Abstract

A method and system of binding content at first access is disclosed. A non-volatile storage device may provide a content access script and a content binding script in order to access protected content. An accessing application may attempt to access the protected content by executing a content access script. The accessing application must have permission to access and execute the content access script. If the accessing application cannot access or execute the content access script, the accessing application may access and execute the content binding script. The content binding script contains instructions that enable the accessing application to successfully execute the content access script. The content binding script, when executed, may disable itself from being executed again by moving critical information associated with the access to protected data. Thus, the content binding script may be executed once to enable an accessing application to successfully execute the content access script.

Claims36

Dependent claims

A method of accessing content stored in a non-volatile storage device, the method comprising:

in an accessing device coupled with the non-volatile storage device, the non-volatile storage device comprising a removable non-volatile storage device, the accessing device having a processor and an accessing application executable by the processor, wherein the non-volatile storage device has (i) content, (ii) a content access script associated with the content and including primary instructions to access the content, and (iii) a second script associated with the content and including second instructions to access the content, with the processor of the accessing device, performing:
receiving a request to access the content stored in the non-volatile storage device;
reading the content access script from the non-volatile storage device;
attempting to execute the content access script;
if the content access script successfully executes, accessing the content with the content access script;
and
if the content access script fails to execute:
reading the second script from the non-volatile storage device;
and
executing the second script, wherein the second script, when executed, permits the processor to set a binding and access the content using the content access script, and results in binding the content to a configuration of the accessing application, without communicating with a remote authorization entity, wherein the remote authorization entity is located remotely from the accessing device.
