Reversible Data Hiding Method For Improving Security Essay

Information security is a major concept in today’s industrial and computer era, so security must be higher to protect the confidential data. Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken. So I have proposed a new mechanism that will replace the text key with the image pixels and can gain high security which cannot be easy to break without prior knowledge.

Ensuring data security within your organization is crucial if you are to remain compliant against the increasing data security regulations, as well ensuring that you maintain a good relationship with your customers and prospects. Data security concerns the protection of data from accidental or intentional but unauthorized modification, destruction or disclosure through the use of physical security, administrative controls, logical controls, and other safeguards to limit accessibility. Protecting your customer information and ensuring full confidence in your data security measures will put you in good stead for protection against data loss and data security breaches. Data is the raw

Protecting data through cryptography from unauthorized eyes is a high priority for organizations that store personal information. Cryptography is the process of hiding the real meaning of a message through a pre-determined code that is only known to the person encrypting and decrypting a message. Different forms of cryptography can be seen in our everyday life from the word puzzle in daily newspapers to secretaries writing in short hand. Cryptography has been around since the time of the Egyptians and has made many advances through the years.

Data encryption describes the transformation of plain text into a different format that is meaningless read by human eye without being decrypted, so called cipher text, in order to prevent any unauthorized party to obtain information from the document.

Data encryption and decryption have become increasingly important as more people are communicating over the internet. Although cryptology is not new, the demand for this technology has soared as its usefulness for security purposes has become more evident. Cryptology involves converting original messages into non-readable formats and plays an important role in keeping data safe while it is in transit (Agrawal & Mishra, 2012). Two popular forms of cryptology are symmetric and asymmetric.

Due to emerging technologies such as big data, cloud platform and use of internet in day to day activities has led to security concerns for various end users. The transfer and storage of information is a crucial part in many business processes, industrial activities and also in military regime. The information could be in forms such as text data, video, audio, image or e-mail. Cryptography is a method to ensure the security and privacy of data transfer process. Data acquisition is the process of acquiring data accurately with minimum loss of signal being acquired and storing it for further use. Data acquisition and information protection is important in military applications. In the paper, a secure data acquisition system for military application is designed. The FPGA platform is used for implementation of the system design.

With the emergence of rapid growth in technology in our society today, there is an enormous amount of data that is being stored. However, an important question to ask is how is sensitive or important data being protected. One popular method that is currently used for protecting data is through encryption, which is “the process of converting data to an unrecognizable or ‘encrypted’ form.” 1 This process ensures that only authorized individuals have access to the confidential encrypted message. Encryption can be applied to files, folders, storage devices, or entire volumes. Although encryption can be used to protect a variety of data types, there are many different encryption algorithms that can be used. The most common and popular encryption algorithms that are used include hashing, symmetric methods, and asymmetric methods.

Encryption is a method of programming data for security so that it appears to be random data. Only the people sending and receiving the information have the key to decrypt the message, which will put it back into its original form making it readable. The only people with the key are the people who are intended to read the message. Not many people know what encryption is. I took a survey of twenty students and asked two questions. The first question I asked was do you know what encryption means and the second question I asked was have you ever heard of anybody using encryption. This is a chart of the information I received:

Security of information become the fundamental issue nowadays, because of advancement in ICT. So steganography is the best technique to use for security of information

Abstract. This paper is on Cryptography. Cryptography is the art of writing and solving secret messages. People have been using the encoding and decoding of messages with pen and paper since ancient times. Cryptography has played an enormous role in human history as it was used in times of war. With the demand of today’s world of online security, digital Cryptography is in great demand to help people protect valuable information. This paper will focus on the brief history of Cryptography.

Thus, it is essential that computational techniques are performed so that the requirements of information protection are met. In this scenario are presented the two basic types of encryption, symmetric or private key and public key or asymmetric.

Abstract - This paper proposes a data hiding method using adaptive pixel pair matching and data encryption approach for secret data communication. Steganography is the science of hiding secret data in plain sight within cover data so that it can be securely transmitted over a network. The idea of PPM is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighborhood set of this pixel pair according to a given message digit. Before hiding the data within cover image, two encryption schemes chaos encryption for secret messages and selective encryption for cover object are used to increase the data protection. The results will prove that the proposed method not only provides better performance than those of LSB and OPAP, but also is secure under the detection of some well-known steganalysis techniques.

Two set of text images and one true sample image is taken for cryptography. In this proposed work these three images are encrypted into various shares through MATLAB, so that after compiling specific number of share the original image is visible. After encryption the performance analysis is done with the help of PSNR and MSE values.

Mobasseri presented the method of a message either encrypted or unencrypted, can be hidden in a computer video file (containing the picture of, for instance, an innocent 2 year old baby) and transmitted over the Internet, a CD or DVD, or any other medium [5].Shiguo lian provide the main goal of steganography is to communicate securely in a completely undetectable manner and to avoid drawing suspicion to the transmission of a hidden data [4]. III. PROPOSED WORK A. Video Compression Video compression uses modern coding techniques to reduce redundancy in video data. Video compression typically operates on square-shaped groups of neighboring pixels, often called macro blocks. These pixel groups or blocks of pixels are compared from one frame to the next and the video compression code sends only the differences within those blocks.
