PROJECTS:

• LSB IMAGE STEGANOGRAPHY

The objective was to send a secret text file encoded inside an image of bmp file format.Encoded the length of the secret text and then encoded the data into the LSB of the image bytes.The decoding process involves decoding the length and then decoding the text bit by bit.The final ouput is the secret text after decoding.

Technologies used: Advanced C File operations,Pointers,Bitwise Operations,Functions,Command Line Arguments.

• INVERTED SEARCH

The purpose of storing an index is to optimize speed and performance in finding relevant documents for a search query.Without an index,the search engine would carry every document in the corpus,which would require considerable time and computing power.

Technologies used: Advanced C File operations,Pointers,Functions,Makefiles,Command Line Arguments.Data Structures - Single Linked Lists and Hashing.

• ADDRESS BOOK

The Address book is a software which keep records of time,phone no,and mail address.User can modify,search,display,modify,save the contact records. Also the record is saved in Human readable format.

Technologies Used: Advanced C File Input Output operations,Bitwise Operations,File Pointers,Functions,Command Line Arguments.

• CAR BLACK BOX

The Car Black box is a project implemented on mircocontroller.This project keeps the record of all the events happening in a car.It also allows user to access the logs by entering a password to get access into the menu to look into the logs.

Technologies Used: Embbeded C,File operations,Structures,Bitwise Operations,Functions.Command line arguments.

• MINISHELL

Minishell is a command processor,typically run in a text window,alllowing the user to type the command which causes actions.Every Operating system provides this Command Line Interface which takes command from the user and provides required output.BASH can also read commands froma file called a script. Like all Unix shells,it supports piping and variables as well.

Technologies Used: Linux Kernel System Calls usage,IPC - Signal handling,String Pointers,Single Linked Lists.

• MP3 TAG READER AND EDITOR

The MP3 Tag reader is a software which will read and display MP3 tag information from MP3 files.The project will be useful to the user who wish to view and collect MP3 tag data.This project can be extended to implement a tag editor,wherein user can modify mp3 tag infomration.

Technologies Used:File operations,bitwise operations,Functions,Command Line Arguments.
