Benefits of Blockchain To Enhance Data Security


Blockchain provides security for organizations by ensuring trust, privacy, secure communication, decentralization and integrity.

Due to its ability to provide transparency, immutability, and decentralized storage of data, applications using blockchain for data security can soon replace existing technologies that provide centralized storage.

Although experimentation and innovation can enable businesses to use blockchain in a broad range of applications, the use of blockchain for data security seems to be the most obvious application area. Blockchain, which is synonymous with privacy, is being considered for a myriad of applications that require the storage of data in a securely encrypted and easily retrievable manner. Blockchain provides numerous benefits over traditional data security technologies, four of which are listed below:

Blockchain & Data Security

1. Formation of Trusted Partnerships

Blockchain provides a decentralized, transparent database that ensures trust between network participants. The participants can be partners in a supply chain or businesses in a consortium, who use blockchain to record transactional data and other shared information. Due to the blockchain’s democratization of control, it enables all participants to have equal access to the stored data and seeks consensus from all participants before approving any change. This decentralized trust model can enable the formation of secure ecosystems that groups of companies can use for storing and sharing data.

2. Assurance of Individual Privacy

There has been a misconception among the public and the business community regarding the compatibility of blockchain with the recently passed General Data Protection Regulation (GDPR). The perceived incompatibility is due to the competing nature of blockchain which is essentially immutable with GDPR, which requires organizations to erase private data upon the owner’s request. Blockchain permanently stores older blocks of data to maintain an unalterable series of records and transactions. This ensures that the provenance of every new block can be verified and traced back throughout the chain’s history. GDPR requires the erasure of personal data when requested by the individual, which, theoretically, blockchain does not allow. However, designing a GDPR-compliant blockchain is possible and multiple methods are being devised to achieve that. This can enable the use of blockchains to store anonymized data, such as customer records through hashing and tokenization.

3. Maintenance of Data Veracity

Data integrity is a foundational property of data stored on the blockchain. Accessing and modifying the data stored on the blockchain is nearly impossible without notifying and seeking consensus from the entire network. Thus, blockchain can be used as the source of truth by participants and drive a secure ecosystem that can function in a trustless manner, i.e., without requiring any trust or even familiarity with the other party.

4. Prevention of Data Loss

Traditional data storage and security systems are highly centralized, which means they have a single point of failure. This implies that any external attack on the central server like malware or brute-force hacking attempts may lead to partial or total loss of stored data. Depending on the type of data stored on the system, the consequences of data loss can be devastating for businesses and even economies. Blockchain-powered storage is highly resilient to hacking and other forms of external attacks. Since the same data is stored on all the nodes on a blockchain, there is minimal to no risk of data loss. This means that blockchain-based data security and storage are highly suited for the storage of vital information, such as financial transactions and customer identities.

Although the use of blockchain in data security systems seems much more beneficial than the use of traditional technologies, there are a few significant challenges associated with blockchain that need addressing before the transition. Business leaders should not be intimidated by these challenges, but be motivated by the potential business value that can be achieved, and should push for gradual adoption of the technology.

Which Subscriptions are Brits Cancelling this Year?


A new study from online data experts at VPN Overview has revealed which popular online subscription services are most likely to be cancelled this year.

Använder sig av Google search data, the study analysed the number of searches around cancellations. 

The data revealed, “Cancel Amazon Prime” has received the most searches in the last 12 months, with 232,540 on average. 

As the cost of living continues to soar, new research shows Brits are sacrificing their online subscriptions in a bid to spara pengar.

Recent studies show the average household spends £41.70 on online subscriptions each month in 2022, however, with services such as Amazon Prime hiking their prices, it’s no surprise to find that an increasing number of Brits are trying to cancel.

To find out more, online data experts from VPN Overview analysed Google search data to reveal which subscription services are receiving the highest number of searches around cancellations.

Comparing searches YOY from 21 to 22, the data also reveals which subscriptions have received the highest percentage increase overall.

With 232,540 Google searches in the last 12 months, Amazon Prime is the subscription service most likely to be axed by Brits, followed by Spotify which received 220,340 searches overall.

Both streaming services have recently hiked their prices; Amazon Prime in September, when monthly prices jumped from £7.99 to £8.99, and Spotify at the end of 2021 when family accounts increased from £12.99 to £13.99. It’s also been reported that Spotify are planning a further increase at the end of this year.

Sky TV is next on the list with 163,340 searches around cancellations. An all-inclusive Sky TV package comes in at £110.00 per month, which is no doubt a high price to pay during the cost-of-living crisis.

In fifth place comes Netflix (163,340 searches), followed by Audible, an Amazon-owned platform for audiobooks

Further down the list, queries such as ‘cancel Now TV’ and ‘how to cancel Now TV’ have received 91, 220 UK searches, whilst Amazon Music has received 70.080 and Disney Plus tallied up 49,090.

Which search terms have the highest YOY increase in 2022?

Alongside annual searches, the study also analysed which online subscriptions have the highest YOY increase, suggesting a further surge of cancellations this year.

Sky TV has seen the biggest increase in searches around how to cancel, with the data revealing a 40.53% surge YOY.

This is followed by Apple TV with a 37.25% increase and Netflix with 35.44%. Spotify isn’t far behind with searches for ‘cancel Spotify’ increasing by 31.82%.

Live and on-demand sports streaming platform, Dazn, also makes the list with a 19.05% increase along with BT Sport (18.35%).

Finally, Brits are saying goodbye to Discovery plus, which has seen an increase of 15.97% and Britbox with an increase of 4.72%.

A spokesperson from VPN Overview commented: “It’s interesting to see such a high number of searches around cancelling subscription services which are often part of our daily lives. However, as the cost of living continues to rise and these services hike their prices, it’s no surprise to see people sacrificing their premium packages.”
