Abstract: A method, at a data generation server, for generation of a profile image for downloading the profile image from the profile server to an eUICC hosted in a device, is provided for the purpose of installing a profile corresponding to the profile image in the eUICC. The method includes the steps: Ga) provide, on the data generation server, at least one global identifier and at least a first functionality identifier and a second functionality identifier different from the first functionality identifier; Gb) generate, on the data generation server, at least a first profile image and a second profile image; Gc) assign the at least first and second profile images to the same global identifier; Gd) store the at least first and second profile image as profile images assigned to the same global identifier, for providing the first and second profile image to the profile server for download to eUICCs.

Abstract: A method, on a data generation server, is for preparing generating a profile image for download from a profile server to an eUICC hosted in a device, for the purpose of installing a profile corresponding to the profile image in the eUICC, the method comprising the steps: a) at a data generation server, generate, for multiple devices, multiple non-personalized profile images, each non-personalized profile image comprising at least one functionality identifier specific for the respective device, and each non-personalized profile image not comprising any individual global identifier specific of an individual eUICC, and store the generated multiple non-personalized profile images for providing to the profile server; b) at the data generation server, generate at least one profile-data image, said profile-data image comprising at least one individual global identifier of an individual eUICC, and store the generated at least one profile-data image for providing to the profile server.

Abstract: In a method for the personalization of portable data carriers into a non-volatile memory of the data carrier there are written personalization data, wherein the personalization at first is carried out as a virtual personalization in a virtual data carrier, then a memory image is generated as a bit-true image of a memory of the virtual data carrier and finally the memory image with the aid of its physical memory addresses is directly introduced into the memory of the real data carrier. Here the personalization data in addition to the initialization data also comprise individualization data. Preferably, the introduction of the personalization data into the data carrier can be carried out after the production of the data carrier at an authority issuing the data carrier or at the end user.

Abstract: In a method for the personalization of portable data carriers (700) into a non-volatile memory (350) of the data carrier (700) there are written personalization data (100,101,102), wherein the personalization at first is carried out as a virtual personalization (1000) in a virtual data carrier (500), then a memory image (250) is generated as a bit-true image of a memory (150) of the virtual data carrier (500) and finally the memory image (250) with the aid of its physical memory addresses is directly introduced into the memory (350) of the real data carrier (700). Here the personalization data (100, 101, 102) in addition to the initialization data (90) also comprise individualization data (110, 111, 112). Preferably, the introduction of the personalization data (100,101,102) into the data carrier (700) can be carried out after the production of the data carrier (700) at an authority issuing the data carrier (700) or at the end user.
