The design objective for this macro processor is to be as powerful as possible and yet remain simple to use and implement. It was developed primarily to manipulate computer programs where the processor takes a symbol table plus a program template containing macros and produces a specific program. This approach is applied to the macro processor itself. The macro processor template may be run through the portable macro processor to produce a version tailored to the local computing environment. Example: In particular, it is easy to produce a IBM 360 version of the macro processor. We consider macro processors to be a particular kind of translator writing system rather than simply a mechanism for performing textual replacement.

The performance of common speaker verification (SV) system vastly affected when speaker model training is done in the speech sample that recorded done by one device and the testing is done in another device. It is a major problem of speaker verification system in multi-device environment. In this paper we report the experiment carried out on the recently collected speaker recognition database Arunachali Language Speech Database (ALS-DB) a multilingual and multichannel database to study the impact of device variability on speaker verification system. The collected database is evaluated with Gaussian mixture model and Universal Background Model (GMM-UBM) and Mel - Frequency Cepstral Coefficients (MFCC) combined with prosodic features as a front end feature vectors based speaker verification system. The impact of the device both matching and mismatch in training and testing has been evaluated in text independent manner. For matching condition of device we have found Equal Error Rate (EER) 7.50% with minimum Detection Cost Function (MinDCF) value 0.1062 and for mismatching condition of devices that of 18.70% with MinDCF value 0.3425. The performance of the SV system has degraded approximately 11.00% due to mismatching condition of devices in text independent speaker verification system.

A biometric is defined as a unique, measurable, biological characteristic or trait for automatically recognizing or verifying the identity of a human being. Statistically analyzing these biological characteristics has become known as the science of biometrics. The very basis of this Biometric Cryptosystem lies on the very fact that some features of human body are significantly unique to each and every human in the world, such as fingerprint, DNA sequence, Iris, etc. Using those biometric we can generate an exclusive key that will be unique for each and every individual. Now having generated these keys we can use them for encrypting our message. And as because these keys are uniquely generated for individual persons there’s no chance of there will be a matching keys. Moreover as I use RSA algorithm based encryption technique so the encryption lies on two basic sets of keys to decrypt the message. Hand geometry is a kind of biometric measure where Data is read and processed independently of the position of the user hand. This is done by analyzing the curvature profile of the hand contour, making the feature extraction process rotation and translation invariant. In my proposed work first I identify keys from hand geometry and after that by using those keys I can encrypt an SMS in mobile android by using RSA algorithm.

We all know how the homosapiens according to Darwin (scientist), how our ancestors cultivated the communications through writings & painting’s about their historical times and how our great Indus civilisation, other civilisation’s progressed. As we entered in to so called millennium we progress with giant feet’s but how do we need to know what and where but Who performed and Why? Absolute answer would be a very rare but the existing monuments had given many answers about history. For example, Shah Jahan the great Mugal ruler was good engineer by his works of monuments. Basically we know everything about our past by inscriptions, scriptures, books and past monumental work. We know that population of India is increasing day by day and at the same time we have to protect our Indian monuments for the future generation population and also for other people who wanted to visit India but cannot afford to come to India and appreciate the Indian culture as well as Indian heritage. Sometimes it is difficult to allow to show these monuments because of their geographical presence and also sometimes because of security problems. This may be possible through 3D augmentation. This paper is an initiation to introduce a technical aspect of heritage sites augmentation.
