja autonoomne server konfigureerib kaugseadete sisu ja uuendab neid dünaamiliselt. Iga kuva jälgib jooksvat protsessi ja saadab trace’i, logib süstemisse perioodiliselt. Negatiivide puhul analüüsitakse neid serverisse salvestatud logisid, mis optimaalselt kasutavad kohandatud logijuhtimismoodulit. Lisaks näitavad ekraanid ebaõnnestumistega toimetulemiseks enesetäitmise protseduure, kui nad ei suuda pilvega ühendust luua. Kavandatud lahendus viiakse läbi Linuxi süsteemis ja seda hinnatakse serveri kasutuselevõtuga Amazon Web Service (AWS) pilves. Peamisteks tulemusteks on meetodite kogum, mis võimaldavad kaugjuhtimisega kuvariprobleemide lahendamist.Digital signage is widely used in various fields such as transport systems, trading outlets, entertainment, and others, to display information in the form of images, videos, and text. The reliability of these resources, availability of required services and security measures play a key role in the adoption of such systems. Efficient management of the digital signage system is a challenging task to the service providers. There could be many reasons that lead to the malfunctioning of this system such as faulty displays, network, hardware or software failures that are quite repetitive. The traditional process of recovering from such failures often involves tedious and cumbersome diagnosis. In many cases, technicians need to physically visit the site, thereby increasing the maintenance costs and the recovery time. In this thesis, we propose a solution that monitors, diagnoses and recovers from known failures by connecting the displays to a cloud. A cloud-based remote and autonomous server configures the content of remote displays and updates them dynamically. Each display tracks the running process and sends the trace and system logs to the server periodically. These logs, stored at the server optimally using a customized log management module, are analysed for failures. In addition, the displays incorporate self-recovery procedures to deal with failures, when they are unable to create connection to the cloud. The proposed solution is implemented on a Linux system and evaluated by deploying the server on the Amazon Web Service (AWS) cloud. The main result of the thesis is a collection of techniques for resolving the display system failures remotely

    Intentional Infliction of Emotional Distress & The Hulk Hogan Sex Tape: Examining a Forgotten Cause of Action in \u3ci\u3eBollea v. Gawker Media\u3c/i\u3e, the Gap It Reveals in IIED’s Constitutionalization, and A Path Forward for Revenge Porn Victims

    This Article examines Hulk Hogan\u27s successful, yet largely overlooked, cause of action for intentional infliction of emotional distress (IIED) before a Florida jury in 2016 in Bollea v. Gawker Media, LLC. In doing so, the Article explores critical factual differences between Bollea and the U.S. Supreme Court\u27s two decisions constitutionalizing the IIED tort, Hustler Magazine v. Falwell and Snyder v. Phelps. Despite such distinctions, the Article discusses the trial court\u27s instruction to the jury to consider a First Amendment-­based, public-concern defense - one closely akin to that in Snyder - on Hulk Hogan\u27s IIED claim. The Article also proposes a jury instruction on the extreme and outrageous conduct element in IIED that would require jurors to consider the substantive value of the speech in question. Finally, the Article suggests that Hulk Hogan\u27s victory for IIED bodes well for revenge porn victims who pursue civil lawsuits pivoting on this cause of action

    Reframing Libel - Taking All Rights Seriously and where it leads us

    Get PDF
    In preparing this paper, we have returned to first principles and re-evaluated fundamental aspects of libel law, its purposes, its substance, and its processes. Our thinking has been informed by, first, philosophical understandings of democracy and the public sphere and in particular the role of freedom of speech and of the media therein, and secondly, the social psychology of reputation and privacy. By doing this, we are able to ground some of the proposals for reform made previously by Index on Censorship, English PEN, Lord Lester, and others. We do so, however, not through the prism of an over-weaned emphasis on freedom of expression, but rather by triangulating the rights and interests of claimants, defendants, and the wider public. Ultimately, we recommend a coherent set of significant substantive and procedural reforms that if enacted would enhance access to justice and reduce costs for all but the most serious and/or most damaging libels. This involves the recommendation of the introduction of a two-track libel regim
