2014年3月,美国工程教育学会(American Society of Engineering Education)展示了大数据中的加密搜索和集群形成。麻省理工学院计算机科学和人工智能实验室的Gautam Siwach和UNH研究小组的Amir Esmailpour致力于解决大数据的挑战,他们研究了大数据的关键特征,如集群的形成及其相互关联。他们通过提供技术中的原始定义和实时示例,重点关注大数据的安全性,以及该术语在云接口以加密形式存在不同类型数据的方向。此外,他们还提出了一种识别编码技术的方法,以加快对加密文本的搜索,从而增强大数据的安全性。<ref>{{cite conference |url=http://asee-ne.org/proceedings/2014/Student%20Papers/210.pdf |title=Encrypted Search & Cluster Formation in Big Data |last1=Siwach |first1=Gautam |last2=Esmailpour |first2=Amir |date=March 2014 |conference=ASEE 2014 Zone I Conference |conference-url=http://ubconferences.org/ |location=[[University of Bridgeport]], [[Bridgeport, Connecticut|Bridgeport]], Connecticut, US |access-date=26 July 2014 |archive-url=https://web.archive.org/web/20140809045242/http://asee-ne.org/proceedings/2014/Student%20Papers/210.pdf |archive-date=9 August 2014 |url-status=dead }}</ref>
