Crypto-secure Data Management with In-Database Blockchain

How do you protect critical data from malicious insiders or compromised admins? See how in-database blockchain makes your data verifiably tamper-proof, using only standard SQL.

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.

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.

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.
