[Information Hiding & Multimedia Security Workshop 2015] as a way to balance privacy and usability for online image sharing. The idea is to encrypt a plaintext image into a ciphertext image that has roughly the same thumbnail as well as retaining the original image format. At the same time, TPE allows users to take advantage of much of the functionality of online photo management tools, while still providing some level of privacy against the service provider. In this work we present two new approximate TPE encryption schemes. In our schemes, ciphertexts and plaintexts have perceptually similar, but not identical, thumbnails. Our constructions are the first TPE schemes designed to work well with JPEG compression. In addition, we show that they also have provable security guarantees that characterize precisely what information about the plaintext is leaked by the ciphertext image. We empirically evaluate our schemes according to the similarity of plaintext & ciphertext thumbnails, increase in file size under JPEG compression, preservation of perceptual image hashes, among other aspects. We also show how approximate TPE can be an effective tool to thwart inference attacks by machine-learning image classifiers, which have shown to be effective against other image obfuscation techniques.","PeriodicalId":198787,"journal":{"name":"Proceedings of the 2017 on Multimedia Privacy and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We are pleased to present this newly-established workshop that brings together researchers and practitioners in the fields of multimedia, data privacy, and cybersecurity. MPS 2017 highlights the important intersection of these fields that has been brought about by the emergence and widespread adoption of social media, Internet of Things (IoT), and other ubiquitous computing platforms. Indeed, with the rise of social media, mobile technologies, cloud services, and IoT, massive quantities of multimedia content are created and disseminated as users post updates that include personal information, video and audio data, and other analytical information. Multimedia has arguably expanded well beyond the scope of its original definition. \u0000 \u0000Our call for papers attracted submissions from North America, Central America, Asia, and Europe. We received seven submissions, of which three were selected as Full Papers (42%) and two were accepted as Short Papers after a double-blind review by our program committee. In addition to these presentations, we will feature an invited keynote address and discussion panel: \u0000An NSF View of Multimedia Privacy and Security, Mr. Jeremy Epstein (Deputy Division Director, Computer and Network Systems, National Science Foundation) \u0000Multimedia Security and Privacy with IoT and Social Networks, moderated by Kurt Rohloff and Roger Hallman","PeriodicalId":198787,"journal":{"name":"Proceedings of the 2017 on Multimedia Privacy and Security","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116012488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These wearable IoT devices combined with the extensive use by individu- als of Online Social Networks (OSNs) have raised many security and privacy concerns. Individuals enrich the content of their online posts with their physical performance and attendance at sporting events, without considering the plausible risks that this may result in. This paper aims to examine the potential exposure of users- identity that is caused by information that they share online and personal data that are stored by their tness-trackers. We approach the privacy concerns that arise by building an interactive tool. This tool models online information shared by individuals and elaborates on how they might be exposed to the unwanted leakage of further personal data. The tool also illustrates the privacy risks that arise from information that people expose, which could be exploited by malicious parties such as fraudsters, stalkers and other online and o ine criminals. To understand the level of users-awareness con- cerning their identity exposure when engaging with such devices and online services, we also have conducted a qualitative analysis and present our ndings here.","PeriodicalId":198787,"journal":{"name":"Proceedings of the 2017 on Multimedia Privacy and Security","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131833840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
