A Secure Image Steganography Using Improved Lsb Technique And Vigenere Cipher Algorithm

Steganography is the practise of concealing information in another type. Many different carrier file formats may be used, but digital images are most popular. This involved with the stronger and weaker image hiding, file compression, file locking, file encryption and file decryption. The applications are having the capability for establishing the characteristics like absolute confidentiality, whereas other applications are in requirement of secrecy on a large message. The aim of this analysis is to include a description which outlines the criteria of a good steganographic algorithm and briefly discusses best techniques which are in use. The knowledge is processed electronically because of development in the area of ICT. Therefore, privacy and security has been a big concern. It may also be used to encrypt messages which are embedded in a digital host before being sent to the network, thus their existence is uncertain in nature. The mechanism of hiding and encrypting sensitive data may be extended to the copyright protection of interactive media, audio, video and images. It can also be utilized to further protect the integrity of digital records. This is the practise of concealed touch. The objective towards aim is to submit the documents and to create numerous uses, then the message to be hidden is encoded with a vegenerous chip algorithm and saved in an image with the LSB steganography and finally, the virgin chip decryption algorithm can be used to obtain a real code.
