Digital data security and hiding on virtual reality VDO 3DGIS-Map

Todaypsilas Information Technology supports varieties of e-commerce, in particular on-demand services such as news, message, seminar and presentation speech to message, and 3D Video GIS. Each service can have value-added by embedding other hidden-service within the main service, hence promoting value-added to the service. The value-added services are accomplished by using the technique of Multiple Keys and Messages Embedding (MKME), which hidden-contents can be retrieved only by applying the correct corresponding decryption keys This paper presents the design and algorithm for multiple keys and messages embedding on 3D Video GIS, based on Steganography concept. The quality of the resulting product was also investigated. The main data used is geospatial video, which is primarily used by the elderly and disables people so that they can feel the surroundings on their desktop while sitting at home.
