Improvement in imaging technology and the ease with which digital content can be reproduced and manipulated, there is a strong need for a digital copyright mechanism to be put in place. There is a need for authentication of the content as well as the owner. It has become easier for malicious parties to make scalable copies of copyrighted content with any compensation to the content owner. Digital Watermarking is being seen as a potential solution to this problem. Different watermarking schemes have been proposed, but attacks on a watermarked image are distortions in the watermarked image. These attacks may be intentional or unintentional; the attacks are classified as geometric attacks. This paper presents a comprehensive survey of the current techniques that have been developed and their effectiveness. Digital watermarking was developed to provide the copyright protection and owners' authentication. Digital image watermarking is a method for embedding some data into digital image sequences. E.g. Text image, image data, in this paper, the survey on image watermarking and its methods, Attacks on watermarking, classification of watermarking, and applications. We aim to produce a comprehensive review of the existing literature available on DCT and DWT based mostly on digital image watermarking, to develop a useful digital image watermarking methodology.

The Travelling Salesman Problem is very suitable obstacle from NP set. It is still one from NP-hard. The result of TSP has wide range of practical application so; it is required to have one dynamic result for TSP NP-hard problem. A lot of efforts were provided in the prehistory to give time efficient solutions for TSP. Solution should be correct and close. This paper analysis on going the dynamic result to the obstacle. It uses the Genetic Algorithm to optimize TSP. It is also used for the reducibility of time complexity of TSP.

In the present day scenario, many times we see that the garbage bins or Dust bin are placed at public places in the cities that are overflowing due to an increase in the waste every day. It creates the unhygienic condition for the people and creates bad smell around the surroundings this leads in spreading some deadly diseases & human illness, to avoid such a situation we are planning unique ID will be provided for every dustbin in the city so that it is easy to identify which garbage bin is full. When the level reaches the threshold limit, the device will transmit the level along with the unique ID provided. These details can be accessed by the concerned authorities from their place with the help of the Internet and immediate action can be made to clean the dustbins. This paper is a proposed IOT based smart waste clean management system that checks the waste level over the dustbins by using Sensor systems. Once it detected immediately this system altered to concern authorized through GSM/GPRS For this system used Microcontroller as an interface between the sensor system and GSM/GPRS system.
