V. Issues regarding the Public Key Cryptosystem With public keys being unique and the algorithms creating extremely hard to crack encryption. Although with this method, it also is extremely taxing on the computer system to encrypt and decrypt the message. Which is one of the main reasons that private key encryption is still a thing to this day. The reason for this is the whole idea behind a public key cryptosystem. To be able to release the encryption key without revealing the private decryption

The most important and significant challenge in the big data is to preserve privacy information of the customers, employees, and the organizations. It is very sensitive and includes conceptual, technical as well as legal significance. Any collected information about a person, when combined with other sets of data, can lead to the finding of persons secret and private information. “ As big data expands the sources of data it can use, the trustworthiness of each data source needs to be verified, and

1.1Overview VISUAL cryptography (VC) is a branch of secret sharing data. In the VC scheme, a secret image is encoded into transparencies, and the content of each transparency is noise-like so that the secret information cannot be retrieved from any one transparency via human visual observation or signal analysis techniques. In general, a -threshold VC scheme has the following properties: The stacking of any out of those VC generated transparencies can reveal the secret by visual perception, but the

2. System Analysis 2.1 Existing System kallahalla et al has been proposed cryptographic storage system that helps user for securing his data by sharing data for the un trusted worthy servers based on the techniques that divides files into file groups and encrypting each file group with a file block key. In some times file block key also need to be changed and distributed for a user revocation, so the system should have heavy key distribution overhead. in other schemes have a data sharing on un

Secure Socket Layer:- Secure socket layer is a combination of public key and symmetric key encryption to secure a connection between two systems. Secure socket layer is runs above the TCP/IP protocol which is responsible for the transport and routing of data over network. The transport layer security protocol evolved from SSL and has largely superseded it. The term Secure Socket Layer and SSL/TLS are still commonly used.

1. Type of operations used for transforming plaintext to cipher text. All encryption algorithms are based on two general principles. Those are substitution, in which each element in the plain text is mapped into another element and transposition in which elements in the plaintext are rearranged. The fundamental requirement is that no information be lost. Most systems referred to as product systems, involved multiple stages of substitution and transposition [2]. 2. The number of keys used: If sender

3.3.7 Decryption When a live finger is placed on the scanner at the time of authentication, the decryption process needs to be initialized. With a slit of micorseconds the fingerprint image is analyzed . The RSA key generation algorithm is performed on the fingerprint image captured and the current private key generated is crossed checked with the encrypted fingerprint images existing(Fingerprint template) if their private key matches. If the current private key generate matches witht the private

Amanda V. Jennings Professor Tres Brooks CCT 110 November 24, 2014 Encryption “Encryption is a way to enhance the security of a message or file by scrambling the contents so that it can be read only by someone who has the right encryption key to unscramble it” (Microsoft). Encryption uses an algorithm to change plain text data to cipher text. It played a very important role in wars and in military circles to protect top secret information from foreign countries. There are two types of encryption
