Abstract

The present disclosure provides a method and system for creating decentralized repository of fraud IP and publishers using block chain. The block chain network creates a central repository for decentralized shared ledger. The block chain network adds a ledger in decentralized shared ledger for each interaction on an application. In addition, the block chain network authorizes at least one of a plurality of stakeholders to access the decentralized shared ledger after receiving a request from at least one of the plurality of stakeholders. Further, the block chain network analyzes the interaction and past data received from a plurality of stake holders. Furthermore, the block chain network blocks device IPs, device Id'"'"'s, device type and the publishers mentioned in blacklist of the decentralized shared ledger.

5. The computer system as recited in claim 1, wherein the decentralized shared ledger comprises one of private ledger and public ledger.

6. The computer system as recited in claim 1, further, comprising scoring, at the block chain network, the publishers based on the analysis, wherein the scoring is done to specify whether the publishers is using fraud means, wherein the scoring is compared with the pre-defined threshold in order to mark the publishers in the whitelist and the blacklist.

7. The computer system as recited in claim 1, wherein the blacklist and the whitelist comprises device IPs, device Id'"'"'s, device type and the publishers.

8. The computer system as recited in claim 1, further comprising:

verifying, at the block chain network, data received from the plurality of stakeholders with the past data and the interaction, wherein the verification is done after receiving a request from the plurality of stakeholders to add the one or more users associated with the device IPs, the device Id'"'"'s, the device type or the publishers in the blacklist; and

adding, at the block chain network, a ledger in the decentralized shared ledger, wherein addition to the decentralized shared ledger is done based on the smart contracts after verifying that the device IPs, the device Id'"'"'s, the device type or the publishers is fraud, wherein the addition is done in real time.

9. The computer system as recited in claim 1, further comprising:

rewarding, at the block chain network, at least one of the plurality of stakeholders for providing data related to fraud which has been verified and added to the blacklist of the decentralized shared ledger, wherein the reward is updated timely in real time.

10. A computer-implemented method for creating decentralized repository of fraud IP and publishers using block chain, the computer-implemented method comprising:

creating, at a block chain network with a processor, a central repository for decentralized shared ledger, wherein the central repository comprises blacklist and whitelist, wherein the blacklist and the whitelist are created based on the data collected from a plurality of stakeholders related to fraud;

adding, at the block chain network with the processor, a ledger in decentralized shared ledger for each interactions on an application in real time, wherein each of the interactions is associated with one or more advertisements displayed on one or more media devices, wherein the addition is done based on a smart contract;
