Performance over Individual Techniques for Security of Still Image”.

Synopsis Presentation on

Need for Research.Recent advancements in computer technologies offer many facilities:

Duplication. Distribution. Creation. Manipulation of digital contents.

Problem DefinitionRecently Digital Images are utilized in various applications such as: Digital image used as logo on Indian currency note.Digital image of cheques used by CTS of bank.Digital image of patients reports used by doctors. Digital images taken by satellites,etc.

To provide the security & copyright protection for digital images, it is proposed to study of security & copyright protection technique like “Digital Watermarking ”.

Types of Images

Medical Image.

Indoor Image.

Outdoor Image.

Satellite Image.

Types of Watermarks

Contd.Visible Watermark: •Visible watermarks are an extension of the concept of logos. •Such watermarks are applicable to images only. •These logos are inlaid into the image but they are transparent. •Such watermarks cannot be removed by cropping the centre part of the image. •Further, such watermarks are protected against attacks such as statistical analysis

Invisible Watermark :•Invisible watermark is hidden in the content. •It can be detected by an authorized agency only. •Such watermarks are used for content and/or author authentication and for detecting unauthorized copier

Public Watermark :•Such a watermark can be read or retrieved by anyone using the specialized algorithm. •In this sense, public watermarks are not secure. •However, public watermarks are useful for carrying (IPR) information. •They are good alternatives to labels

Contd.Perceptual Watermark :•A perceptual watermark exploits the aspects of human sensory system to provide invisible yet robust watermark

Private Watermark :•Private watermarks are also known as secure watermarks. •To read or retrieve such a watermark, it is necessary to have the secret key.

Fragile Watermark :•Fragile watermarks are also known as tamper-proof watermarks. •Such watermarks are destroyed by data manipulation.
