The publication of the third chapter has not settled this debate and remains silent on whether disclosing pseudonymised data should attract the same data protection obligations as sharing personal data. These include information such as gender, date of birth, and postcode. Further, PII is defined as information: (i) that directly identifies an individual (e.g., name, address, social security number or other identifying number or code, telephone number, email address, etc.) On another desk, you have four books written by George Orwell. Pseudonymisation can also help to make processing permissible which would otherwise not be permissible. To ascertain whether means are reasonably likely to be used to identify the natural person, account should be taken of all objective factors, such as the costs of and the amount of time required for identification, taking into consideration the available technology at the time of the processing and technological developments (Recital 26). Data can be considered "anonymised" from a data protection perspective when data subjects are not identified or identifiable, having regard to all methods reasonably likely to be used by the data controller or any other person to identify the data subject, directly or indirectly. Document who was involved in the assessment (roles), what was taken into consideration, what decisions were made and justification for those decisions. Here we look at what data anonymisation and pseudonymisation actually entail, techniques to employ them, and their uses and risks. When data has been pseudonymised it still retains a level of detail in the replaced data that should allow tracking back of the data to its original state. Pseudonymised Data should include all fields that are highly selective, for example a social security or national insurance number. In the context of data protection law, pseudonymisation refers to the process of replacing, removing or transforming data, so that it is unidentifiable without additional information (e.g. In addition to our previous blog post on the first chapter of the Draft Guidance, this blog post summarises some of the key concepts in the second and third chapters, focusing on pseudonymisation. Pseudonymised Data is not the same as Anonymised Data. Instead, those releasing the data should have employed data blurring techniques to protect the identities of the data subjects. names) if other information that is unique to them remains. Biometric data for the purpose of uniquely identifying a natural person. Each barcode represents a number, which in turn refers to an attendee. It is important to know that pseudonymised data can be assigned to a natural person, provided a key is available. Given the effectiveness of anonymised data in this context, it has been billed by many as . For example a name is replaced with a unique number. You have the right to ask us for copies of your personal information. Although pseudonymised data may be hard to re-identify, it is not exempt from the GDPR. Pseudonymization takes the most identifying fields within a database and replaces them with one or more artificial identifiers, or pseudonyms. The second chapter of the Draft Guidance honed in on the concept of identifiability and its key indicators (i.e. By separating passenger data and travel history, it is possible to find which passenger belongs to which passenger number in one file. Further, PII can be defined as information that: (i) directly identifies an individual (e.g., name, address, Social Security number or other identifying number or code, phone number, email address, etc.) Pseudomization is defined by the UK GDPR as follows: Recital 26 clearly states that pseudonymized personal data remains personal data within the scope of the UK GDPR. Credit card numbers, banking information, tax forms, and credit reports are examples of financial information. Political opinions. The ICOs Code suggests applying a motivated intruder test for ensuring the adequacy of de-identification techniques. Scale down. The file therefore also contains unique data: a passenger can be identified directly by name. Anonymised data is data that cannot be used to identify individuals and is not linked to any individual, not even by study number. Any controller involved in processing shall be liable for the damage caused by processing that infringes this Regulation, the GDPR states.

The question arises as to whether pseudonymised data are no longer personal data and hence no longer subject to the GDPR. In addition, it is recommended to change the cryptographic key regularly to increase security. The researchers highlighted the importance of not publishing data to the level of the individual. As a medical research group, much of the data we hold is special category data. In the upcoming posts of this blog series we will discuss the following topics: Do you want clarity about what the GDPR exactly means for your organisation? As said, a pseudonym can be an alias: a name other than the one in your passport. Anonymised data (or more accurately effectively anonymised data) is not personal data.

Whats more, Recital 78 and Article 25 actually list pseudonymisation as a way to show GDPR compliance with requirements such as privacy-by-design. We do this with an artificially created identifier that we refer to as a study number. This has resulted in organisations adopting differing approaches in relation to data protection compliance when seeking to share pseudonymised personal data, with some organisations taking the view that this can be carried out without needing to comply with data protection obligations that would arise if they were disclosing personal data and other organisations taking a more conservative view and treating such disclosures as instances of regular sharing of personal data. The researchers highlighted the importance of not publishing data to the level of the individual. In contrast, as clarified in the new third chapter of the Draft Guidance which cites Recital 26 of the UK GDPR, there is no change in status of data that has undergone pseudonymisation. These techniques replace or remove all identifying information so that the remaining data is clean and anonymised. The focus of her work is to help customers and interested parties with contributions to the Robin Data Privacy Academy. Certain medical conditions could also be considered identifiers, if they are very rare. Bear with me for a moment while I use an example. The following personal data is considered sensitive and is subject to specific processing conditions: personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs; trade-union membership; data concerning a persons sex life or sexual orientation.

In this process, a state is reached in which, in all likelihood, no one can or would carry out de-anonymisation because it would be far too costly and difficult or impossible. Anonymisation is more commonly used with highly sensitive data, such as medical and financial records. Pseudonymization is a technique that replaces or deletes information from a data set that uniquely identifies an individual. This guidance provides a brief overview of the main differences between anonymisation and pseudonymisation, and how this will affect the processing of personal data. The file contains valuable information that company analysts would like to use for commercial purposes (What are popular destinations? Pseudonymous data still allows for some form of re-identification (even indirect and remote), while anonymous data cannot be re-identified. The third possibility is the assignment by the responsible persons themselves by means of an identification number. You know that George Orwell wrote all four books, even if you dont know that George Orwell was actually Eric Arthur Blair.

Think about who an intruder might be (internal or external) and what their motivations might be: perhaps a disgruntled employee, or to discredit UCL / the research team / the funder, an investigative journalist etc and what measures are being taken to protect the data from those threats. On the other hand, the information on passengers says a lot about passengers and it is not desirable that many airline employees know which passenger is flying where and when. In the calculation method pseudonyms are calculated algorithmically from the identity data.

In 2012, the ICO stated in its Anonymisation Code of Practice that the disclosure of anonymised or pseudonymised data would not amount to a disclosure of personal data, even if the organisation disclosing the data still holds the other data that would allow re-identification. Many things, such as a persons name or email address, can be considered personal data. Pseudonymised data is therefore still personal data, to the extent that it is not effectively anonymised. At this point, its important to distinguish between direct and indirect identifiers. This distinction has an impact on the obligations of the disclosing party prior to making the disclosure. The members of this second team can only access this pseudonymised information. The legal distinction between anonymised and pseudonymised data is its categorisation as personal data. Neither is data anonymisation a failsafe option. whether the person holding the data is able to access and use additional information to identify the data subject (either information in their possession or in the public domain); whether it is reasonably likely that this person will actually identify the data subject (e.g. By applying this test and documenting the decisions, the study will have evidence that the risk of disclosure has been properly considered; this may be a requirement if the study is audited.

However, you cannot (in theory, at least) re-identify anonymous data. Pseudonymous data always allows for some form of re-identification, no matter how unlikely or indirect. to the public. Pseudonymization is intended to minimize the risk of data misuse or loss. Where 'de-identified' or pseudonymised data is in use, there is a residual risk of re-identification; the motivated intruder test can be used to assess the likelihood of this. Protect the information you keep. If a controller discloses parts of a data set from which all original, identifiable data items have not been deleted, the resulting material still contains personal data. The three main types of sensitive information that exist are: personal information, business information and classified information.
