Abstract:
1. A method of limiting transmission of data comprising: generating a first Internet datagram comprising digital content and an Internet protocol (IP) header; if the digital content comprises localized data, setting a time to live (TTL) parameter of the IP header of the first Internet datagram to a first value that represents a number of times the digital content may be transmitted within the local network boundary, wherein the first value is greater than or equal to 1 and less than or equal to 5; after setting the TTL parameter to the first value greater than or equal to 1 and less than or equal to 5, transmitting the first Internet datagram; determining if the received digital content is localized data by determining whether the second Internet datagram originated from a local source; determining if the second Internet datagram has been subjected to tampering by determining whether the TTL parameter of the second Internet datagram exceeds a second value, wherein the second value is greater than or equal to 1 and less than or equal to 5; and automatically discarding the digital content of the second Internet datagram in response to determining that (a) the second Internet datagram originated from a local source and (b) the second Internet datagram was subjected to tampering.
