Blockchain for Data Security

Blockchain for Data Security

1. Concepts and Definitions

   • Bitcoin is not blockchain
   • Underline technology that enables bitcoin
   • Built to run across multiple computers and location
   • Tamper resistant
   • Most important function: Trust in the data
   • Ensures your data is encrypted
   • Each block contains information
     • When new information is added, a new block is added

2. Potential Problems that Solves

   • Cloud Storage
     • Storj
       • Uses decentralization
         • Improve the cloud storage security
           • Encrypt personal files
             • Using cryptography
   • Voting
     • No doubt about the authenticity of the result
       • Immutable
       • Irreversible
   • Traceable secure transactions
     • Each piece of information
       • Recorded and confirmed for all parties involved
   • Minimization of human errors
     • Possible to eliminate the need for login and passwords
   • Securing the Internet of Things
     • Monitoring and record communications
       • Between multiple connected devices
   • Transparent supply chains
     • Ensure complete visibility
       • Into the supply chains of all products
         • With unique digital identification

3. Uses

   • Verifying the Validity of Software Downloads / Updates
     • In 2016
       • 127 million malware was mostly created by a software virus
         • Designed to infect computers
           • Can often easily pass through the inexperienced eye
     • Blockchain allows you to assign unique identification hashes
       • Both to downloads and updates
         • To reduce the chances of infecting their systems
   • Biometric Private Keys / Digital Identities to Replace Passwords
     • Blockchain doesn't need to use passwords
       • It's based on private multi-step authentication keys
         • Collected from biometric data
           • To ensure the security of user information
   • Preventing Hacks on Automated Systems
     • Algorithms that recognize invalid commands
       • No risks
   • Distributing Public Key Infrastructure and Multi-Signature Logins
     • Multi-device authentication system
       • Authorizes a user when he has access to multiple devices
   • Provenance for Computer Hardware to Prevent Foreign Intrusion
     • Help in investigations in the event of an attack
     • Blockchain accounting books
       • Providing immutable records
         • Computer's manufacturing
         • Transportation history
   • Preventing False Data From Entering a System/Ledger
     • Data filtered by this network tend to be more reliable
       • Since the security of multiple nodes lends itself
         • To greater verification and prevention of manipulations
           • Generating greater precision when detecting false information

4. Benefits

   • Resiliency
     • Disponibility of data
       • Needed in a production environment
     • Decentralization
       • Same data will be saved on each node on a blockchain
     • Very low or zero percentage of data loss
   • Integrity
     • Data remains intact and complete
       • Keeping its veracity
     • Data within the blockchain can't be updated
       • Without first reaching an agreement
         • Between all the members of the chain
   • Privacy
     • GDPR is incompatible with the Blockchain system
       • Due to its immutable feature
         • Methods to improve the compatibility of these
           • Are being worked
     • Each user can have access to the entire blockchain
     • Blockchain seeks to empower people of their data
   • Trust
     • Network members can be partners in a supply chain or other businesses
     • All partners have the same privileges
