A computer-implemented method comprising: obtaining, by a computing device (102, 104), entity data associated with an entity, the entity data including at least an item of protected information; applying, by the computing device (102, 104), a transformation function to the item of protected information, or to a portion of the item of protected information, to produce an item of minimized information, wherein the item of minimized information preserves one or more characteristics of the item of protected information while reducing a determinable association between the item of minimized information and the entity; generating, by the computing device (102, 104), in response to a first request of a requesting entity to access at least a portion of the entity data, user interface data renderable to depict a user interface including at least the item of minimized information and excluding the item of protected information; rendering the user interface data to the requesting entity to depict the user interface; receiving, by the computing device (102, 104), a second request of the requesting entity to provide at least the item of protected information corresponding to the item of minimized information; determining, based at least in part on an access level associated with the second request, wherein the access level is determined based at least in part on previous requests to access the item of protected information, that the item of protected information should be provided in response to the request; and updating, by the computing device (102, 104), the user interface data to include the item of protected information. obtaining, by a computing device (102, 104), entity data associated with an entity, the entity data including at least an item of protected information; applying, by the computing device (102, 104), a transformation function to the item of protected information, or to a portion of the item of protected information, to produce an item of minimized information, wherein the item of minimized information preserves one or more characteristics of the item of protected information while reducing a determinable association between the item of minimized information and the entity; generating, by the computing device (102, 104), in response to a first request of a requesting entity to access at least a portion of the entity data, user interface data renderable to depict a user interface including at least the item of minimized information and excluding the item of protected information; rendering the user interface data to the requesting entity to depict the user interface; receiving, by the computing device (102, 104), a second request of the requesting entity to provide at least the item of protected information corresponding to the item of minimized information; determining, based at least in part on an access level associated with the second request, wherein the access level is determined based at least in part on previous requests to access the item of protected information, that the item of protected information should be provided in response to the request; and updating, by the computing device (102, 104), the user interface data to include the item of protected information.
