However, most of these servers are hackable or untrustworthy, which makes their computation questionable. Therefore, there is need for clients to validate the correctness of the results of their outsourced computations and ensure that servers learn nothing about their clients other than the outputs of their computation. In this work, an efficient privacy preservation validation approach is developed which allows clients to store and outsource their computations to servers in a semi-honest model such that servers' computational results could be validated by clients without re-computing the computation. This article employs a morphism approach for the client to efficiently perform the proof of correctness of its outsourced computation without re-computing the whole computation. A traceable pseudonym is employed by clients to enforce anonymity.<\/p>","DOI":"10.4018\/ijcac.2019040105","type":"journal-article","created":{"date-parts":[[2019,3,21]],"date-time":"2019-03-21T13:19:33Z","timestamp":1553174373000},"page":"79-98","source":"Crossref","is-referenced-by-count":18,"title":["An Efficient Privacy-preserving Approach for Secure Verifiable Outsourced Computing on Untrusted Platforms"],"prefix":"10.4018","volume":"9","author":[{"given":"Oladayo Olufemi","family":"Olakanmi","sequence":"first","affiliation":[{"name":"University of Ibadan, Ibadan, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adedamola","family":"Dada","sequence":"additional","affiliation":[{"name":"University of Ibadan, Ibadan, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJCAC.2019040105-0","doi-asserted-by":"crossref","first-page":"401","DOI":"10.1145\/2590296.2590343","article-title":"Outsourceable two-party privacy-preserving biometric authentication.","author":"H.Chun","year":"2014","journal-title":"Proceedings of the 9th ACM symposium on Information, computer and communications security"},{"key":"IJCAC.2019040105-1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2018.06.003"},{"key":"IJCAC.2019040105-2","author":"B.Gupta","journal-title":"Computer and cyber security principles algorithm applications and perspectives"},{"key":"IJCAC.2019040105-3","doi-asserted-by":"publisher","DOI":"10.4018\/978-1-5225-0105-3"},{"issue":"7","key":"IJCAC.2019040105-4","doi-asserted-by":"crossref","first-page":"9203","DOI":"10.1007\/s11042-017-5301-x","article-title":"Advances in security and privacy of multimedia big data in mobile and cloud computing.","volume":"77","author":"B.
