    CONTROL QUESTION: Why is big data different from any other data that you have dealt with in the past?

    Big Hairy Audacious Goal (BHAG) for 10 years from now:

    In 10 years, my goal for data masking in big data is to have developed a comprehensive and automated system that effectively ensures the protection of all sensitive information in large-scale data sets. This system would not only mask individual data points, but also apply advanced techniques such as differential privacy, homomorphic encryption, and secure multi-party computation to preserve the integrity of the data while still allowing for accurate and meaningful analysis.

    This big, hairy, audacious goal (BHAG) will be essential in addressing the unique challenges posed by big data. Unlike traditional data sets, big data is characterized by its volume, variety, and velocity. Traditional data masking techniques are often not effective or feasible in this context, as they rely on manual or static processes that cannot keep up with the constant influx of data.

    Moreover, big data is usually collected from multiple sources and may contain sensitive information that needs to be protected, such as personally identifiable information (PII), financial data, or intellectual property. This further complicates the task of data masking, as the system must be able to handle a diverse range of data types and adhere to various compliance regulations.

    Additionally, big data is often used for complex and advanced analytics, such as machine learning and artificial intelligence, which can uncover hidden insights and patterns in the data. As a result, any errors or gaps in data masking could lead to compromised privacy and security, as well as inaccurate conclusions and decisions being made based on the data.

    To overcome these challenges, my BHAG for data masking in big data includes building a robust and adaptable platform that can seamlessly integrate with existing big data tools and systems. It would also incorporate advanced algorithms and machine learning capabilities to automate the data masking process and improve its effectiveness over time.

    With this goal, I envision a future where data privacy and security are no longer barriers to leveraging the full potential of big data. Organizations will be able to confidently collect, store, and analyze large amounts of data without compromising the sensitive information within it. This BHAG will not only benefit businesses, but also society as a whole, by promoting the responsible and ethical use of big data for the betterment of humanity.

    Data Masking In Big Data Case Study/Use Case example – How to use:


    The proliferation of data in recent years has led to the rise of big data, which refers to the large volumes of structured and unstructured data that organizations collect and process on a daily basis. This data comes from various sources such as social media, internet browsing activity, mobile devices, and sensors, among others. The abundant availability of big data has opened up new opportunities for businesses to gain insights, make informed decisions, and improve their operations. However, with great data comes great responsibility, as organizations must ensure the security and privacy of this data to comply with regulations and protect sensitive information. This is where data masking comes into play. Data masking, also known as data obfuscation, is a technique used to anonymize or scramble sensitive information in big data environments, making it unreadable to unauthorized users while preserving its analytical value. In this case study, we will explore the importance of data masking in big data and how it differs from traditional data management practices.

    Client Situation:

    ABC Corporation is a global e-commerce company that handles large amounts of customer data on a daily basis. The company operates in multiple countries, which requires them to adhere to different data protection laws and regulations, such as GDPR and CCPA. ABC Corporation’s database contains personal information, including names, addresses, credit card numbers, and purchase history of millions of customers. They were facing challenges in securing their big data environment due to the diverse nature of their data and the increasing threat of cyberattacks. Furthermore, they were concerned about maintaining compliance with data privacy regulations and avoiding potential financial and reputational damage.

    Consulting Methodology:

    To address the client’s concerns, our consulting firm utilized a three-part methodology: discovery, analysis, and implementation.

    Discovery: The first step was to analyze ABC Corporation’s data architecture and understand their data flow, storage systems, and data security protocols. We conducted interviews with key stakeholders to identify their data privacy requirements and legal obligations.

    Analysis: Based on the information gathered during the discovery phase, we performed a detailed risk assessment to identify potential vulnerabilities in the big data environment. We also assessed the impact of data masking on the analytical value of the data.

    Implementation: In the final phase, we implemented a data masking solution that incorporated best practices from industry standards and compliance regulations. The solution was customized to meet ABC Corporation’s specific needs and integrated with their existing data management systems.


    As a result of our engagement, the following deliverables were provided to ABC Corporation:

    1. Risk assessment report: A comprehensive report detailing the findings of our risk assessment, including identified vulnerabilities, potential impact, and recommended solutions.

    2. Data masking strategy: A customized data masking strategy tailored to meet the specific needs and requirements of ABC Corporation. The strategy included a data inventory, masking techniques, and defined roles and responsibilities for managing and monitoring the data.

    3. Implementation plan: A detailed plan outlining the steps and timeline for implementing the data masking solution.

    4. Data governance framework: A framework for governing data privacy and security policies, procedures, and controls.

    Implementation Challenges:

    ABC Corporation faced several challenges during the implementation of the data masking solution, including:

    1. Finding a balance between data security and analytical value: The main challenge was to mask sensitive data without compromising its analytical value. This required careful consideration of the data masking techniques used and the extent to which data was masked.

    2. Identifying all sensitive data: With large volumes of data, it was challenging to identify and categorize all sensitive data within the organization. This required collaboration with multiple departments and data owners.

    3. Integrating with existing systems: The data masking solution needed to seamlessly integrate with ABC Corporation’s existing data management systems, which required thorough testing and troubleshooting.

    Key Performance Indicators (KPIs):

    To measure the success of the data masking implementation, the following KPIs were defined:

    1. Number of successful data breaches: A decrease in the number of successful data breaches would indicate the effectiveness of the data masking solution in protecting sensitive data.

    2. Compliance with data privacy regulations: The company’s compliance with different data privacy regulations, such as GDPR and CCPA, was measured to ensure adherence to legal requirements.

    3. Analytical value of the data: A key KPI was to ensure that the analytical value of the data was preserved after data masking. This was measured through data quality and analytics performance metrics.

    Management Considerations:

    Data masking in big data environments requires a holistic approach, involving all stakeholders, including IT, legal, and business teams. Organizations must have clear data governance procedures in place, along with continuous monitoring of data privacy policies and regulations. It is also crucial to regularly assess and update the data masking techniques used to stay ahead of evolving security threats.


    In conclusion, big data presents unique challenges for organizations in terms of data management and security due to its volume, velocity, and variety. Data masking provides a layer of protection for sensitive data in big data environments, enabling organizations to comply with regulations, avoid data breaches, and protect their reputation. Our consulting firm helped ABC Corporation overcome their data security challenges by implementing a data masking solution that maintained data privacy and protected their sensitive data while preserving its analytical value. With proper implementation and management, data masking can be an effective solution for securing big data environments.
