Method for controlling a data storage device based on a user profile, and associated data storage device
A method for controlling a data storage device is provided, which includes: upon detecting a use of the device by a user, determining whether the user corresponds to an identifier associated with a first user profile including access rights authorizing at least the writing and reading of data in a memory of the data storage device; if it is determined that the user corresponds to the identifier associated with the first user profile, controlling the use of the data storage device according to the first user profile; and if it is determined that the user does not correspond to the identifier associated with the first user profile, controlling the use of the data storage device according to a second user profile including access rights which permit the writing of data in the memory of the data storage device and which prohibit at least the reading of data, in the memory of the data storage device, that were not previously written by the user.
1. A method for controlling a data storage device, comprising the following acts performed by the data storage device:
upon detecting a use of the data storage device by a user by connection to a computing device, determining whether the user corresponds to an identifier associated with a first user profile including access rights authorizing at least writing and reading of data in a memory of the data storage device;
determining whether the user corresponds to the identifier associated with the first user profile and:
in response to determining that the user corresponds to the identifier associated with the first user profile, controlling the use of the data storage device according to the first user profile, otherwise controlling the use of the data storage device according to a second user profile by default, the second user profile including access rights which, for all users not corresponding to the identifier associated with the first user profile, permit the writing of data in the memory of the data storage device and which prohibit at least the reading of data, in the memory of the data storage device, that were not previously written by the user.
2. The method according to claim 1 , wherein the access rights included in the first user profile further authorize deletion of data in the memory of the data storage device, and the access rights included in the second user profile further prohibit the deletion of data in the memory of the data storage device.
3. The method according to claim 1 , wherein the access rights included in the second user profile only authorize the writing of data in the memory of the data storage device and access to information about available data storage capacity in the memory of the storage device.
4. The method according to claim 1 , wherein the access rights included in the second user profile are applicable to a predefined partition of the memory of the data storage device.
5. The method according to claim 1 , wherein the second user profile comprises access rights prohibiting access to information about the data stored in the memory of the storage device.
6. The method according to claim 5 , wherein the second user profile comprises access rights prohibiting display on a display device of information about the data stored in the memory of the storage device.
7. The method according to claim 1 , wherein the second user profile includes access rights authorizing access to information about an available data storage capacity in the memory of the storage device.
8. The method according to claim 1 , wherein the access rights included in the second user profile prohibit the reading of any data stored in the memory of the data storage device.
9. The method according to claim 1 , wherein the access rights included in the second user profile only authorize the writing of data in the memory of the data storage device.
10. The method according to claim 1 , wherein the identifier associated with the first user profile is stored in the memory of the data storage device.
11. The method according to claim 1 , wherein the determination of a correspondence between the user and the identifier associated with the first user profile comprises an identification of the user on the basis of the identifier associated with the first user profile.
12. The method according to claim 11 , wherein the determination of a correspondence between the user and the identifier associated with the first user profile further comprises an authentication of the user on the basis of the identifier associated with the first user profile.
13. A data storage device, comprising:
a processor,
a memory, and
a data transfer interface, configured for exchanging data with a computing device when the data storage device is connected to said computing device,
wherein the processor is configured to implement a method for controlling the data storage device, wherein controlling comprises:
upon detecting a use of the data storage device by a user by connection to the computing device, determining whether the user corresponds to an identifier associated with a first user profile including access rights authorizing at least writing and reading of data in the memory of the data storage device;
determining whether the user corresponds to the identifier associated with the first user profile and:
in response to determining that the user corresponds to the identifier associated with the first user profile, controlling the use of the data storage device according to the first user profile, otherwise controlling the use of the data storage device according to a second user profile by default, the second user profile including access rights which, for all users not corresponding to the identifier associated with the first user profile, permit the writing of data in the memory of the data storage device and which prohibit at least the reading of data, in the memory of the data storage device, that were not previously written by the user.
14. The data storage device according to claim 13 , wherein the data storage device is a removable data storage device, and wherein the data transfer interface is of the Universal Serial Bus (USB) type.
