A method for managing information in a large capacity universal integrated circuit card, comprising: storing content of a file in a mass storage file system of a large capacity universal integrated circuit card; associating the file in the mass storage file system with a file of an ISO file system of the large capacity universal integrated circuit card, wherein the file of the ISO file system is associated with a security configuration defining security requirements for accessing the file of the ISO file system; hiding the content of the file in the mass storage file system by encrypting the content using a key determined by a mass storage secure controller located in the large capacity universal integrated circuit card in order to make the content inaccessible; requesting access by an application running in a host device, which communicates with the large capacity universal integrated circuit card, from the mass storage file system to content of the file in the mass storage file system; and, if the content is hidden, delivering security requirements to the ISO file system by the application and determining whether the delivered security requirements meet the security requirements defined by the security configuration associated with the file of the ISO file system which is associated with the file in the mass storage file system; and, if the security requirements are met, revealing the content of the file in the mass storage file system by decrypting the content using a key determined by the mass storage secure controller of the large capacity universal integrated circuit card. storing content of a file in a mass storage file system of a large capacity universal integrated circuit card; associating the file in the mass storage file system with a file of an ISO file system of the large capacity universal integrated circuit card, wherein the file of the ISO file system is associated with a security configuration defining security requirements for accessing the file of the ISO file system; hiding the content of the file in the mass storage file system by encrypting the content using a key determined by a mass storage secure controller located in the large capacity universal integrated circuit card in order to make the content inaccessible; requesting access by an application running in a host device, which communicates with the large capacity universal integrated circuit card, from the mass storage file system to content of the file in the mass storage file system; and, if the content is hidden, delivering security requirements to the ISO file system by the application and determining whether the delivered security requirements meet the security requirements defined by the security configuration associated with the file of the ISO file system which is associated with the file in the mass storage file system; and, if the security requirements are met, revealing the content of the file in the mass storage file system by decrypting the content using a key determined by the mass storage secure controller of the large capacity universal integrated circuit card. delivering security requirements to the ISO file system by the application and determining whether the delivered security requirements meet the security requirements defined by the security configuration associated with the file of the ISO file system which is associated with the file in the mass storage file system; and, if the security requirements are met, revealing the content of the file in the mass storage file system by decrypting the content using a key determined by the mass storage secure controller of the large capacity universal integrated circuit card.
