Visual cryptography scheme is a cryptographic technique which allows visual information (e.g. printed text, handwritten notes, and picture) to be encrypted in such a way that the decryption can be performed by the human visual system, without the aid of computers. There are various measures on which performance of visual cryptography scheme depends, such as(More)
Biometrics deal with automated methods of identifying a person or verifying the identity of a person based on physiological or behavioral characteristics. Visual cryptography is a secret sharing scheme where a secret image is encrypted into the shares which independently disclose no information about the original secret image. As biometric template are(More)
To protect the biometric templates and secret key simultaneously fuzzy vault is one of the most popular algorithms. In fuzzy vault generation at first, the preprocessing steps are applied and subsequently, the features are extracted and combined. For recognition, we match the feature vectors of images. The biometric template along with the input key are(More)
This paper introduces recursively hiding patient’s information using XOR based Recursive Visual Cryptography. The XOR based Visual Cryptography Scheme (VCS) encodes a secret image of data into several shares which are not understood by intruders individually. Here (2, 2) VCS is considered for paper. Its pixel expansion has more columns then original and(More)
A tumor is a mass of tissue that's formed by an accumulation of abnormal cells. Normally, the cells in your body age, die, and are replaced by new cells. With cancer and other tumors, something disrupts this cycle. Tumor cells grow, even though the body does not need them, and unlike normal old cells, they don't die. As this process goes on, the tumor(More)
The growth in the usage of internet has increased the demand for fast and accurate user identification and authentication. New threats, risks and vulnerabilities emphasize the need of a strong authentication system. Automated methods based on physiological characteristics of user are widely used to identify and verify the user. Biometric is the technology(More)
In recent years, there has been a rapid growth on information technology for people to communicate on the Internet. Since Internet is public, anyone can easily read the information and perform successful transmissions without protection. In the present era of computers and fast communication, one needs to protect the communicated information from(More)
