Protection of 3D models using cross recovery

Format-Compliant Selective Secret 3-D Object Sharing Scheme

“…In this section, we compare our proposed method with recent state-of-the-art S3DOS schemes: methods by Elsheh and Hamza [10], Anbarasi and Mala [11], Tsai [13] and Lee et al [14]. Table V presents several properties we want to [10], [11], [13], [14].…”

“…Through their application, Lee et al presented an efficient method to obtain a group of n 3D objects when at least k of them have been downloaded in high quality [14]. This method's objective is to ease 3D object visualization by letting at the users a render of a simplified version when the original object is downloaded.…”

“…Elsheh and Hamza [10] Anbarasi and Mala [11] Tsai [13] Lee et al [14] Our scheme compare. Concerning shared data, our proposed scheme, like the method of [13], shares geometry by protecting all vertices since we want to protect relevant geometrical information of the secret 3D object.…”

“…In the last few decades, many methods of SS have been applied to the field of image processing as Secret Image Sharing (SIS) [6]- [9]. Using this same direction, several papers have been published on Secret 3D Object Sharing (S3DOS) [10]- [14]. Elsheh and Hamza proposed to directly apply SS schemes on 3D objects to protect them using Blakley's SS scheme [5] or Thien and Lin's SIS approach [7].…”

“…In 2016, Tsai proposed a S3DOS scheme based on reversible 3D data hiding which shares only an approximated geometry of the secret 3D object in cover 3D objects [13]. Recently, Lee et al presented an application case of SS for streaming purposes in order to obtain a group of n 3D objects when at least k of them have been downloaded in high quality [14].…”
