Abstract
This application describes methods and systems of performing digital asset management. In one implementation a method of determining whether content should be encrypted when the content is found in an unencrypted form is provided. The unencrypted form of the content includes a digital watermark embedded therein including a message. The method recites: decoding the digital watermark from the encrypted form of the content to obtain the message; based at least in part on the message, determining whether the unencrypted form of the content should be encrypted; and if so decided by the determination, encrypting the unencrypted form of the content. Other implementations and embodiments are provided as well.
Claims21
A method of repackaging content into an encryption container or digital rights management (DRM) container when the content is found outside of a container, the content comprising a digital watermark embedded therein, the digital watermark including a content identifier, said method comprising:
- decoding the digital watermark from the content to obtain the content identifier, the content identifier identifying the content;
- providing the content identifier to a database, the database including usage rules associated with the content identifier, the usage rules comprising at least one rule regarding repackaging;
- based on the repackaging rule, determining whether the content should be repackaged in at least one of an encryption container and DRM container;
- and, if indicated by the determination,
- packaging the content in at least one of an encryption container and DRM container.
A method comprising:
- analyzing a content item to determine whether a digital watermark is steganographically embedded therein;
- and if the digital watermark is detected in the content,
- abiding by a usage rule including at least one of an instruction to encrypt and an encryption protocol;
- and
- encrypting the content item according to the usage rule.
A method comprising:
- analyzing a file header associated with a content item to determine whether the header includes an indicator;
- and if the indicator is detected in the header,
- abiding by a usage rule including at least one of an instruction to encrypt and an encryption protocol;
- and
- encrypting the content item according to the usage rule.
A system for managing a content item comprising:
- a system memory;
- and
- electronic processing circuitry in communication with said memory via a communications bus,
- wherein said memory includes computer executable software instructions stored therein for execution by said electronic processing circuitry, the software instructions including instructions to:
- i) determine whether the content item includes a steganographic identifier embedded therein;
- and if the content does not include the steganographic identifier,
- ii) abide by a default usage rule including at least one of an instruction to encrypt and an encryption protocol;
- and
- iii) encrypt the content item according to the usage rule.
A method of determining whether content should be encrypted when the content is found in an unencrypted form, wherein the unencrypted form of the content comprises a digital watermark embedded therein, the digital watermark including a message, said method comprising:
- decoding the digital watermark from the unencrypted form of the content to obtain the message;
- based at least in part on the message, determining whether the unencrypted form of the content should be encrypted, if so decided by the determination,
- encrypting the unencrypted form of the content.
