Survey on Multimedia Security and Visual Cryptography
The people using internet has become so extensive across different sectors in day to day life. Security is the important feature different across the platform and mobile applications we use. The important aspect in the sectors is usage of the data having significant role in identifying the user preferences in using the data for video, text and games etc. Due to the large volume of data consumed by the customers is high it‟s difficult for user to identify the identification of the pattern of data that is stored by the remote servers .The advertisements and the thumbnails that come across as your search relates can be seen. This understanding by the service providers or the sites that we visit store our preferences in choosing the content matters .Mostly people chooses the video content for news, entertainment .The people also uses camera for home security and even for live streaming personal mobile cameras used. These all uses huge amount of data. The information loss during the communication between the devices through internet there is a lack of features which even cannot be controlled by the protection software‟s. To avoid all leaky information from the transfer of data technique called visual cryptography is used. In this survey, present an overview of the characteristics, security threats and major security challenges. The contribution of the survey will lead to understand the visual cryptography and security facets of it. The various techniques existing in the visual cryptography will help to figure out the improvement of cryptographic technique in various years. Some identified areas of security which can also affect our day to day life which give motive to find new ways of security mechanism.
