If a company experiences a data security breach, and receives a “Right to be Forgotten” request from a data subject whose information was involved, does the company have to delete the information that they have about the individual?
When investigating a data security incident, companies are often focused on determining whether there has been unauthorized access or acquisition to personal data, and, if so, which data subjects were impacted. As part of that investigation, companies typically create records that indicate which data subjects were, or were not, impacted by the incident, and attempt to create copies of the records that might have been impacted.
If a company notifies individuals about a data breach, it is not uncommon for some portion of the notified individuals to request that the company delete the information held about them. Such requests raise an inherent conflict. On the one hand, the data subject may no longer wish their information to be in the hands of the company – particularly if they perceive that the company’s security may be inadequate or may have contributed to the data breach. On the other hand, the company has a strong interest in maintaining records relating to the security incident. For example, if a data subject were to bring an action against a company for damages as a result of the security incident, the company has an interest in being able to refer to its internal records to determine if the data subject’s information was involved in the incident, and, if so, what types of data fields may have been impacted. Similarly, if a third party is responsible for a data breach, a company may need the evidence (in an unaltered and authenticated state) in order to bring suit against the third party, or to aid in a criminal prosecution against the individual. The GDPR resolves the conflict by allowing a company to keep personal data – despite a data subject’s request that it be deleted – if data is “necessary . . . for the establishment, exercise or defence of legal claims.”1
In some circumstances, data relating to a breach may no longer be necessary for the purpose of establishing a claim or defense (e.g., if the attacker has already been prosecuted, or the statute of limitations for a third party to bring a claim relating to the incident has expired). In such situations, whether a company must comply with a deletion request depends on the context of a particular incident and whether one of the following criteria applies:
- Companies must delete data upon request if data is no longer necessary. If the personal data that was collected by a company about an individual is “no longer necessary in relation to the purposes for which [it was] collected,” the company typically must honor a right to be forgotten request.2 As a result, if the company no longer needs the data to establish a legal defense or claim, and the data is no longer necessary for the purposes of its original collection, the request to delete should be honored.
- Companies must delete data upon request if the data was processed based solely on consent. If a company’s sole basis for processing data was the consent of the individual, the company is typically required to honor a right to be forgotten request, which might for all practical purposes be viewed as a revocation of that consent. Conversely, if processing is based on an additional permissible purpose (g., performance of a contract) the right to be forgotten request does not necessarily have to be granted.
- Companies must delete data upon request if the data was processed based upon the controller’s legitimate interest, and that interest is outweighed by the data subject’s rights. When processing is based upon a company’s legitimate interest, a data subject has a right to request deletion unless the interest of a controller or a third party is demonstrably “overriding.”3 Whether or not the company’s interest in continuing to keep the information, or the data subject’s interest in having it deleted, control may depend on the precise reasons both parties have for keeping (or deleting) the information.
Like the GDPR, the CCPA contains an exception that permits a company to refuse a deletion request if the information is needed to “[e]xercise or defend legal claims.”4 The CCPA also contains an exception that permits the retention of the information if it is “necessary” to “prosecute those responsible for” a security incident,5 if it is needed for “internal uses that are reasonably aligned with the expectations of the consumer,”6 or if it is necessary for the business to use it internally in a manner that is “compatible with the context in which the consumer provided the information.”7
