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.
Claims52
A method of providing trusted multimedia content, originating from a user's multimedia device, comprising:
- retrieving location-based authentication data associated with the multimedia device;
- and
- encoding multimedia content created on the multimedia device with said location-based authentication data, wherein said encoding creates a content identity key that authenticates the multimedia content as being created at a certain physical location and time.
A multimedia device providing trusted media content, comprising:
- a location device, wherein said location device generates location data for determining the physical location of the multimedia device;
- a time device, wherein said time device generates data corresponding to the date and time;
- at least one storage medium for storing data identifying the multimedia device and at least one encryption algorithm;
- and
- a media generation switch, wherein said switch initiates the generation of digital multimedia data and further initiates the at least one encryption algorithm to encode said multimedia data with the location data, and optionally encode the multimedia data with time device data, and/or data identifying the multimedia device.
A method of providing trusted multimedia content through a server, comprising:
- receiving digital multimedia content, created on a multimedia device, through a network;
- receiving location-based authentication data through a network, wherein the location-based authentication data is correlated in the server with the multimedia device that created the multimedia content;
- and
- executing an encryption algorithm, wherein the location-based authentication data is encoded into the multimedia content to create a multimedia content identity key that authenticates the multimedia content as being created at a certain physical location and time.
The method of 31, wherein the location based authentication data further comprises the International Mobile Subscriber Identification (IMSI) of the multimedia device.
A system for providing trusted multimedia content through a server, comprising:
- a storage medium;
- a network interface;
- a processor, coupled to the storage medium and network interface, said processor, storage medium and network interface configured to:
- receive digital multimedia content, created on a multimedia device, through the network interface;
- receive location-based authentication data through the network interface, wherein the location-based authentication data is correlated by the processor with the multimedia device that created the multimedia content;
- and
- execute an encryption algorithm, stored in the storage medium, wherein the location-based authentication data is encoded into the multimedia content to create a multimedia content identity key that authenticates the multimedia content as being created at a certain physical location and time.
Computer executable software code stored on a computer readable medium, comprising:
- code to retrieve location-based authentication data associated with the multimedia device;
- and
- code to encode multimedia content created on the multimedia device with said location-based authentication data, wherein said encoding creates a content identity key that authenticates the multimedia content as being created at a certain physical location and time.
