Patent ID: 6968498

Claim:
A method for verifying validity of transmission data based on a numerical identifier for said transmission data, said method comprising: generating a first number based on said transmission data wherein said first number is generated based on at least one of a size and a content of said transmission data; obtaining a numerical identifier for said transmission data; generating a second number from said first number and said numerical identifier wherein said second number is a checksum number generated based on a checksum protocol; verifying the validity of said transmission data based on said checksum number wherein said verifying is a checksum verification; generating a checksumed data by including said checksum number with said transmission data; transmitting said checksumed data from a sender to a recipient; and performing said checksum verification by said recipient, wherein said numerical identifier is an address location of said recipient of said checksumed data, wherein said transmission data is a message data and said address location is a network address location of said recipient of said transmitted checksumed data, and wherein said performing said checksum verification by said recipient further comprises: generating a third number based on said received transmission data included in said received checksumed data; obtaining an internet protocol address location of said recipient from said recipient; generating a second checksum number based on said third number and said address location obtained from said recipient; matching said second checksum number to said received checksum number included in said received checksumed data; and verifying the validity of said received checksumed data based on said matching wherein said verification determines at least one of an existence of a corruption in said transmission data and said received checksum number.
