The major concern to authenticate an audio signal is restoring its basic audible properties and providing such a way that may not produce any unusual perception to listeners. Therefore, authenticating an audio signal needs to embed as less as minimum security code within tolerable range of perception. In this paper, perceptual encoding has been applied for structuring song signal in a specified manner with less modification of its amplitude values and followed by embedding formatted data in skewed pattern that will use for verifying any type of alternation by comparing its own structural format and systematic structure of song signal with neighbouring sampled values. A comparative study has been made with similar existing techniques and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav") stereo sound file.

This paper presented a technique to organize the digitized map of a very large area, using a flat-file system (without using databases); depicting necessary and useful information regarding land usage of the area, which can also be viewed as a land-type-data bank, where all the necessary information regarding the type of the land, owner etc. are kept. While associating data with each individual region, a priority value is also incorporated, where a lower value of priority signifies, higher possibility of the land to be selected for acquisition. As per needs to acquire lands for the construction of new utility services such as railway tracks, roads etc., the technique, upon input the source and the destination location, suggests the most suitable path, in terms of optimal costs, which is dependent on the parameters like compensation needed to pay during land acquisition (compensation amount increases, for acquiring more fertile lands), the length of the path etc. The suggested optimal path is presented onto the map graphically assisting the engineers involved in the work for proper implementation and utilisation of the land.

Embedding uniqueness in characteristics of song signal and accustoming changes of environment is one of the challenging issues for researchers with maintaining its audible quality. Researchers are modifying or manipulating audio signal properties for generating uniqueness in content such a manner that will not vary so much in changed environment or changes can be easily defined due to unique structure of song signal. In this paper, an approach has been made based on defining a symmetric structure of song signal, followed by some secret code embedding in a specified manner will not alter the trade off ratio of embedding/modifying data but provide uniqueness in properties, even retain the properties in changing environment/ format. Therefore, authentication of song signal is easily achieved with these self manipulated properties. A comparative study has been made with similar existing techniques and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav") stereo sound file.
