Waveform Audio File Format (WAVE) is an application of RIFF or Resource Interchangeįile Format which stores audio bit streams in “chunks”. Information can be used as a viable method to further secure cloud computing The illustrated method for data encryption of sensitive user Methodology can not only be used as stenographic means but possibly as a techniqueįor data compression. Original wave file to show the variation in encrypted and decrypted data. MATLAB, this matrix defined in the class ‘double’ is put in a graphics file or image file.Īfter encryption the data is retrieved from the image file and compared with the Values corresponding to the sample range is put in a column matrix which is then put inĪ two dimensional matrix having “double” as data-type. This present work puts forth a novel method to encrypt ‘.wav’, which are basically soundįiles in image formats such as PNG, TIF and JPEG. Where the hidden message will not be apparent to an observer. The term applied to any number of processes that will hide a message within an object, Writing) has been used in various forms for 2500 years. Steganography (a rough Greek translation of the term Steganography is secret This method is not only a stenographic means but also a data compression Is used to perform matrix manipulation to encrypt and decrypt sound files into and from JPEG, TIF and PNG along with retrieving them from these image files. We will be elaborating the method of encrypting wave files in popular image formats like Project Title: Encryption and Decryption of Wave File in Image Formats. Whose prayers are a source of determination for us. Truly, sincere and most loving parents, brothers and sisters who mean the most to us, and We would like to admit that we owe all our achievement’s to our At last but not the least we would like to acknowledge the support Wherever we needed, especially our fellow Mr. To our class fellowsĪnd friends, we always remember their cooperation with us. He was available to us whenever and for whatever we consulted him. Instructor Sir Ahsen Malik who kept our morale high by his suggestions and appreciation.
