Abstract:
1. A method for a data terminal to access one or more of a number of data objects; stored in an electronic device, whereby: the electronic device is integrated into an identifying document, which includes machine-readable printed data, and the electronic device includes an allocation table in which cryptographic protocols of different security levels are assigned to the number of data objects, the allocation table including: (i) a cryptographic protocol of an elevated security level being assigned to at least a first data object among the number of the data objects, the first data object including personal biometric data, (ii) a cryptographic protocol of a higher security level being assigned to at least a second data object among the number of the data objects, the second data object including personal biometric data, and (iii) at least a third data object among the number of data objects being assigned free access with no assigned cryptographic protocol, and the method comprising the steps of: the data terminal transmitting a request to the electronic device for a particular data object among the number of data objects stored in the electronic device; the electronic device: (i) processing the request received from the data terminal to determine the particular data object, (ii) electronically accessing the allocation table to determine the cryptographic protocol assigned to the particular data object, (iii) selecting the cryptographic protocol from the allocation table assigned to the particular data object, and (iv) specifying to the data terminal the selected cryptographic protocol required for the data terminal to obtain the particular data object from the electronic device; conducting the cryptographic protocol of elevated security level between the electronic device and the data terminal when the particular data object is the first data object and the selected cryptographic protocol is the cryptographic protocol of elevated security level, and transmitting the first data object from the electronic device to the data terminal upon successful completion thereof; conducting the cryptographic protocol of higher security level between the electronic device and the data terminal when the particular data object is the second data object and the selected cryptographic protocol is the cryptographic protocol of higher security level, and transmitting the second data object from the electronic device to the data terminal upon successful completion thereof; and conducting no cryptographic protocol between the electronic device and the data terminal when the particular data object is the third data object and the assigned protocol is free access, and transmitting the third data object from the electronic device to the data terminal, whereby the cryptographic protocol of elevated security level comprises the following steps: whereby the data terminal includes a public key and a private key, and the cryptographic protocol of a higher security level comprises the following steps:
