You think you are anonymous on the internet? Well, not when there is what is called De-Anonymization.
So they promise you that your profile and identity is safe while you register on social media platforms, but somehow some of these platforms De-Anonymize your identity rendering your internet Anonymity all but a farce.
Remember that time Facebook were in trouble with the US government when word got out it was sharing its users data to a data based company to help understand their likely voting patterns? The incident placed its founder, Mark Zuckerberg on the edge till the case was eventually resolved in a parliamentary hearing.
Since then, some users have become quite wary of what they share online, bearing in mind the popular saying ‘anything you say or do can be used against you…’, as in the internet setting, it is very much a possibility.
Your data can be studied and sold to the highest bidder as data collection is large a big business in the scheme of things for some companies, in essence there very well is little privacy on the internet for anyone concerned about their anonymity.
So if you are of the illusion that you cannot be identified with things you post or share on the internet, you need to come off it if you don’t put extra measures to keep your identity private.
This brings to the general topic of De-Anonymization, what really is it?
It is a concocted term that stands for data re-identification whereby it involves the cross referencing of anonymous data with already available information to unearth the true identity of an individual that may on a normal day wish to remain anonymous.
Anonymized data describes any data about someone who is very reluctant to share any of their personal information on the internet although through their activity, some private data is shared with a specific platform. The anonymity of the data lies on the trust that such platform would not share such details to a third party.
De-Anonymization comes into play when such data is sold and the third party gets to cross reference other details about such data through other means to uncover all there is about the individual or group.
These things often leave internet users vulnerable to blackmail schemes or scam artists who could use their data for nefarious purposes for gains.
So how can users protect their details from being De-Anonymized by cyber actors in the game?
There is no specific rule in this game considering each day the cyber world comes up with new updates to counter present features, in essence however the user tries to mask their identity, the cyber world is always a step ahead.
Although, that shouldn’t make the user all doom and gloomy about using the internet considering they still stand a chance to ward off these actors by playing safe with the use of secure and private based browsers. There is also the fact they need to have an anti-malware protection installed on their browsers.
Another way users can protect themselves is by reading through the Terms and Policy of applications they intend to install on their devices to know what is applicable or not.
Most times we are too eager to tick the agree box while using the internet that websites or platforms are confident they can get us to agree to terms that reveals whatever confidential information we may have shared with them.
A user dedicating their time to knowing what they are signing up to would be better protection in future cases where their data may be sold behind their knowledge.
There is also the safest option for users, which is very much to share nothing about their privacy online that may ultimately come back to bite them or be used against them.

Data Warehousing and Data Management Cost Optimization
In this article, we will discuss the key aspects of data warehousing and management cost optimization and best practices established through studies.
Data warehousing and management is a crucial aspect of any organization, as it helps to store, manage, and analyze vast amounts of data generated every day. With the exponential growth of data, it has become imperative to implement cost-effective solutions for data warehousing and management.
Understanding Data Warehousing and Management
Data warehousing is a process of collecting, storing, and analyzing large amounts of data from multiple sources to support business decision-making. The data stored in the warehouse is organized and optimized to allow for fast querying and analysis. On the other hand, data management involves the processes and policies used to ensure the data stored in the warehouse is accurate, consistent, and accessible.
Why is Cost Optimization Important?
Data warehousing and management costs can add up quickly, making it essential to optimize costs. Implementing cost-optimization strategies not only reduces financial burden but also ensures that the data warehousing and management system remains efficient and effective.
Cost optimization is important for data warehousing and management for several reasons:
Financial Benefits: Data warehousing and management can be expensive, and cost optimization strategies can help reduce these costs, thereby increasing the overall financial efficiency of the organization.
Improved Performance: Cost optimization strategies, such as data compression, data archiving, and data indexing, can help improve the performance of the data warehousing and management system, thereby reducing the time and effort required to manage the data.
Scalability: Implementing cost-optimization strategies can help to scale the data warehousing and management system to accommodate increasing amounts of data, without incurring significant additional costs.
Improved Data Quality: By implementing cost-optimization strategies, such as data de-duplication and data partitioning, the quality of the data stored in the warehouse can be improved, which can lead to better decision-making.
Overall, cost optimization is important for data warehousing and management as it helps to reduce costs, improve performance, and maintain the quality of the data stored in the warehouse.
Established Cost Optimization Strategies
Scalable Infrastructure: It is important to implement a scalable infrastructure that can handle increasing amounts of data without incurring significant costs. This can be achieved through cloud computing solutions or using a combination of on-premises and cloud-based solutions.
Data Compression: Data compression can significantly reduce the amount of storage required for data, thus reducing costs. There are various compression techniques available, including lossless and lossy compression, which can be used depending on the type of data being stored.
Data Archiving: Data archiving is the process of moving data that is no longer actively used to cheaper storage options. This helps to reduce the cost of storing data while ensuring that the data remains accessible.
Data de-duplication identifies and removes duplicate data from the warehouse. This helps to reduce storage costs and improve the overall performance of the data warehousing system. Data de-duplication is a cost optimization strategy for data warehousing and management that focuses on identifying and removing duplicate data from the warehouse. This is important for several reasons:
Reduced Storage Costs: Duplicate data takes up valuable storage space, which can be expensive. By removing duplicates, the storage requirements for the data warehouse can be reduced, thereby reducing storage costs.
Improved Data Quality: Duplicate data can lead to confusion and errors in decision-making, as it may not be clear which version of the data is accurate. By removing duplicates, the quality of the data stored in the warehouse can be improved, which can lead to better decision-making.
Improved Performance: The presence of duplicate data can slow down the performance of the data warehousing system, as it takes longer to search for and retrieve the desired data. By removing duplicates, the performance of the data warehousing system can be improved, reducing the time and effort required to manage the data.
Increased Security: Duplicate data can pose a security risk, as it may contain sensitive information that can be accessed by unauthorized individuals. By removing duplicates, the security of the data stored in the warehouse can be increased.
Overall, data de-duplication is an important cost optimization strategy for data warehousing and management, as it helps to reduce storage costs, improve data quality, improve performance, and increase security. It is important to implement an effective data de-duplication solution to ensure the success of this strategy.
Data Partitioning: Data partitioning involves dividing the data into smaller, manageable chunks, making it easier to manage and analyze. This helps to reduce the cost of storing and processing large amounts of data.
Data Indexing: Data indexing is the process of creating an index of the data stored in the warehouse to allow for fast querying and analysis. This helps to improve the performance of the data warehousing system while reducing costs.
Automation: Automating data warehousing and management processes can significantly reduce the cost and effort required to manage the data. This includes automating data extraction, transformation, loading, and backup processes.
In conclusion, data warehousing and management cost optimization is a crucial aspect of any organization. Implementing cost-optimization strategies, such as scalable infrastructure, data compression, data archiving, data de-duplication, data partitioning, data indexing, and automation, can significantly reduce the cost of data warehousing and management while ensuring that the system remains efficient and effective.
It is important to keep in mind that the specific cost-optimization strategies used will depend on the unique needs and requirements of each organization.
Overview of big data security and privacy
Big data security and privacy are crucial considerations in the era of large-scale data collection and analysis. The security of big data refers to the measures taken to protect data from unauthorized access, theft, or damage. Privacy, on the other hand, refers to the protection of sensitive and personal information from being disclosed to unauthorized parties.
To ensure the security of big data, organizations adopt various measures such as encryption, access control, network security, data backup and recovery, and others. Additionally, they may also implement compliance with security standards and regulations such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).
However, the increased use of cloud-based big data solutions and the rise of the Internet of Things (IoT) have brought new challenges to the security and privacy of big data. To mitigate these challenges, organizations are using technologies such as blockchain, homomorphic encryption, and differential privacy to provide stronger privacy and security guarantees.
In conclusion, big data security and privacy are crucial components of the big data landscape. Organizations must implement robust measures and technologies to protect sensitive and personal information, maintain the security of big data, and comply with relevant security regulations.
