In ICN the content/information segment is termed as Named Data Object (NDO). It can be any digital content such as an image, a video, a webpage, a document, etc. And it possesses a name that is location independent. Moreover, data and probably metadata are used for the description of the NDO. The design of NDO varies based on the various approaches used for implementing ICN. Furthermore, Flat and hierarchical naming schemes are used in ICN. However, most recent ICN approaches allow hybrid naming which is a combination of both flat naming and hierarchical naming scheme. And most importantly any of these naming schemes should have the following features: Uniqueness: It should be assured that content identification is unique.Persistence: To assure that the content name is unique and valid during the lifetime of the associated content.Scalability: It should be able to support different namespace scales. Thus, tiny and big namespaces should be served in the same way with no limitation regarding storage location, nature of content or any other characteristics.

A variety of digital information, for example, pictures, recordings, melodies, and essential archives, is being published or exchanged between people, organizations, and associations every second. The digital content and online transmission of data are fast, less expensive, and easy to store and process, and result in high-quality transmission and distribution. On the flip side, new security-related problems have arisen, such as to how to trust, identify, or authenticate the right owner/creator/correspondent, and how to confidentially and reliably protect the multimedia information/intellectual property (IP). With the illegal downloads, distributions, copying, and use of a variety of data, such as multimedia, web-published data, broadcast information, IP, and commercial designs, the creators/producers/authors/editors/distributors are experiencing great losses, and hence digital rights has become the need of the hour.
Basic Fundamentals, Definitions, and Key Terms

Analog audio and video signals are usually converted into digital form within physical proximity to the source, ranging from a few inches to tens of feet, perhaps a hundred feet at most. Once in digital form, many things can be done with it, including messing it up unless it’s handled with care. Analog content, or content in analog form, requires an analog transmission channel, or it must be converted to digital form for transmission on a digital transmission channel. Digital content requires a digital transmission channel. Analog content by nature must run in real time. Even variable motion recording and playback equipment records the material at normal speed and simply repeats the same frame over several repetitions of vertical synchronizing time base to get the appearance of slower motion, or speeds up several frames over a period of time, giving the viewer the same information faster so it appears in fast motion.

Steganography is useful for those who share their own digital work over the Internet to allow complete local access control to their works [21, 22]. In access control systems for digital content distributors, the data or information is hidden but the content of the page is not hidden. The owner receives an access request from anyone visiting the page. Then the owner may create an access key for the customers who wanted to read the information contained in the page.
