Abstract: 

Generally, we send many pictures to our friend’s relatives and others. The photos that may contain personal information so keeping them to at most secure is the important thing. So in this project, we implement the idea of encrypting and decrypting the image using BLOWFISH algorithm.

Encryption Process:

Data image as a plaintext and the encryption key are two inputs of the encryption process. In this case, original image data bit stream is divided into the length of the block of Blowfish algorithm.

Decryption Process:

The encrypted image is divided into the same block length of Blowfish algorithm from top to bottom. The first block is entered to the decryption function and the same encryption key is used to decrypt the image but the application of subkeys is reversed. The process of decryption is continued with other blocks of the image from top to bottom

The Single Module Present in the application is

User:

In this application user will register and log in with the username and password, after logging in the user will upload the image which is to be encrypted and then after encrypting the user will get a secret key to the user registered email id using the key and encrypted image

Existing System:

The existing system for this project the text information is encrypted by ASCII values or any special characters. In the existing system, didn’t use the safely sent the encrypted information into the mail. The hackers easily access that information. The encrypted text is didn’t restrict any secret key. So that information easily decrypted. Two common drawbacks of the visual cryptography scheme (VCS) are the large pixel expansion of each shared image and the small contrast of the recovered secret image

Proposed System:

Blowfish to be a publicly available cryptographic algorithm with the potential to replace DES. Blowfish is a 64-bit symmetric block cipher that uses a variable-length key from 32 to 448-bits (14 bytes). The algorithm was developed to encrypt 64-bits of plaintext into 64-bits of ciphertext efficiently and securely. The operations selected for the algorithm were table lookup, modulus, addition and bitwise exclusive-or to minimize the time required to encrypt and decrypt data on 32-bit processors

Abstract:

“Review Based Rating Prediction” is a web application developed in java. This application relates to the features obtained by analyzing textual reviews. In this application the information retrieval retribution to analyze a utility function over a product. A product utility is a measure that shows how much it is preferred according to user’s current context. This context inference is distinguished from the user’s review history and the item review history. Based on the users purchased history and the rating history the present product rating will be automatically predicted. The predicted ratings can generate recommendations that are product-based and will appear at the recommended items list in the product page. This project predicts the rating score that a user will rate an item.
