  US 20100027791 A1Abstract
  A method and system for encoding visual information are described. An image is divided in to n number of patterns. Each pattern is mapped on a matrix i.e positioned on X and Y-axis. The patterns are then arranged in a different and new shape for e.g. a rectangle, to that of the original shape of the image but having the same number of patterns or same area. The patterns of pixels are then relocated in the new shape and a matrix is again mapped for the new arrangement of patterns. A key is then generated comprising the information of the encrypted and earlier image. In order to decrypt the encrypted visual content or the encrypted image, the player reads the key or encrypted visual content and decrypts the encrypted visual content or image by means of the information provided by the key.
  The instant invention relates to the field of image processing, encryption and decryption of digital visual content and in particular to fuzzy protection of visual content by disallowing unauthorized access of visual content. The present invention is also related to Coder/Decoder application in the field of image processing.
  Entertainment industry includes movie, cable TV, screenplays etc. Movie has been a major industry in the world of entertainment. The production of a movie requires a huge sum of money, talent of people and a great amount of effort. These efforts, money and talent of too many people involved in the formation of a movie or a screenplay bear no fruits at the end if copied or accessed by unauthorized people. Also, there are confidential images or moving pictures, which might be of ultimate secrecy to the welfare of the nation and requires strong security. Thus, in order to protect such crucial visual information from unauthorized accesses, a method and a system for securing digital visual content are in core need.
  Television encryption, often referred to as "scrambling", is used to control access to pay television services, usually cable or satellite television services. Pay television exists to make revenue from subscribers and sometimes those subscribers don't pay. The prevention of piracy on cable and satellite networks has been one of the main factors in the development of Pay TV encryption systems.
  In order to achieve the above objectives and advantages, the instant invention encrypts visual content i.e. still or moving image so as to disallow any unauthorized person to access the visual content.
  The system CODEC (Coder Decoder) is then combining two separated parts:
  The aspect ratio of a two-dimensional shape is the ratio of its longer dimension to its shorter dimension. It is also applied to two characteristic dimensions of a three-dimensional shape, especially for the longest and shortest 'axes' or for symmetrical objects (e.g. rods) that are described by just two measures (e.g. length and diameter). In such cases, the aspect ratio may evaluate to a value less than one (e.g. consider very short and very long rods).
