Location-based content protection
First Claim
1. A method, comprising:
- determining a current location for a multimedia device using positional information provided by a cellular network or short-range wireless communication medium;
computing location-based authentication data using the positional information;
encoding multimedia content created on the multimedia device with said location-based authentication data by computing a hash value on a combined expression of the multimedia content, said location-based authentication data and identification data including at least one of user identification data and device identification data, wherein said encoding creates a content identity key that authenticates the multimedia content as being created at a certain physical location and time; and
transmitting the encoded multimedia content to a content certification entity via wireless communication, the content certification entity verifying the authenticity of the encoded multimedia content based on the content identity key prior to distribution.

Abstract
A system and system is disclosed to protect media content via location-based data. Multimedia devices are equipped with locator devices, such as a GPS unit, or similar device. The multimedia devices preferably contain the device'"'"'s International Mobile Equipment Identification (IMEI), and International Mobile Subscriber Identification (IMSI). When multimedia content is created on the multimedia device, such as image or sound files, the present invention encodes the multimedia content with location data from the locator device. Additionally, the multimedia device'"'"'s IMEI and IMSI, as well as the time and the date, may be encoded onto the multimedia content. Under an alternate embodiment, a remote server performs the encoding of the multimedia content.
