Crypto-secure Data Management with In-Database Blockchain
#1about 2 minutes
Understanding modern data security threats and vulnerabilities
Traditional security mechanisms focus on access control, but blockchain provides an additional layer to make critical data tamper-proof after a breach.
#2about 1 minute
The implementation challenges of conventional blockchain technology
Traditional blockchain is difficult to adopt because it requires new applications, development methodologies, data management products, and business processes.
#3about 2 minutes
Simplifying blockchain adoption with in-database integration
Integrating blockchain features directly into the Oracle database makes it easy to protect critical assets and documents with minimal application changes.
#4about 3 minutes
Creating and using immutable blockchain tables with SQL
A simple `BLOCKCHAIN` keyword in a `CREATE TABLE` statement creates an immutable table where new rows are cryptographically chained to prevent modification or deletion.
#5about 4 minutes
Verifying data integrity against sophisticated tampering
Built-in procedures can verify the cryptographic chain, and open-source code allows for independent verification even if the database software itself is compromised.
#6about 3 minutes
Detecting a complete data history rewrite attack
To defend against a total system compromise, cryptographic digests can be periodically published to external, public platforms to create an unchangeable verification record.
#7about 2 minutes
Securing mutable data using a blockchain change log
Non-blockchain tables can be protected by using an immutable blockchain table as a cryptographically secure change log, enabling features like Flashback Time Travel.
#8about 5 minutes
Comparing converged vs single-purpose database architectures
Oracle's converged database model integrates multiple data types and workloads into a single system, simplifying development compared to using separate databases for each task.
#9about 2 minutes
Bridging worlds with JSON relational duality views
The JSON Relational Duality feature allows the same underlying data to be viewed and manipulated as either traditional relational tables or as flexible JSON documents.
#10about 3 minutes
Summary and how to get started for free
In-database blockchain makes it easy to add data integrity to applications, and developers can try it now by downloading the free Oracle Database 23c release.
