A real-time information hiding algorithm based on HTTP protocol

Abstract

Based on the structure of HTTP protocol, a real-time information hiding algorithm was proposed in this paper, to solve the problem that embedding a mass of data in the TCP/IP packet. The secret information is embedded in HTTP protocol header fields. It's proved that the capacity of the algorithm is perfect by experiments, and more than 1000 bytes of data could be embedded in a HTTP request-packet (Get-packet), while the transparency is very well. At the same time, the information hidden will not affect on packets transmitting.
