accountability and governance requirements in the context of anonymisation and pseudonymisation (e.g. Theres no silver bullet when it comes to data security. Pseudonymised data can still be used to single individuals out and combine their data from different records. These include information such as gender, date of birth, and postcode. He is better known under his pseudonym: George Orwell, writer of the famous book 1984. Subsequently, an assignment is made in the form of a table. Recital 26 of the GDPR defines anonymised data as data rendered anonymous in such a way that the data subject is not or no longer identifiable.. Data encryption is useful in storing different indirect identifiers separately a key part of any pseudonymisation technique. Any controller involved in processing shall be liable for the damage caused by processing that infringes this Regulation, the GDPR states. The ICOs Code of Conduct on Anonymisation provides a further guidance on anonymisation techniques. The goal is to eliminate some of the identifiers while maintaining data accuracy. By separating passenger data and travel history, it is possible to find which passenger belongs to which passenger number in one file. We suggest involving members of the study team to ensure a wide range of input is captured. It is irreversible. destroys any way of identifying the data subject. De-identifying data (pseudonymisation or anonymisation) is the process of removing identifiers that lead to the natural person. Pseudonymisation means the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information. }0 )Z% The researchers highlighted the importance of not publishing data to the level of the individual. translates data into another form, so that only those with access to a a decryption key, or password, can read it. According to the Information Commissioners Office (ICO), this is any information relating to an identifiable natural person (data subject) who can be directly or indirectly identified in particular by reference to an identifier. Following on from the first and second chapters published on 28 May 2021 and 8 October 2021, respectively, which focus on anonymisation, the new third chapter aims to clarify the much debated concept of pseudonymisation. Whilst this statement is not entirely conclusive, it does suggest that the ICO may be comfortable with organisations sharing pseudonymised data which is effectively anonymised in the receiving partys hands without needing to adhere to the data protection obligations that would otherwise apply when disclosing personal data, including in relation to transparency and the considerations set out in the ICOs Data Sharing Code (see our blog post on the Code here). Swapping attributes (columns) that contain identifiers values such as date of birth, for example, may have more impact on anonymization than membership type values. https://media.robin-data.io/2023/03/13123906/Compliance-Management.jpg, https://media.robin-data.io/2022/07/05140916/Robin-Data_ComplianceOS_white_logo.png, https://media.robin-data.io/2022/05/23150310/Datenschutzpanne.jpg, https://media.robin-data.io/2022/05/23150319/EU-US-Privacy-Shield.jpg, Demos for the Robin Data Software [online] , Hacks for the Robin Data Software [online] , Meet the Experts on Data Protection and Information Security [online] , The activity report according to the GDPR. Personal data is also classified as anything that can confirm your physical presence in a location. For example, Cruise could become Irecus. Sensitive data, on the other hand, will usually fall into these special categories: data that reveals racial or ethnic origins, political opinions, religious or philosophical beliefs, and so on. etc.). They may, however, reveal individual identities if you combine them with additional information. Pseudonymised data should be treated as [Personal Identifiable Data] and be secured appropriately [] A data sharing agreement should be in place when pseudonymised information is to be transferred to a third party.. Pseudonymisation can reduce the risks to individuals. to replace an artificial identifier in data that identifies an individual in a way that allows for re-identification. In order to lawfully process special category data, controllers must identify both a lawful basis under Article 6 and a separate condition for processing special category data under Article 9.. 'Pseudonymisation' of data (defined in Article 4 (5) GDPR) means replacing any information which could be used to identify an individual with a pseudonym, or, in other words, a value which does not allow the individual to be directly identified. A single pseudonym for each replaced field or collection of replaced fields makes the data record less identifiable while remaining suitable for data analysis and data processing. An example of an organisational measure is to ensure that the number of people within the airline with access to both files is very limited. Pseudonymization is a method that allows you to switch the original data set (for example, e-mail or a name) with an alias or pseudonym. It is of course important (and also required in the GDPR) that these files are kept separately. Therefore, pseudonymised data qualify as personal data; with the conclusion that the GDPR applies to the processing of these data. Encryption is understood as a process in which a clearly readable text or other type of information is converted by an encryption process (cryptosystem) into an unreadable or uninterpretable character string. 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. 759 0 obj <> endobj They do not constitute legal advice and should not be relied upon as such. Ms. Schwabe is an information designer and Data Protection Officer. Having said this, the ICO does mention in the introduction to the third chapter that organisations may be able to disclose a pseudonymised dataset (without the separate identifiers) on the basis that it is effectively anonymised from the recipients perspective. For example, Cruise could become Irecus. There are many reasons an author may choose to use a pseudonym instead of their own name, such as to avoid controversy or to create a persona.Many women authors throughout history have used a male or . Enrollment records and transcripts are examples of educational information. : It will allow to limit data protection risks.It will reduce the risks of questions, complaints and disputes regarding personal data disclosure. This definition provides for a wide range of personal identifiers to constitute personal data, including name, address, identification number, location data or online identifier.

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.) 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. As a result, it is considered personal data by the GDPR. Also known as "de-identification", pseudonymisation is the process of separating data from direct identifiers so that discovering the identity of an individual is not possible without additional data. Pseudonymisation is a technique that replaces or removes information in a data set that identifies an individual. A home address is required. Anonymous data is any information from which the person to whom the data relates cannot be identified, whether by the company processing the data or by any other person. There was simply too much information available in the dataset to prevent inference, and so re-identification. Sensitive data, on the other hand, will generally be information that falls under these special categories: Data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs. The rationale behind this position appeared to have been the ICOs keenness to incentivise organisations to anonymise or pseudonymise data if they were going to share data, in order to protect data subjects. Personal data is any information that relates to an identified or identifiable living individual. Despite any measures you put in place, you can re-identify pseudonymous data precisely because it is a reversible process. For the holder of the code key, however, decoding the records and identifying each data subject remains a simple task. You may know these words better as 'anonymous data' or pseudonymous data,' but what do they actually mean? Online and offline training in the area of data protection and information security, Get valuable information and news about data protection and information security, Receive support in the implementation of your company data protection. technological solutions, data sharing options and case studies to demonstrate best practice as well as how the guidance should be implemented. A pseudonym is a false name or alias that clearly deviates from someone's real name and that can be used to shield your identity whenever you face publicity - as some writers do. This could be for example only the manager IT and his assistant. Pseudonymous data still allows for some form of re-identification (even indirect and remote), while anonymous data cannot be re-identified. Under certain circumstances, any of the following can be considered personal data: A name and surname. The second chapter of the Draft Guidance honed in on the concept of identifiability and its key indicators (i.e. TimesMojo is a social question-and-answer website where you can get all the answers to your questions. The situation is different for anonymised data. You know that George Orwell wrote all four books, even if you dont know that George Orwell was actually Eric Arthur Blair. What is the difference between pseudonymous and anonymous data? Find out what pseudonomised data is according to GDPR and what you have to observe in terms of data protection law. Pseudonymous data always allows for some form of re-identification, no matter how unlikely or indirect. The GDPR distinguishes between anonymised and pseudonymous data. now or in the past; and employer's name, address, and telephone number. of US citizens if you know their gender, date of birth and ZIP code. Personal data is information that relates to an identified or identifiable individual. The next chapters are likely to focus on the following issues: Since topics are explored iteratively, it remains to be seen as to whether the ICO will revisit the above issues relating to pseudonymised data in the context of data sharing we will be keeping an eye on this issue in the coming months. There was simply too much information available in the dataset to prevent inference, and so re-identification. Pseudonymization is a data management and de-identification procedure by which personally identifiable information fields within a data record are replaced by one or more artificial identifiers, or pseudonyms. . Political opinions. Pseudonymization is intended to minimize the risk of data misuse or loss. More broadly, as an international company, you can leverage pseudonymisation to utilise relevant data for marketing purposes across borders.
