A two-dimensional code spatiotemporal modeling method is proposed in this paper. We apply the two-dimensional code as an information carrier to store object's characteristics (object's ID, attributes, instructions, spatiotemporal data, etc.), the smartphone as a mobile device to obtain the object's real-time spatiotemporal data with its system time and GPS module; then the object's spatiotemporal information can be transmitted and stored in a backend server with a database. Meanwhile, the object's spatiotemporal information can also be inquired by smartphone users and other web users. A use case that applied this proposed method to trace object's smartphone information is described later, and the result shows that tracing objects with two-dimensional code has many advantages, such as fast reading and transmitting, low cost, and robust, confidential, and strong readability; furthermore, the proposed modeling method keeps the consistency of object's time and space in CPS. <\/jats:p>","DOI":"10.1155\/2015\/527217","type":"journal-article","created":{"date-parts":[[2015,8,30]],"date-time":"2015-08-30T21:29:46Z","timestamp":1440970186000},"page":"527217","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Two-Dimensional Code Based Spatiotemporal Modeling and Its Application in Object Tracing"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4714-7291","authenticated-orcid":false,"given":"Yanghua","family":"Gao","sequence":"first","affiliation":[{"name":"Information Center, China Tobacco Zhejiang Industrial Co., Ltd., No. 288 Jianguo South Road, Hangzhou 310008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Information Center, China Tobacco Zhejiang Industrial Co., Ltd., No. 288 Jianguo South Road, Hangzhou 310008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanwen","family":"Wang","sequence":"additional","affiliation":[{"name":"Information Center, China Tobacco Zhejiang Industrial Co., Ltd., No. 288 Jianguo South Road, Hangzhou 310008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hailiang","family":"Lu","sequence":"additional","affiliation":[{"name":"Information Center, China Tobacco Zhejiang Industrial Co., Ltd., No. 288 Jianguo South Road, Hangzhou 310008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,8,30]]},"reference":[{"key":"B1-2015-527217","doi-asserted-by":"publisher","DOI":"10.1049\/cce:20050608"},{"key":"B2-2015-527217","doi-asserted-by":"publisher","DOI":"10.1109\/mprv.2007.80"},{"key":"B3-2015-527217","doi-asserted-by":"publisher","DOI":"10.1016\/j.compag.2014.08.015"},{"key":"B4-2015-527217","doi-asserted-by":"publisher","DOI":"10.5860\/crln.71.10.8454"},{"key":"B5-2015-527217","doi-asserted-by":"publisher","DOI":"10.1016\/j.optcom.2014.06.070"},{"key":"B6-2015-527217","doi-asserted-by":"publisher","DOI":"10.1145\/320134.320142"},{"key":"B7-2015-527217","doi-asserted-by":"publisher","DOI":"10.1109\/cit.2012.79"},{"key":"B8-2015-527217","first-page":"59","author":"Soo T.
