System and method for signaling security and database population

A method for facilitating access to metadata associated with a multimedia content, comprising:

• at a first receiver device that includes a first watermark extractor that is implemented at least partially in hardware:
• extracting a plurality of watermark messages from the multimedia content, each of the plurality of watermark messages having been embedded in a segment of the multimedia content;
• using at least a portion of a first watermark message of the plurality of watermark messages to obtain additional information regarding a first segment of the multimedia content that includes the first watermark message by transmitting a query to a metadata server, wherein the query includes a server code and an interval code obtained from the first watermark message;
• and
• associating and storing one or more values of the first watermark message, one or more values of other watermark messages extracted from other segments of the multimedia content by the first watermark extractor, and the additional information to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the other watermark messages;
• subsequent to formation of the table, receiving the multimedia content at a second receiver device that includes a second watermark extractor that is implemented at least partially in hardware and extracting the first watermark message and one or more additional watermark messages from the multimedia content using the second watermark extractor;
• and
• transmitting, for each of the watermark messages extracted by the second watermark extractor, information including a value of the watermark message and a time value to a database, wherein the transmitted information in conjunction with the table or array of items enables the second receiver to transmit information that enables a determination of a particular usage of the multimedia content of the first receiver.

A system comprising:

• a first device comprising a first processor and a first memory comprising processor executable code, the processor executable code when executed by the first processor causes the first device to:
• receive a multimedia content;
• extract a first watermark message from a first segment of the multimedia content using a first watermark extractor;
• use at least a portion of the first watermark message to obtain additional information regarding the first segment of the multimedia content that includes the first watermark message by transmitting a query to a metadata server, wherein the query includes a server code and an interval code obtained from the first watermark message;
• and
• associate and store one or more values of the first watermark message, one or more values of other watermark messages extracted from other segments of the multimedia content by the first watermark extractor, and the additional information to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the other watermark messages;
• a second device comprising a second processor and a second memory comprising processor executable code, the processor executable code when executed by the second processor causes the second device to:
• receive the multimedia content at the second device and extract the first watermark message and one or more additional watermark messages from the multimedia content;
• and
• transmit, for each of the watermark messages extracted by the second watermark extractor, information including a value of the watermark message and a time value to a database, wherein the transmitted information in conjunction with the table or array of items enables the second device to transmit information that enables a determination of a particular usage of the multimedia content of the first device.

A computer program product, embodied on one or more non-transitory computer readable media and comprising:

• program code for extracting a plurality of watermark messages from a multimedia content received at a first device, each of the plurality of watermark messages having been embedded in a segment of the multimedia content;
• program code for using at least a portion of a first watermark message of the plurality of watermark messages to obtain additional information regarding a first segment of the multimedia content that includes the first watermark message by transmitting a query to a metadata server, wherein the query includes a server code and an interval code obtained from the first watermark message;
• program code for associating and storing one or more values of the first watermark message, one or more values of other watermark messages extracted from other segments of the multimedia content by the first device, and the additional information to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the other watermark messages;
• program code for, subsequent to formation of the table, receiving the multimedia content at a second device and extracting the first watermark message and one or more additional watermark messages from the multimedia content at the second device;
• and
• program code for transmitting, for each of the watermark messages extracted by the second device, information including a value of the watermark message and a time value to a database, wherein the transmitted information in conjunction with the table or array of items enables the second device to transmit information that enables a determination of a particular usage of the multimedia content of the first device.
