Abstract
The present application is related to the field of microchips, for example, microchips on a card, or embedded secure elements called eSE. It is provided a computer- implemented method for updating data stored in data objects on a microcontroller chip (2) or an embedded secure element (eSE) comprising the steps of assigning data objects or pieces of data in a respective data object to a specified security level, and backing up only the data objects or respectively pieces of data in a respective data object which are assigned to a specific security level and optionally the data objects or respectively pieces of data in the lower security levels lower than the specific security level, wherein the backing-up is only allowed if the back-up request is an authorized request, which is specified as being authorized to have access to the respective security level. It is further provided a respective system for executing a backing-up data stored in data objects on a microcontroller chip (2) or an embedded secure element (eSE).
