However, most of the existing multilevel secret sharing (MLSS) and multigroup secret sharing (MGSS) schemes mainly focus on how to protect a secret between one or more groups. In this paper, we propose a polynomial-based scheme to share multiple secret images both within a group and between groups. The random elements\u2019 utilization model of integer linear programming is used to find polynomial coefficients that meet certain conditions so that each participant holds only one shadow image and some of them can recover secrets of both intergroup and intragroup. In addition, our scheme based on polynomials has the advantage of low computational complexity. Theoretical analysis and experiments show that the proposed scheme is feasible and effective.<\/jats:p>","DOI":"10.1155\/2021\/9960998","type":"journal-article","created":{"date-parts":[[2021,7,2]],"date-time":"2021-07-02T21:20:14Z","timestamp":1625260814000},"page":"1-14","source":"Crossref","is-referenced-by-count":2,"title":["An Intragroup and Intergroup Multiple Secret Images\u2019 Sharing Scheme with Each Participant Holding One Shadow Image"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1170-7127","authenticated-orcid":true,"given":"Jiayu","family":"Wang","sequence":"first","affiliation":[{"name":"National University of Defense Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6388-1720","authenticated-orcid":true,"given":"Xuehu","family":"Yan","sequence":"additional","affiliation":[{"name":"National University of Defense Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8049-4893","authenticated-orcid":true,"given":"Jia","family":"Chen","sequence":"additional","affiliation":[{"name":"National University of Defense Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9778-7783","authenticated-orcid":true,"given":"Yongqiang","family":"Yu","sequence":"additional","affiliation":[{"name":"National University of Defense Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1145\/359168.359176"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/mark.1979.8817296"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1007\/BFb0053419"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1007\/s11042-013-1784-2"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.optlastec.2013.04.018"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1520-6440(199807)"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/tip.2006.875249"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s11554-015-0540-4"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/s11042-014-2438-8"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/tcsvt.2020.3025527"},{"issue":"2","key":"11","first-page":"118","article-title":"A new assessment measure of shadow image quality based on error diffusion techniques","volume":"4","author":"X.
