Abstract

Now-a-days the usage of internet increases tremendously so, there is a need of security for the data. Cryptography is a process of scrambling the data into unknown format which provides security to the data. Modern cryptography is mainly based on mathematical theory and computer science practice. Cryptography process is done with the help of encryption and decryption. The basic two ideas behind the cryptography technique are substitution and transposition. This paper presents a multistage encryption algorithm. At the end of each stage an intermediate cipher is produced. The key is generated by using SEEDED SDES algorithm. Final cipher text is derived from the local binary pattern (LBP).

Keywords

Decryption, Encryption, Railference, SEEDED SDES Key Generation, Substitution, Transposition.

Abstract

The most precious field in digital image processing is diagnosing the internal activities of human body. Brain is one of the critical part in human body. In the current era cancer is a challenging in medical field. Identification of tumor in brain is very difficult. Segmentation is a kind of method in digital image processing used to divide the image into number of parts with specific regions. It is important to notice that resolution is the key factor in identification of tumors. In this paper we proposed efficient modified K-mean clustering along with triangular model for detection of brain tumor. Modified K-mean clustering includes image enhancement for clear detection of tumor using gradient profile sharpness. Further tumor is detected using triangular model.

Keywords

Image Segmentation, K-Means Clustering, Mri Images, Triangle Model, Tumor Detection.

Abstract

Steganography is the principles and techniques of embedding data within other data. Cryptography is the principles and techniques of changing the data one form to another form. Image Steganography is the process of hiding data within an image. Steganography along with encryption techniques provides an additional security to the data. Several techniques exist for image steganography, in this work, a new lossless image steganography technique along with cryptographic method is presented. Lossless compression is a class of algorithms that allows the original data to be perfectly reconstructed from the compressed data. Present work concentrates the lower nibble of pixels in the cover image for embedding the information; further encryption techniques will be applied. It is not possible for the hacker to retrieve the secured data from the cover image.

Keywords

Compression, Cover Image, Cryptography, Lossless, Nibble, Steganograpy.

Abstract

During the day; Technology is Cloud, where people can share resources, services and information across the Internet. Due to information on the Internet, security is considered a major problem. The information should be protected by an unauthorized user and should be sent to a person with a private and confidential intent. On this proposed work, to provide a secure method, secure connection, authentication, confidentiality and third-party data protection in cloud computing. In the combination of the Advanced Encryption Standard (AES) and Cryptographic Curve Cryptography (ECC) analyzing of different parameters like storage, encryption time, decryption time and correlation. The results show that the impact of this integrated approach is more important than the other secure algorithms.
