4. Problem Statement
The information security is becoming a big challenge in the current digital
age. For surveillance and timely alert generation of threat, A hidden Army of
Bots is required to protect data, assets and defense installation.
 Organizational Security.
 Centralised Database.
 Increase in piracy threats and illegal use of
confidential data.

5. Existing System
Systems like Kaspersky ant-viruses, Engine Firewall, McAfee Total
Protection, centralized servers etc. In these we can find many system handling
many security and external threads by following various techniques. They all
provide security up to some extent yet unfortunately even in presence of these
system we get hacked up and loss our confidential information.
Drawbacks:
 Centralized network of simple server client communication.
 All Data residing on single place.
 Simple firewall protection services.
Too expensive for more reliable services.

6. Army Of Hidden Bots
Army of Hidden Bots Act as a reliable solution of any organizational
threats. Because they act as a distributed network of different blocks connected
together in the manner of Block chain. We find this solution promising our need
because.
 Give rise of Block chain as distributed network.
 Meeting the new standards of protection.
 More than simple firewall protection services.
 Cheap and more reliable services.

7. Proof Of Concept
Implementation of blockchain on multiple computers.
Communication between python and node.js
Face recognition on each system.
Communication between node.js and python.
Transfer of image from one system to another system.

8. Working Methodology
Access
Request
Communicate with Network
For Authorization
Peer - 1
If Recognized then Access Granted

Block Chain Network

9. Facial Recognition
Facial Recognition works in 3 phases as :
 Data Gathering
 Training of the Recognizer.
 Facial recognition using recognizer.

10. Recognition Technique(LBPH):
LBPH(LBPH (LOCAL BINARY PATTERNS HISTOGRAMS) is the most fast and yet efficient
technique for facial recognition by converting each image into a binary pattern. This technique
analyzed each dataset image independently and develop its trainer and characterize each
image in the dataset locally using the Open recognizer. We use it because of.
 Simpler and fast working.
 Evaluate the result to each of the images in the dataset.
 Utilize less processing power.

11.  Open source collaborative effort to advance cross-industry blockchain technologies
 Hosted by Linux Foundation
 Has a global collaboration with finance, banking, supply chain, manufacturing and te
chnology companies
 Works to standardize the protocols
 Launched in 2015
 Goal is to “Create an enterprise grade, open source distributed ledger framework a
nd code base"
Hyperledger:

13. • Private and Permissioned Blockchain
• Nodes are run by known whitelisted organizations
• High transaction throughput performance
• Privacy and confidentiality of transactions and data pertaining to business
transactions
• No 51% attack
• PBFT consensus mechanism used
• No mining is involved - but basics of blockchain is followed
○ It has block immutability
○ Eliminating double spending
Hyperledger Fabric :

14. • Based on docker architecture
• Docker is sort of like VM
• Docker container , Docker images and Docker hub
Architecture

15. • Fabric-CA (Certificate Authority)
• Fabric Peers
• Fabric Orderers
Fabric components:

16. • Peer is where the Ledger is present
• It also maintains the world state
• Peer can add or query the data from the ledger
• We can have more than one peer - On production we need more than one
• All peers synchronize - Once connected to the network
• Couchdb is used as database
Fabric Peers:

17. • Ordering service is the heart of the consensus process
• Anything that has to be committed needs to be processed through the ordering servi
ce
• Ordering service creates the Blocks
• This sends the block to the peer to update
Fabric Orderers:

18. • Define policies around the execution of transactions
• Define which peers need to agree on the results of a transaction before it can be
added to the ledger (endorsing peers)
• Peers A, B, C, and F must all endorse transactions of type T
• A majority of peers in the channel must endorse transactions of type U
• At least 3 peers of A, B, C, D, E, F, G must endorse transactions of type V
Endorsement Policy:

26. • Built in Javascript
• Works on top of fabric
• Model your business blockchain network
• Deploy Smart contracts / chaincode on fabric network
• Generate REST APIs for interacting with your blockchain network
• Generate a skeleton Angular application.
• Generates playground to test business logic
Hyperledger Composer:

27. Smart contract / chaincode

32. • Docker swarm mode
• Direct communication
