Abstract
Digital data protection is provided by a processor running an operating system programmed to generate one or more interrupts; an access mechanism detects one or more interrupts at or below a BIOS level, a given detected interrupt being associated with an operating system request to access protected portions of the data, and restricts access to the protected portions of the data by the operating system in accordance with at least one rule; a tamper detecting mechanism prevents access to the data in an unprotected form has means for destroying data stored in the access mechanism when tampering is detected.

1-25. (canceled)
A method of authenticating an extract of information in a multimedia application, the method comprising:
- receiving a selection of information to extract;
- in response to receiving the selection of information to extract, extracting the selected information as extracted information;
- digitally signing the extracted information to produce a digital signature on the extracted information;
- and
- providing the extracted information along with the digital signature on the extracted information.
A computer readable memory storing instructions configured to, when executed by a computing device, cause the computing device to perform operations for authenticating an extract of information in a multimedia application, the operations comprising:
- receiving an indication of information to extract, wherein the indication is associated with a parent data source;
- extracting the indicated information from the parent data source;
- digitally signing the extracted information to produce a digital signature, the digital signature configured to indicate that the extracted information has not been subject to unauthorized alterations;
- and
- providing, to the multimedia application, the extracted information along with the digital signature on the extracted information.
A system that authenticates an extract of information in a multimedia application, the system comprising:
- a memory;
- a processor;
- an input interface configured to receive an indication of information to extract, wherein the indication is associated with a parent data source;
- a data extractor configured to access the parent data source and extract the indicated information;
- a verification portion configured to digitally sign the extracted information to produce a digital signature, the digital signature configured to indicate that the extracted information has not been subject to unauthorized alterations;
- and
- an output interface configured to provide the extracted information along with the digital signature on the extracted information.
