Study Notes
IT Law Fundamentals
- EU jurisdictions require additional conditions for processing communication content in sensitive situations (e.g., explicit authorization from Privacy Authorities for processing healthcare data).
- Businesses seek to collect more personal data for business opportunities.
- Users demand higher privacy protection due to pervasive IT use, potentially endangering data confidentiality (digitalization of privacy).
- Disagreements arise regarding appropriate levels of data protection.
Data Protection and Surveillance of Shared Data
- It's unclear under which law shared data and information are protected when used with IT devices.
- Factors considered include:
- The law of the client's location.
- The user's national law.
- The law of the company managing the digital device.
- The law of the server location.
- Optional legislation in data/information insertion processes.
Conflicting Data Protection Rules
- Conflicting rules in various countries generate data collection and treatment issues.
- Different privacy policies and protection levels arise.
- Managing these discrepancies is difficult for businesses due to varying territorial applications.
- Legislations often establish varying territorial scopes for applying data protection rules (data release locations).
- Risk of legal overlapping and uncertain applicable rules can discourage individuals from sharing online data.
Techniques to Escape Data Protection Rules
- Companies employ various techniques to circumvent data protection regulations (U.S. and EU).
- Common techniques include:
- De-identification.
- Anonymization.
- Pseudonymization.
Personal Information Identifiers
- Personal information may contain direct or indirect identifiers.
- Direct identifiers: data that identify a person without extra info (name, phone number, government IDs).
- Indirect identifiers: data that indirectly identify individuals (date of birth, gender, location, cookies, IP address, license plate numbers).
- De-identified data meets U.S. privacy standards but not EU, which requires anonymized data for compliance (GDPR).
Scope of "Personal Data"
- "Personal data" is the core of data protection law (GDPR Article 2(1))
- Data considered personal: any information relating to an identifiable natural person (data subject). Identifiable persons can be directly or indirectly defined by identifiers (name, ID, location, etc.).
- Data that isn't personal is not under data protection laws
Definition of Personal Data
- Personal data is defined as information about a natural person (not a legal entity).
- Data can be in various formats (alphabetic, numeric, video, images).
- Includes both objective and subjective information
Identifiable Individuals
- The Breyer case (Case C-582/14) clarified that a dynamic IP address is personal data, even if the identification method involves several means.
- Identifiability isn't restricted to a single person having the information; the totality of means to identify the person is considered.
Risk of Identification
- The risk of re-identification can be negligible for data classified as anonymous by legislation.
- Data that is practically impossible to re-identify falls into this category.
De-identification
- De-identification methods involve removing personal identifiers.
- Includes different approaches, tools, and algorithms.
- Is crucial for government agencies, businesses for data sharing/research. Medical research greatly benefits.
Anonymization Methods
- Anonymization is a subset of de-identification.
- This method removes personal identifiers irreversibly, preventing re-identification.
Pseudonymization
- Pseudonymization replaces personal identifiers with artificial identifiers (pseudonyms) to reduce re-identification risks.
- Separately maintained information is key, as are technical safeguards.
- EU legislation defines pseudonymization as the data processing that detaches personal data from the original user.
Data Hierarchy Based on Risk
- A hierarchy of data categories based on re-identification risk shows that:
- Personally Identifiable Data (highest risk) has direct and indirect identifiers.
- De-Identified Data (undefined risk) has identifiers removed.
- Pseudonymous Data (remote risk) uses artificial identifiers and safeguards.
- Anonymous Data (zero risk) has technical safeguards preventing re-identification.
U.S. Privacy Law
- U.S. privacy laws define "data not reasonably linkable" based on several conditions:
- Data should be de-identified.
- The company should publicly commit to not re-identifying it.
- Downstream recipient re-identification must be contractually prohibited.
De-identification Methods (NIST)
- Five common methods for de-identification (NIST 2010):
- Suppression.
- Averaging.
- Generalization.
- Perturbation.
- Swapping.
EU Privacy Law (GDPR)
- The GDPR does not apply to identifying data that has been made completely anonymous.
- It's stricter than the US standard and requires demonstrable anonymity (no re-identification risk).
- Includes additional factors or risk levels needed for data to be anonymous under EU law.
Information to E-customers
- Clear communication of data collection information to end-users.
- Essential information to include:
- Company details.
- Data usage explanations
- Categories of the personal data the company is interested in.
- Legal justification for data processing.
- Data preservation duration.
- Other recipients of the data.
- Essential information to include:
EU Data Protection Law - Entities
- Two main entities in data processing:
- Data controller: sets purposes and means of data processing
- Data processor: manages data on behalf of the controller (typically third parties).
- Contracts define processors' responsibilities, especially after data processing agreement termination.
Joint Control
- Organizations can have a joint control relationship when they decide jointly the 'why' and 'how' of data processing.
- A joint control arrangement and responsibilities are defined in relation to GDPR provisions. This is communicated to the relevant data subjects.
Web Cookies
- Web cookies are messages websites exchange with browsers.
- Used for user identification, session management, and page customization.
- Some cookies are short-lived (session), while others persist (persistent).
- Legislation exists and is evolving to limit privacy violations regarding the use of cookies.
