- Abstract
With the popularity of the Internet, how to securely transmit and store multimedia data, and effectively access them has become an issue of great concern. High-dynamic-range (HDR) images are predicted to be a future trend and have already received considerable attention. In this study, an object-based method for sharing secret HDR images is proposed. This method comprised three steps. First, HDR images were divided into several objects and the coordinates of the objects and related information were recorded. Second, a method for sharing secret images was used to share the produced objects and recorded information, which were ranked according to importance. Third, a Lagrange interpolation method was used to reconstruct the various objects. The method can be used to maintain high information security and provide a convenient and effective image-restoration method to users. Experimental results confirmed the effectiveness of the method proposed in this study.
