What are the steps to developing a data privacy strategy for data architecture?

Crafting a data privacy strategy for your data architecture commences with pinpointing clear data privacy goals. Define what sensitive information requires protection and the level of security needed. Consider compliance with regulations like GDPR or HIPAA. These goals serve as the compass for structuring your architecture, data access controls, and encryption methods, ensuring that privacy remains at the forefront of your data management practices.

Data Privacy is directly co-related to Customer trust. Privacy breach is very costly and brings bad reputation to Organization. Most of Governments and Domains have Privacy specifications well documented. It will be good starting point to know which of them are applicable to the data asset. Risk minimization is important. Document and store only necessary information. Identify/classify key PII or critical data elements early. Have anonymization/encryption strategy attached to Roles. Define Authorization and Authentication at lowest grain. Its very critical to know end to end linage of PII datasets and controlling the flow. It will prevent possible misplacing data in wrong hands. And the end, respect customer's right to forget!

Developing a data privacy strategy for data architecture is crucial. Follow these steps to ensure the data privacy: 1. Data Classification: Categorize data by sensitivity. 2. Access Control: Implement strict permissions. 3. Encryption: Protect data at rest and in transit. 4. Data Governance: Define handling and retention policies. 5. Compliance: Stay updated with regulations. 6. Monitoring and Auditing: Regularly monitor data access. 7. Data Breach Response Plan: Be prepared to respond to breaches.

Data privacy and protection, unlike other Data governance domains, requires understanding of local (and global if company’s data is moving out of country’s boundaries) legal laws and regulations. So it is less technical and more of legal exercise. Data privacy team should have a legal advisor, to advise / prepare the documents (consent form, Data sharing agreement etc)

Data Privacy is very important and its critical to ensure compliance with regulations. - Create an inventory of all the data your organization collects, processes, and stores. - Understand how data is collected, processed, and shared. - Ensure that only authorized personnel can access and process sensitive data. - Communicate your data privacy practices to customers, employees, and stakeholders to build trust and transparency. - Get advice from legal and privacy expertise to ensure that your data privacy strategy aligns with legal requirements.

Privacy Ops is a great concept in this space coined the term by Securi.ai to automate compliance with privacy regulations and be responsible custodians of people's data. Privacy_ops focuses on Data Privacy Laws, Privacy practices, and the technologies. Privacy-Ops provides an assessment option to give visibility into an organization's privacy law compliance such as requirements under the GDPR, CCPA, LGPD, and more. Other areas to focus on customer touch-point graphs to detect and classify sensitive / personal data across various business lines, data domains, data types and infrastructures. As we are now in the age of AI, privacy-preserved computation and computation disclosures are other areas to emphasis in order to building the data trust

Utilizing frameworks like the Data Privacy Maturity Model (DPMM) or tools like the Data Privacy Scorecard (DPS) offers a structured and comprehensive way to evaluate your existing data privacy policies and practices. It's like taking a health checkup for your data privacy efforts.

Some organization encounters data security and privacy as stage during data strategy maturity assessment. Guide to asses current state of data privacy starts from: 1. Understanding current practises 2. Gaps analysis with regulatory requirements 3. Classify metadata and attributes, data domains etc

Take a risk-based approach to regularly evaluate data privacy policies, controls, and practices against regulations and peer benchmarks to understand strengths, gaps, and opportunities to mature capabilities aligned to sensitive data types and emerging use cases.

In my experience, Evaluate your current state of data privacy readiness. This involves a comprehensive examination of your existing policies, practices, and technologies. Assess your organization’s level of awareness and preparedness regarding data privacy. Consider whether you have defined processes for data handling, incident response, and data subject requests. Identify gaps and areas where your data privacy measures can be improved. A maturity assessment helps you understand where you stand and where you need to focus your efforts to enhance data protection.

1. Data classification and labeling. 2. Access control and encryption. 3. Data retention and deletion policies. 4. Monitoring, training, and governance.

There are various data privacy goals and objectives that need to be taken into consideration. Firstly, it is important to identify and create a link between the privacy-related organisational goals and the data protection process. This includes the right to privacy and to data protection, as well as the need to identify and analyse how data privacy might be affected by new techs. Additionally, large amounts of data should be collected and analysed in order to identify potential correlations. Big Data is also a key part of this process, and is used to achieve the goal of harmonizing data privacy frameworks. Furthermore, the merits and shortcomings of the data protection principles and elements should be highlighted to identify any risks.

Data Dictionary per Database, Flat File, API, Report, Machine Model Datasets listing the attributes: Sensitive Indicator Personifiable Indicator Consented Indicator Derivations of sensitive/personifiable attributes that are not consented i.e pseudonymisation, anonymisation, one way hash. This will support the Data Privacy team's approve approval of data usage in analytical techniques along with storage and access.

A privacy-preserved, multi-party collaboration is one key data privacy area to consider where different parties collaborate as an eco-system. Example is a Machine Learning collaboration between hospitals, insurance providers, health-care service providers, customers, patients and other parties to share their privacy data without compromising the data privacy. Technologies like Confidential Computing with Trusted Execution Environments (TEE) [Intel SGX, TDX etc] are great example technologies to consider.

Translate privacy goals into measurable requirements for notice, consent, access, data minimization, retention, security, and governance to embed privacy protections aligned to risk levels across the data lifecycle from collection and storage to processing, sharing, and deletion.

In my view, Develop a comprehensive data privacy architecture that aligns with your defined requirements. This architecture encompasses the technical and procedural elements necessary to protect data. It should include data encryption strategies, data masking techniques, role-based access controls, and audit mechanisms. Consider data governance principles, data classification, and incident response plans. Embrace architectural concepts such as defense in depth and privacy by design, ensuring that data protection is woven into every layer of your architecture.

In my experience, a good point to start is finding technologies that support all business needs. For example, in cloud environments, one the first decisions is about which encryption mechanism is the best fit to protect unauthorized access to the data. Carrying on, another point is about data compliance, it is necessary to protect how data is available for users, creating an process to management which portion of this data is sharing and a complete governance tool to management all of this.

Developing a data privacy strategy for data architecture requires a methodical approach, starting with a thorough understanding of the data landscape. The steps include -Classifying data based on sensitivity -Assessing privacy risks and vulnerabilities -Implementing robust encryption and access controls -Complying with relevant regulations, and -Establishing ongoing monitoring and auditing processes. When designing data privacy architecture, it's essential to think about how valuable your data is, what kind of risks it might face, and the rules you need to follow. This way, you can build safeguards right from the beginning to protect important information and use it safely within your organisation.

Designing a data privacy architecture involves understanding the regulatory landscape, data inventory & classification, embed privacy by design, data access controls like RBAC or ABAC and using privacy enhancing techniques across organization.

Intel SGX, TDX embraces Confidential Computing and allows to protect "Data in Use" through a Trusted Envelope and Trusted Execution Environment (TEE) architecture. Homomorphic Encryption is another emerging technology addresses the multi-party, privacy preserved computation architecture. Some other paradigms to follow to enforce data privacy are Clean Room (Google Cloud), Data Zone (AWS) concepts made available through the respective hyperscalers.

If you have seen my comment above, this tends to be the easiest of the steps. Your tools should help you do this, and if they don't, then find a tool to help you either achieve this by complimenting your existing infrastructure or replace what is not meeting your needs. Don't be scared of this step at all.

In my experience, The implementation phase involves putting your designed data privacy architecture into practice. This may entail deploying encryption technologies, setting up identity and access management solutions, and establishing robust monitoring and auditing systems. Employee training and awareness programs are essential during this phase to ensure that your staff follows data privacy policies and best practices. Implementation should closely align with your defined data privacy requirements to maintain a consistent and effective data protection framework.

Die Umsetzung von Sicherheitsmaßnahmen wie die Anonymisierung und Verschlüsselung von Daten ist prädestiniert für Fehler, die zu schwerwiegenden Datenschutzverstößen führen können. Bei der Verschlüsselung sollte auf den Einsatz etablierter Bibliotheken und als sicher geltender Konstruktionen geachtet werden. Die ordentliche Ablage des Schlüsselmaterials ist ebenfalls wesentlich. Bei der Anonymisierung muss darauf geachtet werden, dass die Daten durch Korrelationen nicht wieder deanonymisiert werden können. Das kann u.a. passieren, wenn zu kleine Personengruppen aus den Daten ermittelt und anschließend durch Prüfung weiterer Faktoren Rückschlüsse auf Einzelpersonen gezogen werden können.

In my experience, this is something challenging to do on your own. I have worked with Gartner, completing assessments to understand who we were and comparing ourselves with other companies in a similar situation. To do this properly, look for an independent third party to help you and see where you are compared to others in your industry.

Also as part of data privacy architecture need to include aspects of 1. Data Lineage across 2. Ability to absorb new changes as regulations keep changing for better 3. Ease of adoption from business perspective 4. Data localisation With renewed approach from nations on data privacy data localisation is becoming new norm and this need to be seamless with metadata designs and modelling need to consider these aspects as well.

While desiging data architecture and incorporating data privacy, first thing that needs to be taken into account is data classification and then deciding the approaches, tools and techniques that should align with data compliance or policies like Personal Data Protection Law.

Genauso wie beim Informationsmanagement kann auch beim Datenschutzmanagement der klassische PDCA-Cycle angewendet werden. Aufgrund der ständigen Veränderung der unternehmensinternen Datenverarbeitungen bedarf es einer kontinuierlichen Kontrolle und Anpassung der eigenen Datenschutzmaßnahmen.

1. Data Lifecycle Management: Manage data from creation to deletion, ensuring proper handling at every stage to minimize privacy risks. 2. Cross-Border Data Transfer: If operating globally, comply with regulations for international data transfers to protect privacy. 3. Third-Party Risk Management: Evaluate and manage privacy practices of external partners to prevent potential vulnerabilities. 4. Privacy Impact Assessments (PIA): Regularly assess projects and technologies for potential privacy risks to proactively prevent issues. 5. User Empowerment: Give users control over their data with transparent communication and easy-to-use tools for access and preferences.
