摘要：Data Security is one among the foremost necessary challenges being faced by every kind of organizations. Several companies have explored that however vital is that the inform- ation to urge success in their business or operations and extre- mely few have managed to adopt effective measures to create their information secure, avoiding unauthorized access, prev- enting intrusions, stopping secret information revelation, etc . In this proposed technique, the sender is hiding the data which is to sent to the receiver in the form of images. The image is a mixture of the text which is derived from the two techniques of the text steganography which has been derived earlier. The two techniques used are Reflection Symmetry and the Vedic Numeric method. The sender sends the data into partitioned form or we can say the data which is sent by the sender is partitioned into 2 parts and separate-separate part is sent to the two techniques. We are doing this as if the whole text is sent to one technique or vedic technique it will consume more memory. So, the text after being processed by the two techniques is joined to form a whole text and then the text is converted into image by the various methods or algorithms ex.LSB, matrix multiplication. Thus , the text is converted into image that is sent to the receiver. The advantage of the proposed technique is that, since we are hiding the data without changing the structure of the file and by creating the summery of a publicly available text like newspaper article, therefore it will draw less attention to the unintended recipients and hence more security is added to the proposed steganographic system.
