Blockchain Emerges as a Potential Safeguard for Government Data Management Amid Cybersecurity Vulnerabilities
Oct 10, 2024 at 03:00 pm
As data breaches become more prevalent, blockchain is gaining attention for its ability to protect sensitive information. Both Navalan and Daugherty believe that blockchain can be leveraged in this kind of situation due to its decentralized, traceable, and tamper-resistant nature.
The Philippines’ Department of Foreign Affairs (DFA) recently disclosed that the personal data of around 28 million passport holders might be vulnerable due to the absence of a robust cybersecurity system. This revelation emerged during a Senate finance subcommittee hearing on the DFA's proposed PHP27.4 billion ($481 million) budget for 2025.
Assistant Secretary Adelio Cruz of the DFA's Office of Consular Affairs expressed concern over the lack of adequate cybersecurity measures to protect the vast amount of sensitive data handled by the department. This vulnerability could lead to potential data breaches or unauthorized access, putting the personal information of millions of Filipinos at risk.
To address this pressing issue and enhance the security of government data, blockchain technology is presenting itself as a promising solution. In an interview with CoinGeek, Emman Navalan, CEO and Founder of Viridian Technologies, shared his insights on how blockchain can improve security and transparency in data management, highlighting its potential for adoption by the Philippine government. At the same time, SmartLedger Chairman Byran Daugherty explored how blockchain solutions like Certihash can be utilized as an alternative cybersecurity measure.
Enhancing data security with blockchain
With the increasing prevalence of data breaches, blockchain is gaining attention for its capability to safeguard sensitive information. Both Navalan and Daugherty expressed their belief that blockchain can be effectively leveraged in this scenario due to its decentralized, traceable, and tamper-resistant nature.
“The recent breach involving the personal data of 28 million passport holders in the Philippines underscores the urgent need to rethink traditional government cybersecurity infrastructures,” Daugherty told CoinGeek. “This situation demonstrates how centralized systems remain vulnerable to mass data leaks, making blockchain an appealing alternative. By utilizing decentralized, immutable architecture, blockchain ensures data integrity, traceability, and tamper resistance, providing robust defenses against both external and internal threats.”
“Moreover, blockchain offers the transparency needed to rebuild trust in data management. Decentralized IDs can give individuals control over their data, allowing them to track when and by whom it is accessed—critical in places where public trust is fragile. For governments, this enables accountability and transparency in data handling, helping to mitigate insider threats and unauthorized access,” the SmartLedger chairman added.
For his part, Navalan stated, “Blockchain has the capability to monitor transactions on-chain.” This entails that each transfer of information is recorded and can be traced back, minimizing the risk of unauthorized access. Blockchain's decentralized architecture employs public and private keys, ensuring that only the intended recipient can access specific data. “This helps make sure no middleman can access information,” Navalan explained.
The technology's tamper-resistant nature is another significant advantage. Data stored on the blockchain can be encrypted, and any unauthorized changes are immediately detected. “You have higher security in terms of tampering or altering specific information,” Navalan added, highlighting blockchain's potential to improve security in government-held records.
Transparency and accountability in blockchain
Beyond security, blockchain offers unmatched transparency. Every transaction is recorded on a public ledger that can be audited, ensuring that data access is always traceable.
“Blockchain allows you to set individuals who would receive this information for verification,” Navalan highlighted. This transparency minimizes the risk of unauthorized access, though Navalan cautions that blockchain alone isn’t enough—it still requires additional security layers, such as Web2 technology.
Emerging technologies like zero-knowledge proofs and multi-party computation further enhance blockchain's security, providing additional layers of protection for data. “These technologies work in parallel with blockchain to prevent unauthorized access,” he said.
At Certihash, Daugherty and his team focus on real-time detection and response to breaches using blockchain-based systems like Sentinel Node. This solution offers near-instantaneous flagging of unauthorized changes and attacks. “To safeguard the data of Philippine passport holders and prevent future breaches, it’s essential to implement blockchain solutions like Certihash’s Sentinel Node, combined with advanced cybersecurity practices. This would form a comprehensive, multi-layered defense capable of preventing breaches while fostering a stronger relationship of trust between the government and its citizens,” he said.
Blockchain's advantages over traditional cybersecurity
For large-scale government databases, blockchain presents unique benefits over traditional cybersecurity systems. “Cybersecurity will always play a role,” Navalan noted, but blockchain's decentralized nature eliminates intermediaries, which reduces potential attack vectors. The immutable record of all transactions is another layer of protection, allowing data to be monitored publicly or anonymously.
Navalan stressed that blockchain's traceability also aids in combating cybercrime. Creating a verifiable trail of all actions makes it easier for ethical hackers and security professionals to trace unauthorized transactions and hold malicious actors accountable.
Blockchain for data breach transparency
One persistent issue in data management is the lack of transparency when breaches occur. Blockchain could change that by allowing real-time monitoring of data access. Navalan pointed out that blockchain's public ledger makes it harder for third-party vendors or government agencies to hide breaches. “Depending on the blockchain
