Tuesdays the USPTO issues new patents. Both of today's Spotlight Patents concern aspects of digital rights management and both are assigned to Canon (JP).The first patent concerns an access rights system where the user does not install any specific application. The second patent concerns access rights in the context of workflow management.
8,424,097, "Information processing method and apparatus thereof," assigned to Canon (JP)
In an access rights managing system, an application that can set access rights is limited, and if an information apparatus that the user uses does not install any specific application, the system cannot set desired access rights in a digital document. To solve this problem, data is received externally, and first identification information associated with access rights control is extracted from a predetermined position of the received data. Second identification information corresponding to the first identification information is obtained, and is appended to the received data. The received data is then stored in a memory.
8,424,056, "Workflow system and object generating apparatus," assigned to Canon (JP).
A workflow system which restricts improper operations on an object circulated in a workflow by dynamically modifying access rights for the object according to the working status of the workflow. For example, the workflow system is a system which processes an object according to a workflow having a plurality of working statuses. When the working status for the object is changed, a modifying unit modifies access rights applied to the object. A control unit then controls operations on the object based on the modified access rights.
