How to Keep the ML Datasets Secure?

On average, it takes 50 days to discover and report a data breach. During that time, businesses risk significant harm, including unauthorized access, financial losses, and reputational damage.

Ensuring data privacy regulations are followed can be tough when labeling personal data. You need systems that keep the data private by not letting people directly interact with it.

How to De-Risk Yourself from Legal Issues with Private Data

To avoid legal headaches with private data, getting consent upfront from those who generate the raw data is essential for ethical data labeling in ML projects. This builds trust and ensures compliance with data privacy regulations.

What happens when data is used without consent

Using data without consent can have a number of negative consequences. Perhaps the most significant is the erosion of user trust. When individuals feel their data has been misused, they’re less likely to share information in the future, hindering the development of AI and other data-driven technologies.

Additionally, data breaches can expose personal information, leading to identity theft, fraud, and even physical harm. Legal repercussions are also a concern. Data privacy regulations around the world are becoming increasingly strict, and organizations that fail to obtain proper consent can face hefty fines. In the worst-case scenario, misuse of data can perpetuate discrimination or bias, leading to unfair and unethical outcomes.

What are the examples of raw data

Raw data encompasses any unprocessed information collected from various sources. Here are some common examples you might encounter in data labeling projects:

• Text data: This includes emails, social media posts, documents, and chat logs. Text labeling tasks often involve sentiment analysis, topic classification, or information extraction.

• Images and videos: This can be any visual data you’re working with for training computer vision models. Labeling tasks for this type of data could involve object detection, image segmentation, or scene classification.

• Sensor data: Data collected from sensors can include temperature readings, GPS coordinates, or audio recordings. Sensor data labeling can be used for tasks like anomaly detection, activity recognition, or machine calibration.

• Audio data: Music, speech, environmental sounds, or animal sounds are some of the examples of audio data. Speech recognition and sentiment analysis are common types of labeling tasks used for applications like automatic transcription services, music recommendation systems, and real-time voice translation tools.

How to ask consent from users

Obtaining user consent for data collection and labeling is crucial for ethical and legal reasons. Here are some key principles to follow:

• Transparency: Clearly inform users about what data is being collected, how it will be used, and who will have access to it.

• Granularity: Provide options for users to choose the specific types of data they’re comfortable sharing.

• Control: Allow users to withdraw their consent at any time and offer an easy way for them to access or delete their data.

• Clear language: Use concise and easy-to-understand language in your consent forms, avoiding technical jargon.

• No dark patterns: Here are the things to avoid when you want to ensure that user consent is truly informed, freely given, and reflects a clear understanding of how their data will be used:

  • Pre-checked boxes: Don’t pre-check consent boxes. Users should actively opt-in to share their data.

  • Forced choices: Don’t force users to agree to data collection as a condition of service use. Provide a clear “opt-out” option.

  • Confusing language: Avoid burying consent requests within lengthy terms and conditions. Present consent information prominently and separately.

  • Privacy nudges: Don’t use misleading wording or pressure tactics to sway users towards giving consent.

By following these guidelines, you can ensure that your data labeling projects are conducted in a way that respects user privacy and builds trust.

Data Security vs. Data Privacy

Data labeling security and privacy are related but different concepts. Data security focuses on protecting electronic information from unauthorized access, while data privacy concerns individuals’ rights to control how their personal data is collected and used.

As businesses increasingly use AI and ML technologies, the importance of data security has grown. Moreover, there are compliance issues related to data privacy that require careful consideration. Training data, which might include sensitive personal information like names, addresses, and birthdates, carries risks if mishandled, potentially leading to identity theft, fraud, or other malicious actions.

The reason these two concepts are often intertwined is that they both revolve around data protection. Besides, the link between data privacy and data security in annotation has become stronger due to the rise of regulatory frameworks such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

Data Privacy Protection Laws

It’s important to process private data according to data laws. Today, over 120 countries have enacted international data protection laws to better safeguard their citizens’ data.

Here’s a list of the global data privacy regulations to consider when labeling ML datasets or outsourcing to the vendor:

• GDPR (General Data Protection Regulation): The most extensive data protection and privacy regulation so far is the General Data Protection Regulation (GDPR), introduced in 2018 in the European Union and the European Economic Area. According to GDPR, people have the right to know how their information is being handled and to have more control over their data online.

  Applies to the European Union (EU) and regulates how personal data of EU residents is processed by any organization, regardless of location. It emphasizes transparency, individual control, and data security.

  Key aspects include:

  • Individual Rights: EU residents have rights to access, rectify, erase, and restrict processing of their data.

  • Lawful Basis for Processing: Organizations need a legal justification for collecting and using personal data.

  • Data Breach Notification: Data breaches must be reported to authorities and affected individuals.

• HIPAA (Health Insurance Portability and Accountability Act): Applies to the United States and safeguards protected health information (PHI) of patients. It focuses on securing medical records and ensuring they are used only for authorized purposes.

  Key aspects include:

  • Covered Entities: Applies to healthcare providers, health plans, and healthcare clearinghouses.

  • Minimum Necessary Standard: PHI should only be used to the minimum extent necessary for the purpose.

  • Patient Rights: Patients have rights to access, amend, and request an accounting of disclosures of their PHI.

• CCPA (California Consumer Privacy Act): While HIPAA focuses on protecting individuals’ medical records and personal health information, while CCPA aims to enhance privacy rights and consumer protection for residents of California by regulating the collection and use of personal data by businesses.

  CCPA empowers California residents with control over their personal data. It grants rights to know, access, delete, and opt-out of data sales. Businesses must provide clear privacy notices and respond to consumer requests. The CCPA focuses on data sales and has exemptions, but it paved the way for stronger data privacy protections in California and beyond.

• ISO 27001 (International Organization for Standardization): Not a law, but an internationally recognized standard for information security management systems (ISMS). It provides a framework for organizations to implement best practices for data security.

  ISO 27001 is a global framework for managing information security in a company. Getting certified means your Information Security Management System meets international standards, assuring customers about your system’s security. Certification involves evaluating your organization against 114 requirements across 14 security categories. While not specific to privacy, achieving ISO 27001 certification demonstrates a commitment to robust data security practices, which can be helpful for GDPR or HIPAA compliance.

When partnering with a data labeling company, both parties need to establish an agreement that outlines specific labeling details: confidentiality, compliance with laws and regulations, and the deletion or return of data after processing ends.

How to Organize Data Annotation Without Data Leaks

Even with user consent, a data leak during annotation can be a PR disaster. To prove our point, let’s take a look at the recent case with Amazon.

Amazon Ring Case

Ring, the video doorbell company owned by Amazon, has settled a lawsuit in 2023 with the US Federal Trade Commission (FTC) for $5.8 million over allegations that employees had improper access to customer videos. The FTC claimed Ring employees had unrestricted access to all customer videos and could download or share them, while Ring maintained the data was encrypted and access was restricted for customer privacy. The settlement required Ring to implement a data security program and disclose employee data access procedures.

This case highlights the importance of data security and privacy regulations in data labeling, especially when dealing with sensitive data. Data labeling often involves human oversight. In the Ring case, the concern was Ring employees potentially having unfettered access to user videos used for training facial recognition or motion detection. Therefore, it’s crucial for data labeling companies to ensure secure storage and access controls to mitigate privacy risks.

For instance, data privacy regulations like the GDPR and CCPA would require limitations on such access. These regulations mandate user consent for data collection and usage, and restrict the retention and distribution of personal data. This can also involve data anonymization techniques to minimize the amount of personally identifiable information (PII) used in labeling.

Best Practices for Keeping Data Secure

Data quality is critical, with inconsistent collection standards (50%) being the top concern, followed by compliance (48%) and data access (44%). Hence, your data labeling process must adhere to relevant regulatory standards and security levels required for the data. It should provide a secure environment equipped with appropriate training, policies, and procedures to ensure compliance and data integrity.

The key factors to consider for secure data labeling process include:

Annotators security:

Ensure that all annotators have undergone background checks and have signed non-disclosure agreements (NDAs) or similar documents outlining your expectations for data security. Managers should closely monitor compliance with these data security protocols.

Device control:

Annotators should surrender any personal devices, such as mobile phones or external drives, upon entering the workplace. The service provider should also disable any features on work devices that could allow data downloading or storage.

Workspace security:

Workers should conduct their tasks in a location where their computer screens are not visible to individuals who do not meet the specific data security requirements for your project.

Infrastructure:

Use an appropriate labeling tool based on your unique needs and security standards, ensuring it offers robust access controls and encryption to safeguard sensitive data.
