Improved privacy preserving peer to peer multimedia distribution using recombined fingerprints
- 1. IMPROVED PRIVACY-PRESERVING P2P MULTIMEDIA DISTRIBUTION BASED ON RECOMBINED FINGERPRINTS Domain : Secure computing Guide: Varija Madam Vaishali Misra Laxmi Praythusha Y. Praythusha Sai Chandra
- 2. OBJECTIVE Legal distribution of multimedia contents . Preserve the privacy of both the sender and receiver. Usage of Recombined fingerprints which are more secured. Trace the illegal re-distribution of contents.
- 3. INTRODUCTION Computer security is information security as applied to computers and networks. Anonymous fingerprint has been suggested as a convenient solution for the legal distribution of multimedia contents with copyright protection. Recombined fingerprint approach results in an efficient privacy-preserving and P2P-based fingerprinting system.
- 4. EXISTING SYSTEM Symmetric scheme: Merchant will have fingerprinted copy, the buyer wont be accused of ill- legal distribution. Asymmetric scheme: merchant does not have access to the fingerprinted copy, but he can recover in case of illegal redistribution. Anonymous scheme: The buyer preserves her anonymity and cannot be linked to the purchase of a specific content, except if she participates in an illegal redistribution.
- 5. DISADVANTAGES Developing a practical system using this idea appears difficult. Homo-morphic encryption. Implementation is not simple and requires complex protocol.
- 6. PROPOSED SYSTEM The content is divided into several ordered fragments called segment. The merchant distributes different copies to a reduced set of M seed buyers. The buyers other than the seed ones engage on P2P transfers of the content. The fingerprint of each new buyer is built as a recombination of the segments of its parents.
- 7. A transaction record is created by a transaction monitor to keep track of each transfer between peer buyers. The fingerprint’s hashes are encrypted in such a way that the private key of at least one parent is required for obtaining their clear text. The real identities of buyers are known only by the merchant.
- 8. ADVANTAGES A more efficient and practical system, especially as traitor tracing protocol. Buyers frameproofness is guaranteed. Encryption is only for short bit strings, such as the binary fingerprints and hashes, not to the content.
- 9. SYSTEM DESIGN The system design should focus on the amount of input required, controlling the errors, avoiding delay. A quality output is one, which meets the requirements of the end user and presents the information clearly. SYSTEM CONFIGURATION: Operating system : Windows XP. Coding Language: JAVA Data Base : MYSQL

- 16. MODULES Merchant: He distributes copies of the content legally to the seed buyers. Buyer’s privacy:The identity of a buyer who has purchased a specific content could be revealed by a coalition of two parties. Transaction monitor: It keeps a transaction register for each purchase carried out for each buyer. Database authentication attacks : An attacker may try to obtain the fingerprint of a buyer that is stored in the transaction monitor’s database.

- 22. CONCLUSION Recombined fingerprint strategy provides more security. Buyers need not to compromise their privacy. Recombined fingerprint strategy for data transfer relates with the real time scenarios as the DNA fingerprints.
