Survey of Secure Multimedia Database Using Public Key Cryptography Method and Optimization Techniques

Abstract – Solving the security issues in multimedia database is important issues in stock market data, consumer behavior data, power consumption data, weather data, and internet based application, content distribution application and medical data emerged as a important solution to provide copyright protection, tamper detection, traitor tracing, maintaining integrity of multimedia data. In earlier existing systems the relational database will be partition, watermarked and directly send to the transmission channel, in these systems while sending relational data from server to client attacker easily copy the data and create same copy of original data. Here there is no security in watermarked relational data. The proposed system before sending the multimedia data it apply the composite partition algorithm, watermark optimization techniques and these data are converting into PDF file format. Encrypt the PDF file using RSA algorithm with Jen’s public key and send it to the client side. In the client side decryption will be done using same algorithm with Jen’s private key to get the original multimedia data and apply the data partition techniques and watermark optimization Techniques. This encryption and decryption technique an attacker copies the data but may not read, insert, delete and update the multimedia data.
