Data access and ownership management

A data processing device comprising:

• processing circuitry;
• communications circuitry;
• and
• computer-readable memory encoded with instructions that, when executed by the processing circuitry, cause the data processing device to:
• obtain, via the communications circuitry, first secret data associated with a first user and corresponding to a first location of a remote resource, the first secret data including a uniform resource locator (URL) transformation including URL encoding information, wherein obtaining the first secret data comprises receiving the first secret data from the remote resource;
• generate, using the first secret data, a first URL usable to obtain the first location of the remote resource;
• access, via the communications circuitry, the first location of the remote resource using the first URL;
• obtain, via the communications circuitry in response to a transfer of usage rights of the data processing device from the first user to a second user, second secret data associated with the second user and corresponding to a second location of the remote resource;
• generate, using the second secret data, a second URL usable to obtain the second location of the remote resource;
• and
• access, via the communications circuitry, the second location of the remote resource using the second URL;
• wherein the second location of the remote resource is inaccessible via the first URL, and wherein the first location of the remote resource is inaccessible via the second URL.

A method comprising:

• generating, by a server system comprising at least one computing device and computer-readable memory, first secret data associated with a first user and corresponding to a first location of the computer-readable memory of the server system, the first secret data including a uniform resource locator (URL) transformation including URL encoding information;
• providing, by the server system to a data processing device, the first secret data for generating a first URL usable to obtain the first location of the computer-readable memory of the server system;
• generating, by the server system in response to a transfer of usage rights of the data processing device from the first user to a second user, second secret data associated with the second user and corresponding to a second location of the computer-readable memory of the server system;
• and
• providing, by the server system to the data processing device, the second secret data for generating a second URL usable to obtain the second location of the computer-readable memory of the server system;
• wherein the second location of the computer-readable memory of the server system is inaccessible via the first URL, and wherein the first location of the computer-readable memory of the server system is inaccessible via the second URL.
