Preferential LBS takes a user\u2019s social profile along with their location to generate personalized recommender systems. With the availability of the user\u2019s profile and location history, we often reveal sensitive information to unwanted parties. Hence, providing location privacy to such preferential LBS requests has become crucial. However, the current technologies focus on anonymizing the location through granularity generalization. Such systems, although provides the required privacy, come at the cost of losing accurate recommendations. Hence, in this paper, we propose a novel location privacy-preserving mechanism that provides location privacy through <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>k<\/mml:mi><\/mml:math>-anonymity and provides the most accurate results. Experimental results that focus on mobile users and context-aware LBS requests prove that the proposed method performs superior to the existing methods.<\/jats:p>","DOI":"10.1155\/2020\/8892321","type":"journal-article","created":{"date-parts":[[2020,9,1]],"date-time":"2020-09-01T23:34:30Z","timestamp":1599003270000},"page":"1-13","source":"Crossref","is-referenced-by-count":11,"title":["Privacy-Enhancing Preferential LBS Query for Mobile Social Network Users"],"prefix":"10.1155","volume":"2020","author":[{"given":"Madhuri","family":"Siddula","sequence":"first","affiliation":[{"name":"Computer Science, Georgia State University, Atlanta, Georgia 30302, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingshu","family":"Li","sequence":"additional","affiliation":[{"name":"Computer Science, Georgia State University, Atlanta, Georgia 30302, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiuzhen","family":"Cheng","sequence":"additional","affiliation":[{"name":"Computer Science, George Washington University, Washington, DC 20052, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi","family":"Tian","sequence":"additional","affiliation":[{"name":"Computer Science, George Mason University, Fairfax, VA 22030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6017-975X","authenticated-orcid":true,"given":"Zhipeng","family":"Cai","sequence":"additional","affiliation":[{"name":"Computer Science, Georgia State University, Atlanta, Georgia 30302, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"first-page":"320","volume-title":"The LBS-discrete interactive procedure for multiple-criteria analysis of decision problems","year":"1997","key":"2"},{"first-page":"73","volume-title":"Privacy protection in location-based services: a survey","year":"2018","key":"3"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-017-4284-2"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2822693"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1177\/1550147720912939"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/tdsc.2017.2734664"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TDSC.2019.2949041"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1145\/3318462"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TPDS.2015.2494009"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/tcss.2019.2957795"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2018.2820039"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2015.2469605"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2018.2842470"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2017.06.022"},{"issue":"4","key":"22","first-page":"646","volume":"15","year":"2016","journal-title":"IEEE Transactions on Dependable and Secure Computing"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1007\/s11235-017-0299-y"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1007\/s11036-010-0274-2"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2012.01.009"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/TCSS.2016.2519819"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1109\/TDSC.2016.2613521"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1109\/TPDS.2007.1021"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-48910-X-16"},{"key":"35","doi-asserted-by":"publisher","DOI":"10.1007\/s10618-011-0235-9"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8892321.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8892321.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2020\/8892321.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,1]],"date-time":"2020-09-01T23:34:34Z","timestamp":1599003274000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2020\/8892321\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,9,1]]},"references-count":23,"alternative-id":["8892321","8892321"],"URL":"https:\/\/doi.org\/10.1155\/2020\/8892321","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2020,9,1]]}}}
